Huge Drone Swarm to Form Giant Advertisement Over NYC Skyline

Someone apparently thought it was a great idea to fly 500 drones over NYC as part of an ad experiment without much warning.

Droning On

Someone thinks it's a great idea to fly 500 drones over New York City to create a huge ad in the sky on Thursday evening. Because New Yorkers certainly don't have any historical reason to mistrust unknown aircraft over their skyline, right?

As Gothamist reports, the drone swarm is part of a "surreal takeover of New York City’s skyline" on behalf of — we shit you not — the mobile game Candy Crush.

Fernanda Romano, Candy Crush's chief marketing officer, told Gothamist that the stunt will "turn the sky into the largest screen on the planet" using the small, light-up drones.

Though this is not the first time the Manhattan skyline has been used as ad space — that distinction goes to the National Basketball Association and State Farm, which did a similar stunt this summer during the NBA draft — local lawmakers are ticked off about it nonetheless.

"I think it’s outrageous to be spoiling our city’s skyline for private profit," Brad Hoylman, a state senator that represents Manhattan's West Side in the NY Legislature, told the local news site. "It’s offensive to New Yorkers, to our local laws, to public safety, and to wildlife."

Freak Out

Indeed, as the NYC Audubon Society noted in a tweet, the Candy Crush crapshoot "could disrupt the flight patterns of thousands of birds flying through NYC, leading to collisions with buildings" as they migrate.

Beyond the harm this will do to birds and the annoyance it will undoubtedly cause the famously-grumpy people of New York, this stunt is also going down with very little warning, considering that Gothamist is one of the only news outlets even reporting on it ahead of time.

While most viewers will hopefully be able to figure out what's going on pretty quickly, the concept of seeing unknown aircraft above the skyline is a little too reminiscent of 9/11 for comfort — and if Candy Crush took that into consideration, they haven't let on.

So here's hoping this event shocks and awes Thursday night city-goers in a good way, and not in the way that makes them panic.

That "Research" About How Smartphones Are Causing Deformed Human Bodies Is SEO Spam, You Idiots

That

You know that "research" going around saying humans are going to evolve to have hunchbacks and claws because of the way we use our smartphones? Though our posture could certainly use some work, you'll be glad to know that it's just lazy spam intended to juice search engine results.

Let's back up. Today the Daily Mail published a viral story about "how humans may look in the year 3000." Among its predictions: hunched backs, clawed hands, a second eyelid, a thicker skull and a smaller brain.

Sure, that's fascinating! The only problem? The Mail's only source is a post published a year ago by the renowned scientists at... uh... TollFreeForwarding.com, a site that sells, as its name suggests, virtual phone numbers.

If the idea that phone salespeople are purporting to be making predictions about human evolution didn't tip you off, this "research" doesn't seem very scientific at all. Instead, it more closely resembles what it actually is — a blog post written by some poor grunt, intended to get backlinks from sites like the Mail that'll juice TollFreeForwarding's position in search engine results.

To get those delicious backlinks, the top minds at TollFreeForwarding leveraged renders of a "future human" by a 3D model artist. The result of these efforts is "Mindy," a creepy-looking hunchback in black skinny jeans (which is how you can tell she's from a different era).

Grotesque model reveals what humans could look like in the year 3000 due to our reliance on technology

Full story: https://t.co/vQzyMZPNBv pic.twitter.com/vqBuYOBrcg

— Daily Mail Online (@MailOnline) November 3, 2022

"To fully realize the impact everyday tech has on us, we sourced scientific research and expert opinion on the subject," the TollFreeForwarding post reads, "before working with a 3D designer to create a future human whose body has physically changed due to consistent use of smartphones, laptops, and other tech."

Its sources, though, are dubious. Its authority on spinal development, for instance, is a "health and wellness expert" at a site that sells massage lotion. His highest academic achievement? A business degree.

We could go on and on about TollFreeForwarding's dismal sourcing — some of which looks suspiciously like even more SEO spam for entirely different clients — but you get the idea.

It's probably not surprising that the this gambit for clicks took off among dingbats on Twitter. What is somewhat disappointing is that it ended up on StudyFinds, a generally reliable blog about academic research. This time, though, for inscrutable reasons it treated this egregious SEO spam as a legitimate scientific study.

The site's readers, though, were quick to call it out, leading to a comically enormous editor's note appended to the story.

"Our content is intended to stir debate and conversation, and we always encourage our readers to discuss why or why not they agree with the findings," it reads in part. "If you heavily disagree with a report — please debunk to your delight in the comments below."

You heard them! Get debunking, people.

Terraforming – Stellaris Wiki

Version

Celestial body

Terraforming is the act of changing the planet classification of a planet in order to make it more habitable for the empire's species. The base technologies requires significant society research to unlock and each terraforming project requires significant investments of Energy and time.

The first time a planet is terraformed, there's a chance of triggering a terraforming event. Terraformed planets can't get colony events.

Terraforming is started via a button in Planet Detail view. The world must be surveyed and within your borders. Only habitable worlds and barren worlds that have the rare Terraforming Candidate modifier can be terraformed. The expansion planner screen can be used to find these rare candidates.

It is possible to terraform inhabited planets if the empires has the Ecological Adaptation technology. Doing so inflicts a 20% Happiness penalty on the planet for the duration of the procedure.

Ecumenopolis worlds are created via decisions rather than terraforming. They must be inhabited but pops do not suffer a happiness penalty during the process.

The following planet modifiers are always removed when terraforming a planet:

If the planet is being terraformed into either a Machine or Hive World the following modifiers are also removed:

If the planet is terraformed into a Machine World, the Paradise Made modifier is also removed. Additionally, if there are any Pops on the planet without the Cybernetic, Mechanical, or Machine traits, they're all killed and an Organic Slurry deposit is added.

When and if terraforming a planet to Hive or Machine World, keep in mind that all planetary features, excluding a few rare ones that give access to rare resources, will always be removed.

Terraforming cost and speed can be affected by the following:

Terraforming Mars (board game) – Wikipedia

2016 strategy board game

Terraforming Mars is a board game for 1 to 5 players designed by Jacob Fryxelius and published by FryxGames in 2016, and thereafter by 12 others, including Stronghold Games.

In Terraforming Mars, players take the role of corporations working together to terraform the planet Mars by raising the temperature, adding oxygen to the atmosphere, covering the planet's surface with water and creating plant and animal life.[1] Players compete to earn the most victory points, which are measured by their contribution to terraforming and to human infrastructure. Players accomplish these goals by collecting income and resources which allow them to play various projects, represented by cards (drawn from a deck of over 200 unique cards), which increase their income or resources or directly contribute to terraforming the planet or building infrastructure.

The game has been well received by fans and critics, winning and being nominated for multiple awards and accolades.

Players represent competing corporations who all have a stake in terraforming Mars. The game board depicts the planet's surface, which is represented by an array of 61 contiguous hexes. Each hex represents about 1% of Mars' surface area. Onto these hexes, players can place oceans, greeneries, cities, and other special tiles.[2] The object of the game is for players to complete three terraforming conditions: raise the atmosphere's oxygen level to 14%; raise the temperature from 30 to +8 degrees Celsius; and cover 9% of Mars' surface by ocean (represented in-game as having 9 ocean tiles placed on Mars).

Players accomplish these goals by playing cards that represent various technologies or buildings used to terraform Mars.[2][3] The game is played over a number of generations, each represented as one game round. A generation begins with players drawing cards, then players take turns performing actions (which can be playing cards, using the ability of a card already in play or paying for one of the several actions depicted on the board). Once all players have finished taking actions, players collect income and resources according to their production of the different resources, then the next generation begins.

One of the unique aspects in Terraforming Mars is the Terraforming Rating (TR) system. Whenever a player performs an action that advances one of the terraforming conditions, the player's TR increases. A player's TR not only represents the victory points they have earned during the game, but is also added to a player's money income when collecting income and resources at the end of each generation.

The game ends at the end of any generation when the three terraforming conditions have been met.[4][5] Then, players count up their points, which come from their TR at the end of the game, cities and greeneries that they have placed on Mars, achievements they have claimed during the game and cards they have played, and the player with the highest score wins.

Five expansions have been released:[6][7][8][9]

Terraforming Mars: Ares Expedition, a simplified card game version of the original, released in 2021.[10] A legacy variant and a dice game are also scheduled for release.[11][12]

A video game adaptation of Terraforming Mars, developed by Asmodee Digital, was released in October 2018. Matt Thrower of Strategy Gamer considered the adaptation to have "too many rough edges to recommend".[13] However, in a list of Best Board Games On PC from the same site he later revised this opinion, saying "developer Asmodee Digital has stepped up the plate with a host of updates. And while the interface remains a bit obtuse, the game itself is shining as it should."[14]

Popular Mechanics named Terraforming Mars as one of its 50 best games of the year.[15] Polygon named Terraforming Mars its runner up for best game of 2016 and best strategy game of 2016,[16] Ars Technica listed the game as one of its 20 best games of 2016,[17] and Vulture called it "the best high strategy game of 2016."[18] In an article for The Guardian, Dan Jolin stated that it "isn't just a great science game, it's a great game full stop".[19]

The game was nominated for the 2017 Kennerspiel des Jahres award for Best Strategy Game of the Year.[20] It won Best Family/Adult Game at the 2017 Deutscher Spiele Preis.[21] As of 2021, Terraforming Mars is ranked 4th among all board games on BoardGameGeek.[22]

Hellas and Elysium and Venus Next were the two runners-up for the Golden Geek award for the best expansion to a game in 2017.[23]

Prelude has been received very well by critics for speeding up the beginning phase by giving each player extra abilities at the start of the game.[24]

In the 2022 movie Moonshot, a family is seen playing Terraforming Mars while on Mars.

Terraforming Mars Ares Expedition Review – Just Push Start

Terraforming Mars Ares Expedition is the brand new engine building card game from publishers FryxGames and Stronghold Games. Designed by Sydney Engelstein, Jacob Fryxelius and Nick Little, the game sees 1 4 players once again go to Mars, with the objective of terraforming the planet. Described solely as a card game, gamers may be confused how the original TM title wasnt a card game also. With streamlined elements, oceans, temperature and oxygen are still the objectives. So, is this just more of the same? Lets find out!

To set up the huge deck of project cards is shuffled, with 8 cards dealt out to each player. Each player also receives 2 corporation cards. These give each player unique starting resources, as well as an ability to use during play. For example, the Ecoline corp starts with only 27 megacredits (MC) but 1 plant production and forest tokens are cheaper for them. Another, the Credicor corp, starts with 48 MC and gains a discount on projects costing more than 20 MC.

At this stage players can freely discard any number of project cards to redraw the same number, with no costs for keeping cards. A small central board is filled with facedown ocean tiles added and tokens are placed onto the bottom of the three terraforming parameter tracks. With each player choosing a colour, they take the cubes of that colour placing one on the 5th space of the terraforming tracker. Lastly, they take a player board and a set of 5 phase cards.

