In the strange, dark world of the ocean floor, underwater fissures, called hydrothermal vents, host complex communities of life. These vents belch scorching hot fluids into extremely cold seawater, creating the chemical forces necessary for the small organisms that inhabit this extreme environment to live.

In a newly published study, biogeoscientists Jeffrey Dick and Everett Shock have determined that specific hydrothermal seafloor environments provide a unique habitat where certain organisms can thrive. In so doing, they have opened up new possibilities for life in the dark at the