At the start of a round all players simultaneously look at their phase cards and choose one keeping it face down. Choosing a phase guarantees itll be performing in that round and also gives the player a small bonus/cost reduction. Once all players have chosen, the cards are revealed and which phases the round will include is determined. Players can choose to use the included phase tokens to indicate what is included by flipping them to the active/inactive sides. Importantly, a phase will not occur if it was not selected by a player.

The activated phases are always played in a specific order. All players can perform the activated phase simultaneously regardless of whether it was chosen by themselves or others. First is the development phase, which lets players play a green project card from their hand, paying its cost and minding any requirements. Those that chose the phase can do this with a 3 megacredit discount. Next, is the construction phase, where players can play a blue or red production card. Those that choose the phase can then either play a second blue/red card or draw a card from the deck.

The action phase is then triggered if active in the round. This enables the player to activate each of their blue action cards once, and perform standard actions as many times as they can afford. Those that selected Action can then perform one of their blue card actions a second time. Production is the fourth phase, with each player then collecting resources based upon their constructed green project cards, corporation card and for megacredits also their position on the terraforming rating tracker. Those that selected production get a bonus 4 megacredits for choosing the phase. The final possible phase is the research phase, which sees all players draw two cards and keep one. Those that chose the phase instead draw five cards and keep two.

Whenever a player raises the temperature, increases the oxygen (via a card effect or building greenery) or flips an ocean they gain a terraforming rating, and points are the aim of the game. As the phases are performed simultaneously there are single rounds when the terraforming parameters reach their limit. For these rounds only a player can effectively push the parameter higher than the top, still gaining the Terraforming Rating increase. In rounds after a parameter hits the limit then this cannot be done, though greenery can still be built.

At the end of each phase players check to see if the parameters have all reached their limits: all 9 ocean tiles flipped, temperature at +8 degrees and 14% oxygen. If this is the case the game ends at the end of the current phase, not the current round. Checking takes seconds, so it doesnt become disruptive. Plus, players will want to stay up-to-date on the parameters anyway; not only to see when the end of the game will occur but some cards cannot be played until certain parameters have been reached.

If the limits havent been reached at the end of a round then another round occurs, with no fixed amount of rounds. Importantly, players cannot pick the same phase two rounds in a row, which only makes the decision of when to pick something harder. When the game ends players calculate their points, based on their terraforming rating, forest tokens for greenery and any points on constructed cards. Whomever has the highest points wins, with ties split but combined heat, plant and megacredit resources.

The aim might be the same as the original game and even what cards may offer production wise is similar. However, the core is very different. Gone is the board control element, so thats a huge chunk not needing to be closely followed by players. The managing of resources is still there for paying for cards and working towards the terraforming actions, though this is somewhat streamlined so there is again less to keep track of. The way that not everything can be done in a round and the process behind determining what phases are in a round is what changes things.

The logics learnt of generations in the original to Terraforming Mars Ares Expedition is interesting to get past. What might be an incredible action in Terraforming Mars where it could be used once a generation suddenly isnt as good in this game where that specific phase of the round might not occur. This choice of phases can be as important as what cards someone has played, as its pointless having blue action cards played if theres never the Action phase to activate them.

As more players play Terraforming Mars Ares Expedition the more phases occur each round, so rounds go on longer but feel more fulfilling. Its not a certainty though, and theres always a bit of a laugh when everyone takes a while choosing which phase to select, only for everyone around the table to have picked the same one. At 2 players the rounds can be zoomed through with only a couple of phases activated. The game doesnt seem to massively speed up or down with more phases as the amount of terraforming doesnt change and with income not based on rounds it isnt like a 2 player game sees resources be any more plentiful.

Analysis Paralysis prone players, where it takes you a long time to make any choice, beware. There are countless choices to make every single round. Not just which cards you want to play but what phases you want to occur, combined with determining what phase an opponent might play. There are a lot of avenues of possibility resulting from the choices made and if you sit and calculate them all then the game can go on for as long as a normal Terraforming Mars game, despite this having the streamlined potential to be an hour long experience.

One issue many had with the original was the visual presentation and production. The fact that the likes of Etsy are full of dual layered player boards was a testament of that. Terraforming Mars Ares Expedition steps up the game, coming with those dual layer player boards from the offing. With over 200 cards included in the game the interface of the cards has been updated, which allows a consistent look across the deck. On top of this the full deck uses one art style, giving the game a stunning look.

Included in the box is a very black and write, almost prototype, looking extra rulebook. This quickstart guide hasnt received the luxury rulebook treatment but is phenomenal for those whom have played Terraforming Mars before. Bullet pointed are all the tweaks and changes, as well as the similarities, to the original game, with quick setup reminders and a brief outline of the phases and rules. This isnt just useful for those that played the original though, it can be used by those returning to Ares Expedition to skim the rules and get playing quicker.

The big question for many is if they didnt like the original, or loved it, would they enjoy Terraforming Mars Ares Expedition. There has been a big change in the flow of the experience, with players actively choosing the phases of each round that will be performed. This is a distinct change from the original that allows the game to feel like its own experience whilst still drawing on a lot of Terraforming Mars for the rest.

Its perhaps the streamlining that many will find more exciting, as the original was never a short game. With less to track and faster, simultaneous, turns this could convince many who were put off by the length of the original. Despite the changes, it isnt too distant. With the logics of playing cards, restrictions, costs and benefits being similar, fans of the series will pick the experience up quickly, and unless their favourite part was the slowly controlled and terraformed board in the middle, they should at the very least enjoy Terraforming Mars Ares Expedition.

Terraforming Mars Ares Expedition Review - Just Push Start

Was Voltaire the First Sci-Fi Author? – WIRED

Ada Palmer is a professor of European history at the University of Chicago. Her four-volume science fiction series, Terra Ignota, was inspired by 18th-century philosophers such as Voltaire and Diderot.

I wanted to write a story that Voltaire might have written if Voltaire had been able to read the last 70 years worth of science fiction and have all of those tools at his disposal, Palmer says in Episode 495 of the Geeks Guide to the Galaxy podcast.

Palmer says that Voltaire could actually be considered the first science fiction writer, thanks to a piece he wrote in 1752. Voltaire has a short story called Micromgas, in which an alien from Saturn and an alien from a star near Sirius come to Earth, and they are enormous, and they explore the Earth and have trouble finding life-forms because to them a whale is the size of a flea, she says. They eventually realize that that tiny little speck of wood on the ground is a ship, and its full of living things, and they make contact. So its a first-contact story.

Mary Shelleys 1818 novel Frankenstein is often considered the first science fiction novel. Voltaire was writing much earlier than Shelley, so does he deserve the title instead? It depends on your definition of science fiction.

[Micromgas] doesnt involve technology, Palmer says, so if you define science fiction as depending upon technologyand being about, in the Frankenstein sense, Is mans knowledge giving us access to powers beyond what weve had before? What does that mean?it isnt asking that. But aliens and first contact is a very core science fictional element.

So theres no clear-cut answer to the question of who should be considered the first science fiction writer. Given a sufficiently loose definition of the term, even a 2nd-century writer like Lucian of Samosata could be a candidate. Ultimately, Palmer says its more important to ask the question than to arrive at any particular answer.

I dont want to argue, Yes definitely, everybodys histories of science fiction should start with Voltaire,' she says. But I do want to argue that everybodys histories of science fiction will be richer by discussing whether Voltaire is the beginning of science fiction, or whether its earlier or whether its later. Because that gets at the question of what science fiction is.

Listen to the complete interview with Ada Palmer in Episode 495 of Geeks Guide to the Galaxy (above). And check out some highlights from the discussion below.

Ada Palmer on science fiction conventions:

The wonderful thing about science fiction and fantasy fandom, unlike so many other literary genres, is that when you go to a conference, the author isnt off in the green room and only occasionally appearing for an event and then vanishing; the authors are hanging out in the halls, and you can chat with people, and you get to know people through the internet. So I got to know lots of authors from meeting them at conventions, and from being a panelist before I was an authorbecause I would be talking about music, or I would be talking about history, or I would be talking about anime and manga and cosplay, which were all arenas that I worked in. So I got to know people, and be known by people, through that wonderful and often so supportive world.

Ada Palmer on the Terra Ignota series:

Theres this global network of flying cars so fast they can get you from anywhere on Earth to anywhere else on Earth in about two hours. So suddenly everywhere on Earth is commuting distance. You can live in the Bahamas and have a lunch meeting in Tokyo and eat at a restaurant in Paris, and your spousewho also lives in the Bahamascan have a lunch meeting in Toronto and another one in Antarctica, and this is a perfectly reasonable travel day, especially with self-driving vehicles that let you do work while youre in the car. So once thats been true for a couple of generations, people dont live in a place because they have political ties with it, they live in a place because theres a great house there that their parents really liked at the time their parents were buying a house, and it no longer makes sense for geography to be the determiner of political identity.

Ada Palmer on the Terraforming Mars board game:

The players are each a corporation, and the UN is giving you funding to incentivize this, but you also make profits on your own, and youre competing with the other corporations to terraform Mars best Ive noticed from playing Terraforming Mars that if you play it competitively, and then separately you play it collaboratively, where you say, OK, were going to ignore competing with each other for points, and were going to work together to try to make sure that all the resources end up in the hands of the company that will use them the most efficiently, you terraform Mars way better, way faster. So the board game is intended to be a celebration of this capitalist model of doing space but actually also shows that just teaming up and everyone helping everyone get ahead makes everyone score more and achieve more terraforming of Mars.

Ada Palmer on Diderot:

[Jacques the Fatalist] is Diderots strange 18th-century philosophical novel about the meanderings of a man whos a valet in the company of his master. It has this exquisitely warm prose style, in which Diderot directly addresses the reader with great intimacy and vulnerability Reading that book feels like reading a time capsule, where youre meeting Diderot and being his friend, in a way thats very different from any other book that Ive ever read. You come out of the end of it feeling like Diderot has shared his raw, incomplete, uncertain, deeply, deeply human thoughts and feelings with you, and asked for your thoughts and your opinions in return, in a way thats just exquisite.

Why Earth is habitable but Venus looks like hell – Big Think

If you were a humanoid space traveler visiting our Solar System for the first time and looking for a new place to call home, you would be happy to find two large terrestrial worlds: Earth and Venus. The large size of these worlds (as compared to smaller Mars and tiny Mercury) would matter to you because only larger planets have enough gravity to keep an atmosphere for many billions of years. As you traveled closer, you would see that the two worlds were so similar in radius, mass, and composition that they could be twins. Sure, Venus was closer to the Sun than Earth, so it should be somewhat hotter, but a little terraforming could take care of that.

But then as you neared Venus, your dream of an almost habitable world would vaporize. Rather than being a little hotter than Earth, temperatures on Venus are over 800 F, and its atmosphere is so thick that surface pressures could crush a nuclear submarine. If Earth looked like a Garden of Eden to you, Venus would appear as a living hell.

So, what the hell happened? How did these two worlds end up with such divergent histories?

There are still many unanswered questions about Venus past, but it does seem like we understand the outline of the most basic question about Venus: Why is it so insanely hot? Just being closer to the Sun is not enough to give the right answer. Instead, the real culprit is something called the runaway greenhouse effect.

The Venetian atmosphere is heavy with carbon dioxide (CO2). The Earths atmosphere is 78% nitrogen, 21% oxygen, and 1% everything else. CO2 comes in at a mere 0.039% of the air you are breathing right now. That is a small fraction for a molecule that, as we will see, has a big role to play in our story. For Venus, on the other hand, CO2 is pretty much all there is to the atmosphere. It accounts for more than 95% of all its gases.

Why does this matter? As everyone on Earth is learning via global warming, the greenhouse effect occurs when sunlight (which comes at mostly shorter wavelengths) warms the ground, causing it to radiate its own longer wavelength (thermal) radiation. CO2 is very efficient at absorbing this light and trapping energy that normally would have escaped into space. This means putting more CO2 in the atmosphere is like throwing a blanket over your planet. With so much CO2 in Venus atmosphere, its surface temperature rose until the whole world became a scalding hellscape.

Given this basic planetary physics, the question now becomes: Where did all the CO2 come from? Thats where the runaway part of the runaway greenhouse effect appears.

The principal way CO2 gets added to a planets atmosphere is through volcanic eruptions. Molten rock explodes through the surface, venting huge amounts of CO2. Radar imaging of Venus shows ample evidence for volcanism in the recent past (meaning the last hundreds of millions of years). But what volcanoes give, water can take away. Weathering by water in the form of rain and rivers breaks rocks down to their chemical components. Later these molecular components can bind with CO2 and get packed back into solid forms that is, rocks. This is the basic process creating what are called carbonate minerals (like the limestone under Miami).

So, CO2 belched into a planets atmosphere via volcanoes can go back into the ground as rocks. Any form of plate tectonics means the rocks will go back into the planets lower regions where they melt. Eventually, this CO2 will find its way back into the atmosphere through future volcanic eruptions. It is a geological cycle that regulates the CO2 levels and the greenhouse effect on planets. It is also a cycle that appears to have been broken on Venus.

At some point, Venus likely had more water. But when some of that water evaporated, it made it high into the atmosphere as water vapor (that is, H20 molecules in the air) and a deadly process began. Close to the edge of space, UV radiation from the Sun (the same kind of radiation that causes skin cancer) zapped the water molecules and broke them apart into hydrogen and oxygen. Hydrogen, being the lightest of all elements, easily escaped into interplanetary space as soon as the water molecules were broken apart. With the hydrogen gone, there was no chance for the broken water molecules to reform. Over time and high in its atmosphere, Venus was bleeding its precious water into space.

The planets water loss resulted in what scientists call a positive feedback loop on climate. More water loss meant less rock erosion and less CO2 bound up in rocks. More CO2 in the atmosphere meant more greenhouse effect and higher temperatures. But higher temperatures meant yet more water loss, which feeds the vicious cycle. On Earth, there is no danger of losing our water in the way Venus did because our atmosphere has a cold layer relatively close to the ground. This cold trap condenses water into rain before it gets to the upper reaches of the atmosphere.

All of this means that, in the past, Venus may have been a very different world from what we see now. There are scientists who even believe that Venus may have held vast oceans and been a blue world. There might even have been life, like on Earth. But somewhere along the way, a combination of furious volcanic activity and the loss of that water to space condemned our sister planet.

Elon Musk Terraforming Mars: He Says We Need ‘Glass Domes …

Mark Stevenson/Stocktrek ImagesGetty Images

Earlier this week, SpaceX founder Elon Musk explained on Twitter that in order to colonize Mars, we would have to support life in glass domes at first before we eventually, terraformed [Mars] to support life, like Earth.

This content is imported from Twitter. You may be able to find the same content in another format, or you may be able to find more information, at their web site.

Musk, as has been well established, wants to realize his dream of making humans a multiplanetary species and build the first colony on Mars by 2050. To make the Red Planet habitable for life, Musk has previously suggested terraforming Mars by nuking the planets ice-capped poles. But now, perhaps after realizing such a plan would require nearly the entire worlds supply of nuclear warheads to accomplish, Musk is taking a more sensible approach to colonization.

You love Elon Musk's crazy ideas. So do we. Let's nerd out over them together.

Musk continued in the same thread:

This may be a good pivot for Musk, because the science isn't exactly on his side. Studies have shown that even with the right firepower, there simply isnt enough of the greenhouse gas carbon dioxide available on Mars to create an atmosphere capable of supporting life on the surface.

This isnt the first time Musk has mentioned using glass domes as habitats on the Red Planet. In a 2016 Reddit AMA, Musk said glass panes with carbon fiber frames could be used to build geodesic domes on the Martian surface, while mining droids could build pressurized caves underground for industrial operations.

More recently, Musk laid out his plans to build a city on Mars in a livestream event last month. He stressed the idea of a Martian colony being fully self-sufficient in case support from mothership Earth would somehow be cut off.

The acid test, really, is, if the ships from Earth stop coming from any reason, does Mars die out? Musk told interviewer Robert Zubrin during the event. For any reason. It could be banal, or it could be nuclear armageddon, he added.

In the interview, Musk claimed a fully self-sustaining city would need around 1 million inhabitants and require 1 million tons of cargo. But if Musk plans to transport that much cargo, hes going to need a bigger ship.

SpaceX is currently developing its next generation of reusable rocket, dubbed the Starship. The fully-reusable spaceship is designed to carry 150 tons or 100 people into orbit and have the capability of refueling in space. Starship uses the powerful Raptor Vacuum engine, which is specifically designed to operate in the vacuum of space and use fuels that can be refined on Mars.

Musk has said one of the first colonization missions to Mars would carry equipment to build a refueling station on the surface, with Starship acting as an initial habitat. Musk claimed in the livestream that the first crewed Starship missions could launch as early as 2026. Although a prototype of the spacecraft recently completed a successful 500-foot hop, the experimental rocket has a history of going boom.

If Musk does accomplish his dream, who can tell what life may be like on Marss first colony? But based on Musks previous sentiments, it may look a lot like the Wild West. When asked in the same Twitter thread about what laws and society might exist on the new Martian colony, Musk replied, Let the Martians decide their own future.

9 of the best board games to play for fans of science and tech – New Scientist

By Dino Motti

Black_Kira/Getty Images

Were living in a golden age for board games. They are experiencing an explosion in popularity as sales have soaredduring covid-19 lockdowns. And as crowdfunding platforms like Kickstarter have helped lower the barrier to entry for new designers and publishers, there is an increasing variety of games to choose from.

Despite being made mainly of cardboard, many new games are complex, memorable and educational experiences on a par with the most technologically advanced computer-based simulations. With historical, political, scientific, linguistic and socio-technological themes, there is something for everyone.

For lovers of nature, ecology and biology, Wingspan by Elizabeth Hargrave is a beautifully presented, non-confrontational game celebrating bird diversity. Players score points for attracting unique species to their reserve. It contains hundreds of beautifully illustrated bird cards with special abilities that synergise as they inhabit a range of environments.

Kim Euker/Stonemaier Games

For a more competitive experience, Dominant Species by Chad Jensen simulates survival of the fittest. A long and strategic game for six players, it sees major animal classes engage in a fierce, adaptive battle for a range of environmental niches to become the most dominant group before the next ice age.

Putting climate change centre stage, CO2Second Chance by Vital Lacerda is a semi-cooperative experience in which players act as the CEOs of energy companies. You compete for market share by trading carbon credits and building greener power plants. Can you solve the worlds climate woes?

If you (unlike me) havent had enough of the coronavirus crisis, then you might like to try Matt Leacocks Pandemic, in which you play as a team battling the spread of diseases across the globe. It is a collaborative game in which players win or lose together. If you want more of this tense, rewarding experience, Pandemic Legacy is well worth a look. As in real-life, choices have permanent effects. The game board and rules irreversibly evolve over the course of 12 months, providing an experience unique to each group of players.

Consumption (not the TB kind) is a game for lockdown pantry planners designed by dietician Karen Knoblaugh. Players shop for food groups, prepare recipes and burn calories. You win by achieving a balanced diet and active lifestyle while minimising food waste.

For space enthusiasts, fledgling astronomers and sci-fi fans, or if you have just had enough of Earth and its infectious diseases, The Search for Planet-X by MatthewOMalleyand BenRossetoffers a deductive puzzle in which you are astronomers searching for a mysterious planet at the edge of our solar system. Players survey the sky, make observations, publish theories and take notes on each others moves.

For flight engineers, Phil Eklunds High Frontier offers a detailed simulation of mission planning and execution for space enterprise. Boasting the most complete representation of the solar system in any game, this is for those unafraid of calculations and complex plans. Then you have Jacob Fryxelius Terraforming Mars, a strategic game that has gathered a cult following. You take on the role of space entrepreneurs, racing to make the Red Planet inhabitable, deploying space elevators, aerobraking ammonia asteroids and introducing rock-eating bacteria.

And if you cant meet other people because of coronavirus regulations, but still want to play board games, check out the huge range of titles available on Tabletop Simulatoron Steam.

Kim Stanley Robinson: The Science Fiction of Right Now – Highsnobiety

This story appears in HIGHTech, A Magazine by Highsnobiety. Our new issue, presented by Samsung, includes exclusive pages of interviews, shoots, merch, gadgets, technical gear and more. Order a copy here.

Kim Stanley Robinson is probably the greatest living science fiction writer, though its unlikely hed want to compare himself with his peers. In his Mars trilogy of novels, published in the 1990s, he introduced popular culture to the idea of terraforming: transforming other planets to make them habitable. Science fiction, although often set in the future, is generally a reflection on the present, and this is especially true in Robinsons work. Because while terraforming Mars may be a long way off, we as a society are now urgently considering planetary transformation on Earth via climate change.

Robinsons latest novel, The Ministry for the Future, confronts this topic even more directly. It opens with India suffering a massive heat wave in which millions die. As a result, the country decides to ignore coordinated, international action and deploys a dangerous, solar radiation management technology in a bid to save itself from the lethal heat. It works but now a new ministry must advocate on behalf of future generations to stop further risky, mega-tech interventions to bring Earths temperature under control.

Robinson is often praised for the well-researched, hard science in his novels, but also for the depth and believability of his characters. Many writers can do one. Not so many can do both. A lifelong leftist, nature-lover, and California hippy whose visionary works tear a hole through the boring dystopias that dominate Hollywood, Robinson recently responded to our Rorschach test of subjects to pontificate on: from Ancient Greek mythology to cryptocurrency to hiking tips.

Utopia is a minor literary genre and also now a necessary concept for guiding us into a good future. It should be understood not as an end-point perfect society and end of history, but rather the name for a good future for human history and Earths biosphere. It will never be secured but is to be thought of as a receding horizon that we always approach and never get to. Also, to the extent that we make a good society, it will be under attack by people who dont like it for one reason or another, and so it will need defending.

So, it is best understood as a name for one particular course for history, one where we are making progress toward a better world for all. That could happen, and hopefully it will; but if it is to happen, we have to have some kind of plan to orient our efforts. Actually, lots of plans are fine they can all be discussed and debated, and add their influence to the progress of real history itself. This is what literary utopias can do: they give us visions to contemplate and judge for their attractiveness and their potential problems.

We need the other animals, and its our moral duty to create space for them on this planet, as has always existed. Were on the brink of creating the sixth great mass extinction event in Earths history, which will hammer humanity as well. To avoid that we have to focus on creating space for other animals, and this is sometimes called rewilding.

Right now about 97 percent of all the meat on the planet is humans and their domestic animals, so the danger is severe. To rewild the biosphere, we need to give room to wild animals, meaning habitats where they can pursue their own lives without interference and prosper. This also implies creating habitat corridors between the areas we reserve for animals, so they can move around in the ways they need to survive over the long haul. All this needs to be arranged and paid for in the human economy and ecology, and indeed the whole point of civilization should be to create a situation in which all the wild animals are doing well.

My home state is a strange place. Its some kind of culmination to American history, in that many people kept moving west until they had to stop. And where they stopped was a very unusual landscape with a great amount and variety of terrains and climates. A biological hot spot, even though it doesnt have much water compared to places with more rainfall and what would be needed to supply the needs of its almost 40 million people. Its water is distributed around the state by way of a system, so you could say its a terraformed space.

Add to that a very strange history, including the original gold rush, Hollywoods movie industry, and Silicon Valleys computer industry these combine to make for a freakish place, a magical name and idea in world history. Possibly all these blessings add up to a curse, but at least California will always have its Sierra Nevada, one of the great mountain ranges of the world and one of my favorite places to be.

For hiking, you need good shoes. For backpacking over multiple days, you need a light backpack, and in it a tent (really a tarp), sleeping bag, ground pad, clothing, and food. Walking poles help with walking and can be used as tent poles at night. All these items have been made in lighter and lighter forms for the sake of people walking from Mexico to Canada in a single summer, so an ordinary backpacker can take advantage of these technological innovations and hike with no more than 20 pounds of gear and food on their back for a weeks trip. This is a great thing for aging backpackers.

This has become a word for things we dont like to think about doing. By definition, geoengineering has become bad. So, maybe we need another word now for deliberate interventions in the Earth system to dodge the mass extinction event that we are now starting. It wont be just solar radiation management, which is what people usually think of when the word is used, but also anything done on a large scale to make a significant difference in the atmosphere, ocean, or land surfaces, with the intent to decarbonize the atmosphere and reduce the damage of our current civilization.

So, this means actions somewhat similar to what we usually think of when this word is used, up to and including solar radiation management, but also biological interventions like reforestation, biochar, kelp farming, regenerative agriculture, and so on; then also, technological innovations like direct air capture (DAC) of CO2 from the atmosphere, and the removal of water from underneath the accelerating glaciers in Antarctica and Greenland.

And to these we should also add social innovations such as womens rights, which reduces the birth rate and thus the human impact on the biosphere, or sharply progressive taxation and a strong social safety net, which reduces the excessive impacts of the richest and poorest humans. All these strategies need to be pursued concurrently and to the fullest extent in order to give us the best chance possible of avoiding biospheric catastrophe.

Gaia was an Earth goddess in ancient Greek mythology, or an image of Earth itself as a kind of divine figure. In the original Greek she was not just a mother figure providing all the necessities of life, but a capricious and dangerous character, prone to fits of anger and a divinity not to be ignored or disrespected. When we use her in the modern world as an image for Earth as some kind of larger symbiotic life form, a supra-organism of which we are a small part, this is somewhat abstract and hypothetical. If all the creatures living on Earth are seen as combining to make up some larger life form, with the individual lives serving as something like cells or organs in a larger body, then Gaia is maybe real, by that definition, but too large and amorphous to tell us much that is useful.

What we need to do to make the idea of Gaia useful now is to acknowledge that there are some collective creatures that are real but not conscious, and need our imaginative life to make it real and to provide its agency. When we have that image of Gaia, well have the basis for a religion based on reverence for the planet we live on. It will be a kind of Earth religion, but with a connection to our present moment that hopefully will make the idea powerful to us again.

This is the name of my most recent novel. It tells the fictional story of the next 30 years of history, in which the danger of a mass extinction event and human catastrophe is dodged by way of a complete effort on the part of many parts of civilization. One aspect of this effort is an organization created under the auspices of the Paris Agreement to represent the interests of the people of the future, also all the people who cant represent or speak for themselves in the worlds legal systems, which is to say, all the wild animals and ecospheres. This is, of course, a problematic project and entails a lot of efforts by a lot of people, working against a lot of resistance. The story, like the ministry, is based in Zrich, Switzerland, and it uses a lot of literary forms to tell the story, including many fictional eyewitness accounts from participants in events of all kinds.

This is an idea being advanced by some economists that complements the idea of a carbon tax being levied against all burning of carbon into the atmosphere. The carbon coin would be paid out to all methods of sequestering carbon in the atmosphere back into the ground. It would be convertible with other currencies and provide a kind of carrot to the stick of carbon taxes.

Paying for the work of carbon sequestration is crucial to sustain the massive amount of work and sheer human time it will take to get the job done fast enough. Much of this effort wont make a profit in the capitalist system, and so a kind of quantitative easing, or directed government payments for doing the necessary things, is desperately needed. We cant just declare the end of the world because we cant afford to save it. We need to find ways to pay for this necessary work. The carbon coin is part of that.

The Green New Deals being put on the table around the world are associated with the carbon coin they refer to government plans to invest in sustainability itself. The pandemic of 2020 has caused an economic depression that has been responded to by various governmental interventions, including quantitative easing, which is to say the creation of money by the central banks of many countries.

More and more these infusions of new money by governments have been targeted to particular purposes rather than just given to private banks. When the original spending of this new money is targeted to environmental causes and the fight against climate change, these are called Green New Deals in part to remind people of the New Deal of the 1930s and its success in coping with the Great Depression. In the EU, the recovery from the pandemic is being coordinated with this necessary environmental work, and one wing of the American Democratic Party has proposed the same kind of thing be done in the US. Its a good idea.

The Expanse Season 4 Recap: Ilus, the Ring Gates and the Cliffhanger Ending – Den of Geek

Not all Belters are on board with this new paradigm, perceiving it as selling out; a capitulation to those who would still demean and exploit them. Marco Inaros (Keon Alexander) is the most vocal and militant voice of opposition. Marco is Naomi Nagatas (Dominique Tipper) ex-beau and father of their child, Filip (Jasai Chase Owens), and while these days he styles himself a freedom fighter, it wasnt always thus. When he was with Naomi, he tricked her into writing code that he claimed would merely disable other ships, allowing their faction to come to the rescue and extort payment for their time and trouble. However, Marco used the code to overload the reactor of a docked ship, killing hundreds of people. When the distraught and guilt-ridden Naomi left the faction she was prevented from taking their son, Filip.

Marco is apprehended by Drummer and Ashford for his part in capturing the UNN colony ship Soujourner and executing its crew. While aboard the Behemoth, Marco tries to win Ashford over to his world view, reminding him that the Belt will suffer a terminal decline of profit and influence owing to the exodus, and, besides, very few Belters, due to their space-bound physiology, will be able to take advantage of the brave new worlds beyond the ring gates. The heads of the various OPA factions assemble to decide whether or not Marco should be spaced (ejected into space sans suit) for breaking the fragile truce between the inner and outer planets. Its Drummer who breaks the tie, reasoning that killing Marco would make him a martyr, and propel into action those factions loyal to his cause.

On Earth, Avasarala faces a leadership challenge from Nancy Gao (Lily Gao) who, in contrast to the incumbent, is a fierce advocate for embracing the change, opportunity and adventure that the ring gates represent. Avasaralas campaign takes its toll on her ethics and her personal life, especially her marriage. She resorts to smears against Gao, and isnt above attempting to use the problems on Ilus to her advantage.

OPA bigwig Fred Johnson (Chad L. Coleman) reveals Marcos location to Avasarala, who wastes no time in dispatching a team of marines to the Pizzouza spacecraft to extract him. Marco, however, isnt on board, and the resulting firefight between marines and Belters results in grave loss of life. The fallout critically damages Avasaralas image, reputation and election chances, and moreover plays right into Marcos hands.

Fred Johnson visits the Behemoth, receiving from Drummer both a punch in the face and news of her resignation. Ashford vows to track down and kill Marco and wants Drummer to accompany him, but she declines on the grounds that shes sick of politics and its machinations.

We asked Kim Stanley Robinson: Can science fiction save us? – TheWestNews

What does the future hold? In our new series Imagining the Next Future, Polygon explores the new era of science fiction in movies, books, TV, games, and beyond to see how storytellers and innovators are imagining the next 10, 20, 50, or 100 years during a moment of extreme uncertainty. Follow along as we deep dive into the great unknown.

We asked Kim Stanley Robinson: Can science fiction save us?can map a positive future in an unrelentingly negative era, we naturally started thinking about Kim Stanley Robinson. The novelist the L.A. Times Review of Books called our last great utopian visionary and the New Yorker called one of the most important political writers working in America today, Robinson is known specifically for dense, thoughtful novels about where Earth might go based on science and culture today. The trilogy hes best known for Red Mars, Green Mars, and Blue Mars uses terraforming in space as a way to raise the issue of reclaiming our own Earthly environment, and to consider how we interact with it. His 2017 novel New York 2140 is set in a future New York thats flooded due to climate change, and like many of his other books, it presents utopian alternatives to capitalism.

And his latest book, The Ministry for the Future, again models a series of attempts to contain and control climate change, in a sprawling story that acknowledges personal and public problems with systemic change, but still comes across as more hopeful than pessimistic. Polygon spoke with Robinson by phone to discuss the problems with science fiction utopias, how theyre sparked real change in the past, and how we use science fiction in everyday thinking.

Can science fiction save us in our present political and cultural circumstances? Is it a useful teaching tool to help us think about how to solve our present problems, or model better ways of living?

Well, its the latter, for sure. Whether its the former depends on whether we pay attention. But let me answer a little more at length.

If you think of science fiction as just a kind of modeling exercise, everybody is a science fiction writer in their own lives. You make plans based on modeling in your mind. When youre feeling hopeful, you have a kind of utopian plan: if you do these things, youll get to a good place. And then when youre afraid, you have these worries that if you do these things, youll get to a bad place. So the fundamental exercise of science fiction is a very natural human thing. And then when it gets written down in long narrative forms, like science fiction novels, everybody recognizes the exercises involved there. Although when I say that, I realize that, actually, lots of people dont like to read science fiction, so theyre not recognizing the way books are the same as what they do for their own lives. Thats surprising to me, but it happens a lot.

Anyway, science fiction is a modeling exercise where all the science fiction put together, especially all the near-future visions, they range from totally horrible to perhaps quite nice. Its heavier-weighted at the disaster end than at the utopian end, maybe because its easier, or maybe because its more shockingly interesting to read. Its not like going to town meetings and reading blueprints for plumbing facilities. The utopian end of science fiction has a reputation for being a dull, eat-your-greens type fiction, so theres less of it compared to the disaster stuff. But there is both. And if you read a lot of it, one hopes youre prepared for anything.

[quads id=3]

That isnt 100% true, but youre maybe better prepared than if you hadnt read it. In that sense, I think science fiction could be a great teaching tool for people. You cant read all science fiction, and if youre reading nothing but space opera, none of this would obtain. Because the problems of spaceships flying faster than light across the galaxy are not always immediately applicable to the situation were in here on Earth. So its a specific wing of science fiction Im talking about that could be helpful if people read it.

With a book like New York 2140, are you actively out to teach people? To model a positivist future where people can make real individual change?

Yeah, I am! I consider my novels, amongst many other things, to be my political activism. Im interested in portraying futures where there are more cooperative, altruistic, post-capitalist systems that are working well. I try to model them on things already going on in this world that seem to be better to me than the dominant global neoliberal order. And then pretend that those small communal efforts around the world intensify and take over, so their emergence signals an emerging world order that would work better with reconciling humanity and the biosphere. Because we have to come into a balance with our biosphere, or else were in terrible trouble.

I do that on purpose in the New York novel, very explicitly so. I was trying to work on how to make people think about how finance works, how it can be made to work for us, rather than for extracting our money for the 1%. So yeah, for sure.

Youre celebrated for a level of research and realism in your novels, regardless of whether theyre near-future or set in space. Is part of the urge for that level of realism just that you cant model a real and inspiring future if youre not working from real facts?

Thats one way of putting it, and I would agree with that. But what Id also say is that, along with thinking of my novels as my political activism, Im just an art-for-arts-sake kind of English-major guy. I would like to write good novels. And thats my overriding consideration. And its a kind of life-quest thing, or a religious quest. What makes a good novel? When I think about them as a reader, what I like in a novel is that kind of dense feeling of reality, where you read it and go, Yeah, thats the way life really is.

If you set novels in the future, like I seem compelled to do, and you want your readers to say, Yeah, thats the way life really is, you have to overcompensate a little bit. I used to call it cardboard sets. You know how you look at the TV Star Trek from the 1960s, and you can see that the spaceships bridge was made of cardboard and plywood? Science fiction, to me, has too many cardboard sets and backdrops, and it reduces your ability to take the story in as something serious and moving. So in other words, to make a good novel, and yet also have the story set in the feature, which is a bit of a crazy thing, I had to overcompensate and try to make them even more realistic than your ordinary realist novel.

So then they become a little fact-heavy. Ive had to work against being too ponderous, or overcompensating too far. But yeah, thats the reason Ive gotten caught up, in its almost like Im in a double bind. Im trying to do two things at once that dont match up very well. And it causes the distortions in my books that make them weird. Ive long since reconciled myself to that. Its actually a good thing to be different. And its a good thing to have weird novels, because there are too many novels that arent weird enough. Theyre too easy and too ordinary, and they slip through your mind, and then youve forgotten them and the writer. So to be a little bizarre and obdurate, so its actually a bit of work, and even sometimes irritating? Well, thats part of the experience of reading one of my novels, and afterward, you remember it better. [Laughs]

[quads id=4]

At least I hope so. I mean, thats a good way of looking at it. You know, they are very controversial books. Im highly aware that I get a high positive and a high negative. There are a lot of people who think Im just simply inept, because I dont do it like other people do. And Im not very fast-paced, although I would like to be. Id like to show people are wrong. I have fast-paced sections in my book all the time. But the ultimate effect is that my books are these big monsters.

The LA Review of Books referred to you as our last great utopian visionary. What do you think of that title, or at least the utopian visionary part?

I think thats fine. Ive rolled the dice toward doing utopian fiction. There isnt very much of it the canon of utopias could be listed on your fingers and toes. And yet I think theyre very valuable. Occasionally, they have effects in the real world. Edward Bellamys Looking Backward from 1888 was a big part of the progressive movement 120 years ago. H.G. Wells utopian novels had a huge impact on the Bretton Woods agreement and the settlements after World War II. A good utopian novel can, a generation later, or even a few years later, have an impact on how people think the future should go.

I felt a deep kinship and love for Ursula K. Le Guin and Iain Banks, these two great utopian writers. Theyve died, and I do feel a bit lonely for my own generation. But I also see a lot of young writers coming up who call themselves solarpunk, or hopepunk, or the new utopians, and whatnot. Theyre forming schools, theyre trying to get enthusiastic about improvising our way to a green future. I think theyre utopian, but perhaps a little bit outdated or scared by the term utopia, because its so often used as a weapon to mean unrealistic and never going to happen. So they make up different names. Im glad to see these. I dont think utopian fiction will ever go away. Its like a necessary blueprint for thinking our way forward. So it seems like its a good time for utopian fiction. Im sad at losing colleagues I loved, but Im encouraged at the way the genre itself is ratcheting its way back into peoples attention.

Its surprising how many classic novels described as utopian fiction are actually disguised as dystopian novels.

This is worth talking about! In the Greimas rectangle, theres the thing thats not you, and theres the thing thats against you. These are not the same. In that model, the opposite of utopia is dystopia. But the thing against you is anti-utopia. What that model is saying is, if you try to get to utopia, it would necessarily be bad. So its against the idea of utopia itself. Dystopian fiction isnt against the idea of utopia. Its just saying, Oh, we tried, and we lost. But anti-utopian ideas say that trying to make utopias necessarily rebound, and boomerang into disaster.

So for example, 1984 is a dystopia. Big Brother is not trying to make you happy. That government is putting its boot on your neck. But Brave New World is the great anti-utopian novel, where they try to make everybody happy, so they drug them and electroshock them, and then everybodys supposed to be happy, and it doesnt work. Those two very, very famous novels service, the great dystopia, and the great anti-utopia. And the fourth term in the rectangle this comes out of Fredric Jamesons Marxist literary criticism would be anti-anti-utopian. That gets super mysterious, but it just refers to insisting that its possible to make a better world. So thats the mysterious fourth term in that particular rectangle. I am anti-anti-utopian, but Im also utopian, which is a little more obvious.

Yeah! Yeah, it is!

Supposedly utopian fiction cant have a story, because it cant have conflicts or imperfections. How have you approached that problem as youre thinking about all this philosophically?

Yes, sure. I think there are some. One strategy I used in Pacific Edge is, you show that in a utopia, its still possible to be extremely unhappy. In a utopia, theres still A falls in love with B, whos in love with C, whos in love with A, and theyre all miserable. Or A is in love with B, and then he dies. Utopia does not guarantee human happiness. It just takes away unnecessary suffering by way of political oppression.

Another way is to define utopia as not a perfect end-state society. Thats impossible anyway. You define it as a progressive movement in history, with each generation doing better than the generation before, in substantial ways, in terms of equality, justice, and sustainability. Its a process, not a product. So utopia is just a name for one kind of history. I do that a lot. Lastly, Iain Banks was great at this. In his space-opera novels, there was a post-scarcity galactic utopia, but its always under assault by forces that dont like it. He was one of the greatest writers of my generation, in so many ways, but especially in terms of stage business and exciting plots, Iain was the master. His utopian society always had to defend itself, sometimes quite violently. So the defense of utopia becomes like a war zone, and suddenly youre back to war novels. And then the utopia sits there as a kind of a given, but it has to be defended. Thats a great strategy that I havent used as much as Iain.

I learned from him, and I learned from Le Guin. She always went right to the heart of the contradictions: if everybodys free to do what they want, who takes out the trash? What happens when theres a drought? Is there a police force? If there isnt, how do you control a violent person? In The dispossessed, she basically went to every one of the problems utopia would have in terms of contradiction, and dramatized that. I learned a lot from her, too.

What else interests you in science fiction right now? Whats going on that you find intriguing or inspiring or enlightening?

I like a lot of feminist science fiction, from the women who are basically my generation of writers. Theyre still doing good work. I like the new, young solar utopians. I like British science fiction. Im a little hampered here, because theres way more going on than Ive had a chance to see. I read my friends, who tend to be my age, I read interesting new things to try to keep track of stuff. I see utopians like Cory Doctorow, or leftist science fiction thats political and intense. And that and the leftist feminist wing, I think, is strong right now in community.

[quads id=3]

People see science fiction as a way to write out your social, political, and personal hopes. I think its at a pretty healthy status right now. Science fiction seems almost central to the culture in a way that wasnt when I was young. Everybodys aware of it. Theres no prejudice against it. Most of thats gone away. So I like the feeling of it being an aspect of the mainstream. Im a public intellectual and a political figure Im really just a novelist and a science fiction writer, but because this culture now takes science fiction seriously, that means theyre taking me seriously.

When you bring up women writers of your age that you particularly admire, who are you thinking of?

Karen Fowler. Molly Gloss. Eleanor Arnason. Kathy Goonan. Pat Murphy. Lisa Goldstein. Gwyneth Jones and Justina Robson in England. The list could go on and on. A thing happened in academia and in culture at large Le Guin, Joanna Russ, and James Tiptree, Jr., [the pseudonym of] Alice Sheldon, they took all the attention. People like to reduce their attention to a few charismatic figures and forget about the rest. Academic critics are like that too, creating their canon. So the Le Guin/Russ/Tiptree combine sort of represented feminist science fiction as if it was the only thing there. And this whole cohort of women my age, who are just a little younger than Le Guin/Russ/Tiptree, they got sidelined by academia, and had a tough time catching readership, even people like Sheri Tepper, or Suzy McKee Charnas. Names will keep coming to me.

They are all great writers, and they havent gotten the academic attention they deserve, because academics tend to flock to what everybody else has already read, so theres a mutual shared understanding of what youre talking about. So theres a natural canonization is a weird increasing-returns situation, where early attention to someone like Le Guin as great a figure as she is, she wasnt writing novels that were any more distinctive than, say, Suzy McKee Charnas.

Ive been a beneficiary of a very much slower, smaller increase in returns. A lot of writers of my generation are very fine writers, so I see it happening all over. Also, cyberpunk came in in the 80s and said, Oh, everything going on in the 70s was junk, and that included all these women science fiction writers who got erased by a publicity-hound machine that wasnt interested in feminism, per se. So the 80s were bad in many ways, politically, and that was one of them.

Where would you like to see science fiction go from here?

Thats a good question, because Im feeling kind of mystified. If science fiction is mainstream, and its the realistic fiction of our time, what now? The future seems to be getting really hard to foresee or predict. The bottom line is, you could you could have a horrific mass extinction event next, or a superb Golden Age. It isnt like were on any obvious trajectory.

Heres what I could say: Theres lots of different kinds of science fiction. Theres the kind that is a disguised version of today. Theres space opera that takes us off into the galaxy, and its millions of years from now, and its basically magic. And then theres that middle time thats talking about various futures about 100 years out, maybe 200 years out at the most. I call it future history, and thats been my zone. And its relatively depopulated, compared to the other two. Ive done a lot of near-future, day-after-tomorrow, science fiction really talking about right now, like the New York novel. I would like to see that zone become really vibrant, so people begin to see how important what we do now is for determining the next couple hundred years, and that huge spread of possibility. So I guess I would just say more future history.

Longtime Literature Professor, Noted Poet Begins Next Chapter with Retirement – University of Texas at Dallas

University of Texas at Dallas professor Dr. Frederick Turner, who over the past 50 years has won numerous literary awards, published dozens of books, touched the lives of hundreds of students, and even been quoted in The American Heritage Dictionary of the English Language, retired from teaching Sept. 1.

Dr. Frederick Turner

Turner, the Founders Professor of literature and creative writing, is described by many as a Renaissance scholar, with interests that span poetry and literature to neuroscience and psychology.

He could not have fit more seamlessly into the vision that started UTDallas that is, seeing linkages across disciplines, seeing that the more interesting the problem, the more it demanded seeking multiple modes of understanding it, said Dr. Dennis Kratz, senior associate provost, director of the Center for Asian Studies, and the Ignacy and Celina Rockover Professor. He has been adventurous and willing to address the large ideas underlying the specific concepts that too many academics limit themselves to.

Dr. Nils Roemer, interim dean of the School of Arts and Humanities, director of the Ackerman Center for Holocaust Studies, and the Stan and Barbara Rabin Professor in Holocaust Studies, described Turner as an unbound professor who will delve into anything to follow his curiosity.

For Fred, its all connected science, nature, poetry and theres no real separation. These types of scholars are not governed by boundaries or disciplines or a sense of respective expertise. If theres something that interests them something beautiful and aesthetic they are there, Roemer said.

He has been adventurous and willing to address the large ideas underlying the specific concepts that too many academics limit themselves to.

Dr. Dennis Kratz, senior associate provost, director of the Center for Asian Studies, and the Ignacy and Celina Rockover Professor

The son of an anthropologist, Turner grew up in Zambia where he learned through correspondence courses. Eventually, he earned his bachelors and masters degrees at the University of Oxford, where he also earned a BLitt (no longer given), which is a terminal degree at the PhD level.

Turner came to UTDallas in 1985 after beginning his teaching career in 1967 at the University of California, Santa Barbara. Turner taught a range of subjects, including Shakespeare, Renaissance studies and performance studies, but writing and literature always remained the heart of his work.

Fundamentally, Im a poet, he said. I had my sense of poetic vocation when I was about 10 years old. And although I love teaching and love being a scholar, those were essentially ways of supporting my writing habit. Poets need patrons, and probably the best patron you can have is yourself.

Turner is a winner of the Miln Fst Prize (Hungarys highest literary honor), the Levinson Prize for poetry, the Dallas Chapter Golden Pen Award, The Missouri Review essay prize, the David Robert Poetry prize, the Gjenima Prize, and several other literary, artistic and academic honors. He has participated in literary and TV projects that have won the Independent Book Publishers Association Benjamin Franklin Award and an Emmy, respectively. He is a fellow of the Texas Institute of Letters. Turners Genesis: An Epic Poem, published in 1988, was the first major work of poetry that addressed the idea of terraforming Mars.

Dr. Frederick Turner (right) and Dr. Zsuzsanna Ozsvth read testimonies written by concentration camp prisoners during a special Holocaust event in March 2018. Turner and Ozsvth, who also retired recently, collaborated on a number of writings and events, particularly translation projects.

He has published nearly 50 books, which include collections of poetry, book-length poems, literary criticism, cultural criticism and literary translations. Most of the translation books were done with his longtime collaborator, Dr. Zsuzsanna Ozsvth, UTDallas professor of literature and history, who also retired recently. The two plan to continue their weekly meetings and translation collaboration. Turner called Ozsvth his closest non-family friend.

Roemer said Turner has been popular even life-changing among students.

You have normal professors, and you have professors with whom students form very deep, long-lasting relationships. Fred is among those professors who have been very transformative to many, many students, Roemer said.

Even though Turner is retiring from teaching, he said he will continue to contribute to the University through talks, advice and institutional memory. He plans to spend most of his time diving deeper into his writing.

Dr. Nils Roemer, interim dean of the School of Arts and Humanities

For Fred, retirement is about finally being able to do all the other things he wants to do particularly writing, Roemer said. His writing was part of UTDallas, but it also extended beyond that, to the world, which is why I think his teaching is the biggest mark that he is leaving behind.

Turner said he hopes UTDallas will continue to focus on its interdisciplinary nature.

The University, of course, has big demands to shine in particular niches or pigeonholes, and thats fine, he said. But I think the soul of the University is in what happens in between the pigeonholes. And I hope we continue with that.

Destination Red Planet: For space buffs, this summer has brought multiple Mars bound space launches – The Times of India Blog

Mars is back in the news. In July, three countries launched missions to Mars. The first was the United Arab Emirates, which sent its Hope orbiter on board a Japanese rocket on July 19; Chinas Tianwen-1 mission followed on July 23; and, finally, the United States launched NASAs Perseverance rover on July 30. A fourth mission, by the European Space Agency and Russia, was postponed to 2022.

It might seem like a race is on to reach the Red Planet, akin to the race to the Moon in the 1960s. But the explanation is a bit more mundane: every 26 months, the Earth and Mars are closest together. This offers a brief window for a quick journey to Mars. If you miss the window, you have to wait another 26 months which is what happened to the ESA/ Russia mission.

Mars has always loomed large in our imagination, and science fiction writers have been depicting voyages to the red planet for centuries. In 1887, the Italian astronomer Giovanni Schiaparelli undertook detailed telescopic observations of Mars and observed a dense network of features on the surface. He called them canali which stands for channels in Italian, implying narrow and long depressions. However, that got mistranslated into English as canals, giving rise to immense speculation and an entire corpus of science fiction, the most famous of which is HG Wells The War of the Worlds.

Theres reason to be fascinated by Mars. The planet has numerous features in common with Earth. Although smaller than Earth, it has a similar rocky composition and marked seasons. NASA missions over the decades have made it clear that an environment different from the cold, dry world we see today once existed on Mars. Liquid water flowed on the Martian surface in the past: there are vast dry gorges and canyons etched by water and ice (Schiaparellis channels). Some scientists think Mars might have harboured life not the advanced aliens of science fiction, but more mundane bacterial life that might today be extinct.

In 2007, when the world celebrated the 50th anniversary of Sputnik, Id asked Arthur C Clarke, famous science fiction writer and visionary, about whether human beings would set foot on Mars soon. During my lifetime, Ive been lucky enough to see our knowledge of Mars advance from almost complete ignorance worse than that, misleading fantasy to a real understanding of its geography and climate, he had replied. He had even gone on to talk about what would make Mars habitable for humans since now we have fairly accurate maps of the Red Planet, and can imagine how it might be modified terraformed to make it nearer to our hearts desire.

In fact, terraforming Mars has been advocated in recent years by Mars enthusiasts and would-be colonisers such as Elon Musk, who has publicly said he wants to die on Mars (although not just on impact). Terraforming or earthforming is a Herculean feat of planet-wide engineering that will change the Martian atmosphere and allow humans to make uninhabitable Mars into a planet fit for natural life. While terraforming has a lot of followers, some recent studies have said it might actually not be possible on the scale humans would need to survive on Mars.

But first humans have to get there. And, hopefully, return. To do that, we would need large, reusable rockets and a plan for humans to be able to survive the entire duration of the roundtrip, which is going to be a few years. In 2010, US President Barack Obama predicted that a crewed mission will orbit Mars by 2030, followed by a landing soon after. President Trump signed an order directing NASA to send astronauts to Mars in 2033.

Russia has also publicly announced intentions to send humans to Mars in the 2040-2045 time frame, and the ESA wants to do so as well. Nations like India, China and Japan have already attempted uncrewed Mars orbiters. Indias Mangalyaan mission was successful, and started orbiting Mars in 2014, but China and Japan have both failed to get their missions into Mars orbit. China is now trying again, and the UAE has become the first Arab country to attempt an interplanetary mission.

Its well documented by now that missions to space are a great catalyst for a nations advance in science and engineering. Many technologies we now take for granted wireless headsets, electrolytic water purification systems, camera phones, CAT scans, to name a few owe a lot to the Apollo missions to the Moon. In fact, some argue that the investment by the US government in the Moon race led to its current science leadership.

Whether geopolitics and rivalries between different nations will speed up the timeline to Mars remains to be seen. Competition can only be healthy, and the world is likely to benefit from the fallout. Like the Moon missions, missions to Mars will probably produce technologies that will benefit humans on Earth as well.

In fact, the question is not if we humans will reach Mars but when. Clarke, who more than most 20th century visionaries had the knack of being proved right, had quipped back in 2007, I have sometimes wondered if there might be a committee to protect the Martian wilderness in the 22nd century!

Meanwhile, the Red Planet continues to yield new surprises. Just this week, NASA announced that its Mars Reconnaissance Orbiter took pictures of baffling ridges on the surface of the planet. Some of us will probably witness a Mars landing in our lifetimes. We will certainly know by then if life ever existed on Mars, even if it were a primitive, bacterial kind. Should the answer be yes, it would be another profound milestone in our evolving understanding of humanitys place in the universe, the scientific revolution that started with Nicolaus Copernicus and Galileo Galilei.

Cool! Heres how Venus would look as a water world – EarthSky

Its hot enough on the surface of Venus to melt lead. There are also crushing surface pressures and clouds full of sulfuric acid. So theres no water on the surface of Venus today. This planet orbiting next-inward from Earth around the sun is one of the most inhospitable places in our solar system. But scientists think that, a few billion years ago, Venus might have had oceans, perhaps much like those on Earth. Venus might once have been habitable. Even now, some have suggested terraforming Venus, so that it could become a water world once again in the future. What would Venus look like with water? Reddit user Dragonite-2 has created a map, based on spacecraft data about Venus terrain, and posted it to the MapPorn subreddit. It portrays Venus if it were terraformed to become a more Earth-like world, with a similar amount of water to Earth.

The map has now gone viral.

How accurate is it? And what does it show?

Venus is covered with dense clouds. So we cant see its surface. But radar from spacecraft orbiting this world, or (in the early days) from Earth can penetrate the planets clouds and has let scientists make maps of the highs and lows on Venus surface. Thats why Venus has a known topography, which Dragonite-2 used to create his map of Venus as a water world. Radar images show us Venus mountain ranges, volcanoes, quasi-continental formations and other, flatter regions.

Thus, weve known and now Dragonite-2 has helped us see that if Venus had an Earth-like quantity of water, it would have one large continent in its northern hemisphere. Scientists have named this continent already; they call it Ishtar Terra. Its about the size of Australia. The highest point on Venus, the mountain Maxwell Montes, is located on Ishtar Terra. Theres also a second large continent which scientists call Aphrodite Terra located along the equator of Venus. Its the size of South America (if South America were stretched out along Earths equator, instead of running perpendicular to it). Dragonite-2s map also illustrates smaller continents and islands that would be scattered throughout Venus global oceans, if Venus were a water world.

Dragonite-2s map posted to Reddit is based on spacecraft data. Most of our information about what lies beneath the dense clouds of Venus was obtained by the Soviet space probe missions Venera 15 and 16 and by the American Pioneer Venus and Magellan spacecraft during the period 1978 to 1994. Today we have good information about 98% of the surface of Venus, according to this page from ESO. This map comes from NOAAs Science on a Sphere. Its a compilation of Venus radar data, showing Venus topography as its known today. NOAA wrote: Most of Venus appears to be covered with gently rolling plains. Two areas rise up above the rest of the surface and are referred to as continents.'

Writing in Inverse on August 29, 2020, Mike Brown described the new Venus-as-water-world map. He quoted an associate professor of planetary sciences at North Carolina State University Paul Byrne who told Brown that, in one sense, the map is fairly accurate:

in that someone has taken the real-world digital elevation model for Venus and added a sea level to it.

I dont know how realistic the if Venus had as much water as Earth part is, but Im guessing that whoever made this map picked an average ocean depth for Earth and flooded the Venus topography to that same depth.

However, as Byrne also noted to Brown, the surface would look quite different after erosion by rainfall, rivers and lakes. The map portrays Venus surface as-is, without plate tectonics. But a planet with oceans likely would have plate tectonics the gradual movement of land plates on the planets crust, relative to one another just as Earth does.

And that movement of crustal plates would, of course, affect the configuration of continents and islands.

Venus as seen in enhanced color by Japans Akatsuki spacecraft. Its surface cannot be seen with the eye alone. Its completely covered with dense clouds. Theres a wonderful article about real images of Venus via Japans Akatsuki spacecraft, at the Planetary Society blog. Akatsuki began orbiting Venus in 2015. The images were put through special processing and released in 2018.

Artists concept of what a terraformed Venus might look like, with Earth-like oceans, continents and clouds. Image via Ittiz/ Wikimedia Commons.

But, of course, in another sense, the map of Venus as a water world doesnt compute under current real-world conditions. As planetary scientist Byrne noted in the Inverse article:

In reality, its not remotely realistic.

Thats because of the extreme conditions that exist on Venus today. A watery ocean cant exist on a world thats hot enough to melt lead. So the map isnt accurate in terms of the real planet Venus now. And now is what this map shows. See the contradiction?

Still, Dragonite-2s map helps us use our imaginations and cast our minds back in time or forward into the future when, according to some visionaries, Venus might be a very different place. Byrne was speaking of the past Venus when he said:

Although a Venus with oceans wouldnt look much like the Reddit image, it is fun to think about what a blue Venus might once have looked like, and why its climate turned into the hellish world it is today.

And we can imagine Venus as a terraformed world, purposely made to be more habitable and Earth-like again. This is a well-known concept for Mars, to transform the dry, cold planet back into a habitable one. Despite the fact that Mars is the most Earthlike world in our solar system, terraforming Mars would be difficult, according to most experts.

But terraforming Venus a world the same size and density as Earth, but not remotely like Earth on its surface would be even more difficult.

That hasnt stopped some people from thinking about it, though. The famed astronomer Carl Sagan was one of the first to propose ways to terraform Venus, back in 1961. Sagan had suggested seeding Venus clouds with algae; later, it was determined that wouldnt work because the atmosphere was found to be too thick. Astronomer Geoffrey Landis mentioned Sagans ideas, and the history of terraforming in general, in a paper from 2011.

Below is a short video animation depicting how the surface of Venus might look during a gradual transformation back into a water world:

Of course, the biggest hurdle in terraforming Venus would be in trying to reverse the runaway greenhouse effect that caused the planet to heat up to the extreme temperatures we see today. That wouldnt be easy. It would require huge amounts of energy and advanced technology. But a terraformed Venus might have some advantages over a terraformed Mars, according to Paul Byrne. As Byrne points out, Venus is almost the same size as Earth, with similar gravity, and it might be easier to remove carbon dioxide which makes up most of the planets atmosphere and causes the greenhouse effect from its atmosphere to cool the planet, than to add gases to Mars thin atmosphere to warm it. Byrne commented:

If we were to terraform anywhere, then Id pick Venus over Mars. But, to be clear: its going to be orders of magnitude more achievable to stop f%#&ing up our own climate here on Earth than trying to make anywhere else even remotely habitable for humans.

Good point.

So while Dragonite-2s map in Reddit might not be all that accurate according to scientists it does give us a reason to think. It provides an interesting glimpse at Venus as weve never known it, but which might have existed in the past. And just maybe it gives us a vision a world that might exist again in the future.

Not ready to stop thinking about maps and worlds made habitable via terraforming? Dragonite-2 posted another imaginary water-world map on the subreddit MapPorn, a few days after the Venus map. Its shared below. It shows what Earths moon would look like, if it were covered with water. Enjoy!

Don’t ignore Venus Earth’s twin hides surprising opportunities (op-ed) – Space.com

The planet Venus is fascinating, terrifying, ironic, beautiful, deadly and just possibly alive with organisms.

In many ways, Venus shows us an Earth that could have been; the twin that grew up in a different environment. As one of the few other rocky worlds in our solar system with a thick atmosphere and active volcanoes, Venus can help scientists on Earth learn valuable lessons on global carbon balance, ozone depletion and acid rain. Its wrinkly highlands probably conceal chapters in the origin story of life in the cosmos.

It is faster and easier to get to Venus than Mars. Despite Venus' hellish surface conditions, it may be practical for humans to explore and someday settle the second planet from the sun. Yet no active spacecraft have been sent to its surface since the Soviet Union's Vega 2 mission in June 1985.

As long as there have been human imaginations, Venus has inspired them. A feminine presence in the mythology of ancient Europe and the Middle East, and a masculine spirit in Mesoamerica, the duality of the "Morning/Evening Star" has launched wonder and inquiry about the universe. Interviewing 10 planetary scientists for our documentary film "Venus: Death of a Planet" and its follow-on series "Exploring Venus," we became entranced with the planet's promise. For limited time, Space.com readers can view these films for free at MagellanTV.

Earth and Venus appear to have assembled themselves out of matching materials, very near to one another in the protoplanetary disc of our early solar system. They are nearly identical in mass, gravitation and size; Earth is just 396 miles (638 kilometers) larger in diameter. As of this writing, astronomers have cataloged and confirmed 4,201 exoplanets. But the alien world that most closely resembles Earth's chemical composition, mass, diameter and gravity is actually the planet that orbits nearest to Earth.

"Everything points to Venus and Earth having been twins," planetary scientist David Grinspoon says in our film. "There's a lot of circumstantial evidence that Venus had a more Earthlike environment when it was young. They may have both had warm oceans and all the other conditions necessary for an origin of life at the time when Earth, apparently, had an origin of life."

But not anymore: The Soviet Venera and Vega landers of the 1970s and 1980s recorded temperatures around 864 degrees Fahrenheit (462 degrees Celsius) and pressures equivalent to being submerged 3,051 feet (930 meters) in an ocean on Earth. Studying when and how Venus and Earth diverged so radically from their initial similarities could be essential for sensibly managing our planet in this Anthropocene age.

Venus has been called the poster child for the greenhouse effect. Measurements of the ghastly conditions at its surface have alerted and will continue to inform Earthly climate science. Spoiler Alert: Humans will not succeed in liberating enough carbon to bring about a Venus-like hell on Earth. But, as an outlier in planetary climate data sets, Venus data calibrate and refine models of global warming upon which critical geopolitical decisions will be made for decades to come.

Understanding the cause of and cure for the so-called "ozone hole" over Antarctica arose directly from research into chlorine reactions observed in Venus' atmosphere. The worst acid rain in the solar system falls through Venus' heavy carbon dioxide air, where sulfuric acid solution replaces water as the cycling fluid. In our short film "Venus: Warnings of a Doomed Planet," scientists detail the lessons learned from comparing these macroclimates.

"We need to understand the molecular fossils that are left in Venus' atmosphere: the noble gases of argon, neon, xenon, krypton," Lori Glaze, Director of NASA's Science Mission Directorate's Planetary Science Division, says in our film. "Those gases don't react with anything else."

So, they carry a record of how fast the early Venus atmosphere escaped to space. In particular, Venus' ratio of deuterium (an isotope of hydrogen that makes "heavy water") to hydrogen today is roughly a hundred times higher than Earth's, which scientists interpret as evidence that Venus had oceans of water in the ancient past.

What washes over Venus now? Frozen waves of lava. "Most of the surface of Venus is actually covered by volcanoes," Rosaly Lopes, a planetary volcanologist at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California, says in the film. "We think that the volcanism on Venus happened fairly recently. There's like this real zoo of volcanoes."

Some, like shield volcanoes, resemble their counterparts on Earth. Others are like nothing else in the solar system: ones with flat tops that researchers call "pancake domes," some with both radial and concentric fractures resembling spiderwebs and so nicknamed "arachnoids," others called "ticks" with blobby bodies and spiky, leg-like slopes, and widespread tiny cinder cones, some no bigger than a house.

At the other end of the volcanic size range are huge caldera-like circles, with concentric cracks, called "coronae." Oddly, at the edges of the larger coronae, some sections of Venus' crust seem to be diving under others. But Venus doesn't have the kind of crustal plates geologists see on Earth. "Why do we see evidence of subduction, yet it hasn't developed into plate tectonics?" asks Suzanne Smrekar, a planetary geophysicist at JPL, in our film. "[Perhaps] the lithosphere is too hot, and that prevents the huge faults that define the edges of the plate from being maintained over a long term. Another idea is that we need surface water to help lubricate those faults and allow plates to slip past each other."

With no tectonic means to gradually vent its internal heat, Venus may undergo spasms of planet-wide eruptions. "The vast majority of Venus' surface is geologically very young," says Anthony Del Genio, Research Scientist at NASA's Goddard Institute for Space Studies in New York City. "Something happened, 500 million to a billion years ago, that created tremendous amounts of volcanism and essentially overwrote most of Venus' surface."

Left standing above the global lava fields are creased and furrowed highlands called "tesserae" that may hold confirmation of ancient oceans. "That's where we want to go," says planetary geoscientist Martha Gilmore. "These rocks are the only rocks from the first 80% of the history of Venus. Were there evidence of ancient environments that would support life? Whatever the science is to form life on Earth, everything that we know about chemistry, about physics, about geology, suggests that those conditions were there on Mars and Venus too."

Gathering evidence of past life on Venus will not be simple. Mission planners are contemplating an armada of orbiters, balloons, landers and rovers. Our short film "Venus: Doing Science in Hell" explains the engineering challenges and some promising solutions.

But the biggest challenge in finding evidence of past life on Venus may be to assemble a critical mass of public and governmental support for big Venus missions.

There's no evidence of premeditated sedition against Venus in the science or space agency communities. Yet Mars, despite its smaller mass, clearly exerts stronger gravitational influence on policy and program planning. Why?

More Mars data is available, drawing more graduate students. Thus, more careers are building around the Red Planet. It's harder to land on Mars but much easier to do surface science: Optics and electronics much prefer the cold, thin Martian atmosphere to the viscous blast furnace of Venus. If we "follow the water," we won't find any on the landscape of Venus.

We've seen a lot more of Mars' surface and it looks like Earth; so much so that lay observers easily forget its fundamental unfriendliness to biology. Visiting and populating the landscape of Mars is going to be a lot more challenging for humans than those inspirational illustrations from SpaceX, NASA and others make it look. Still, a certain Martian chauvinism persists.

In the quest for other bioworlds, Venus offers more frequent optimum launch windows and shorter trip time than Mars; much shorter than to Jupiter's moon Europa or Saturn's moons Enceladus or Titan. But can anything live on Venus? Likely not on the superhot surface! But rise up 25 to 45 miles (45 to 70 km) into the Venus clouds and you'll notice the temperature and pressure drop to that of sea level on Earth. And there's an anomaly floating in these temperate altitudes.

For more than 100 years, astronomers have photographed dark patches appearing in the ultraviolet region of the spectrum. "These patches are because something is absorbing sunlight in the clouds of Venus,' says Sanjay Limaye, a senior scientist at the Space Science and Engineering Center of the University of Wisconsin-Madison.

"Some of the properties of terrestrial bacteria mimic the spectral absorption that we see on Venus. And we hypothesize that maybe there are some microorganisms, given the fact that Venus maybe had liquid water. It had all the conditions to evolve life," Limaye added. Researchers have found bacteria in the clouds of Earth, as well as every other Earthly environment ever checked.

There's more discourse on this question, from Limaye and other scientists, in our short film "Is There Life in the Clouds of Venus?" on MagellanTV.

You can see a few clips here: "Does Life Survive in Venus' Atmosphere?"

The cloud-climate appears to shift on a scale of decades. The dark absorption patches ebb and flow. And this "living mist" concept is not new: In 1967, biologist Harold Morowitz and astronomer Carl Sagan speculated on the possibility of cloud-borne biota floating over Venus. If they are there, it should be a simple matter to find them. No landing is required, just a mission to the cool cloud tops.

"Venus winds are extremely fast," says Limaye. "On Earth it'll take you a month to fly around the Earth, whereas, on Venus, the clouds go around every four to five days and even less time than that at a higher latitude." In 1985, the Soviet Vega 2 balloon probe rode these turbulent hurricane-force thermal currents to travel more than 6,900 miles (11,100 km) at an average speed of 150 mph (240 km/h). It found the clouds at 33 miles (53 km) altitude to be warm; about 100 degrees F (38 degrees C).

Imagine what might be discovered using materials and electronics developed over the past 35 years. Geoffrey A. Landis, engineer and scientist at NASA's Glenn Research Center in Cleveland, Ohio believes we can do better than just floating at the mercy of the winds. Picture a semi-buoyant electric airplane, dispatched into the cloud layer. Sunlight, bouncing around the clouds, scatters in every direction so the plane can employ solar panels on many surfaces. In addition to analyzing the atmosphere perhaps searching for microbial life this flying platform can serve as a relay station, in contact with landers or rovers on the surface and with orbiters overhead.

"Most of the processing power, most of the computers, most of the things that run the mission would be in an airplane, that's flying 50 kilometers above, or maybe in a satellite," says Landis in our film. "And it controls the probe on the surface, almost like you'd be controlling a radio-controlled car."

Northrop Grumman Corporation's Venus Atmospheric Maneuverable Platform (VAMP) proposes a dirigible flying wing, plying the atmosphere. NASA's High Altitude Venus Operational Concept (HAVOC) envisions the beginnings of crewed sorties to the temperate zones of Venus' atmosphere.

Landis and other visionaries imagine going even further: Permanent human outposts in the clouds, depicted in our films "Venus: Death of a Planet" and "Cloud Cities of Venus"

You can see a few clips here: "Could astronauts explore Venus (and live there permanently)?"

"You could float habitats in the atmosphere of Venus," says Landis, "And the habitats could be very large. They could be kilometers in scale. You wouldn't even need hydrogen or helium. Because the atmosphere of Venus is mostly carbon dioxide, oxygen and nitrogen ordinary breathable air would float. The air that's holding you up is also the air that you can breathe. The lifting gas is your environment."

"I love the idea of a human crewed mission to a cloud city on Venus," says Jonathan Sauder, senior mechatronics engineer at JPL. "You would just need to wear some type of suit that would provide you with oxygen to breathe as well as protection from the chemical air. But you wouldn't necessarily need a pressure suit."

Sauder, however, also sees the downside: "Humans tend to not like the idea of not being able to be on firm ground. And the idea that you have to stay floating above this furnace essentially, in some ways is a hard sell!" It also requires a very powerful rocket to launch back out of the atmosphere and to pull away from Venus' Earth-level gravity for your return to our planet.

As long as we're stretching our imaginations into advanced technologies, what would it take to break the planet's global greenhouse and let the heat out? On Earth, rain pulls carbon out of the sky and into the crust, then a few active volcanoes release CO2 back into the air; a (usually) healthy balance between what scientists call "sources and sinks."

"If you wanted to scrub the Venus atmosphere, you would need an ocean, and you would need weathering," says Gilmore. "Then the carbon dioxide in the atmosphere can link with calcium and form rock. That's what sequesters our CO2. Four and a half billion years ago, Earth's atmosphere was also CO2 rich; that is the original atmosphere of the terrestrial planets."

Over the border between currently practical engineering and science fiction lies the idea that we may, someday, be able to remodel the entire second planet to be more like the third. Terraforming the transformation by technology of an object to have Earth-like climate characteristics can be an entertaining mental exercise. But is it remotely realistic for Venus?

"Well, you know, our more immediate task is to avoid "Venera-forming" Earth right now, says Grinspoon. "However, the mental exercise of imagining how we would terraform another planet is, I think, very valuable for learning how we would manage ourselves on Earth better, because it forces us to ask: How would we interact constructively with the planet?"

For Venus, constructive interaction means collapsing the heat trap, perhaps by dusting the air and getting the CO2 to condense out onto the landscape. To bind it into rock, we would need water; lots and lots of water. "If this was your goal," says Grinspoon, "there are a lot of stray icy objects in the solar system; I would take some large number of them and crash them into Venus."

In 1991, British scientist Paul Birch proposed transporting trillions of tons of hydrogen from the gas giant planets, like Jupiter, to convert atmospheric CO2 to oceans of water plus mountains of graphite. And he suggested shielding Venus from the sun's heat with enormous shade-panels; collecting solar energy while shrinking the atmosphere.

As it did with ancient peoples of Earth, Venus is still stimulating creativity! Some distant day, human ingenuity and machine intelligence may guide Venus onto a path more like the Earth. But in the nearer term, human recklessness could tip Earth's climate toward the present hellish conditions of Venus. Either way, these twin planets will grow more alike. Now, here in the Anthropocene, let's choose wisely.

Mars covered in oceans: what terraformation on the Red Planet might look like – ZME Science

Credit: Aaditya Raj Bhattarai.

Both from afar and up close, Mars looks like a desolate world that glows in bright red due to the iron-rich dust that covers the planet. However, were it to be terraformed, Mars may very well look like blue marble, similar to Earth.

In a fantastic exercise of imagination and design, a Nepal-based civil engineer mapped out Mars as it might have looked like if 71% of its surface was covered in water.

The visualizations generated by Aaditya Raj Bhattarai are part of his bachelor thesis at Tribhuwan University in Nepal, which immediately rose to fame after he shared them on the MapPorn subreddit. They show two distinct landmasses or continents, one dominated by the 20-km-tall Olympus Mons (the largest volcano in the solar system), the other more covered in flatlands, including planes like Terra Sabaea.

I am [a] big fan of Elon [Musk] and SpaceX and their plan to put man on Mars, and I hope I could help in his cause, Bhattarai told Inverse. This is a part of my side project where I calculate the volume of water required to make life on Mars sustainable and the sources required for those water volumes from comets that will come nearby Mars in [the] next 100 years.

Bhattarai notes that on his maps, the Martian sea level is as low as 963 meters below the geoid level (an approximation of the mean sea level).

Musk had previously alluded to the idea that he would terraform Mars by nuking its poles. Although it may read like satire, he was only half-joking. Later, Musk said a continuous stream of small nuclear explosions above the poles would act like artificial suns, raising the temperature.

The increasing surface temperatures would vaporize some of the carbon dioxide trapped in the south polar cap, which would end up in the atmosphere and further cause more heating. The temperature would be enough to melt the ice and provide liquid water needed to sustain life. The added liquid water would raise the atmospheric pressure to the equivalent of that found in the highest mountaintops on Earth. Although far from being survivable, it would be enough to start growing plants and trees that thrive on CO2 and produce oxygen. In March 2017, scientists grew potatoes in Mars-like soil and conditions akin to Matt Damon in The Martian, so thats doable already.

But even though these images might look enticing, Mars terraforming would be incredibly complex. It might take centuries before Mars looks anything like Earth if such a thing would even be possible in the first place.

Even so, producing an oxygen-rich atmosphere is just the tip of the iceberg. Scientists would still have to find a way to address the myriad other problems like:

Even with this out of the day, theres still the issues that:

Nevertheless, terraforming Mars might be worth pursuing. Who knows what the 22nd century might look like
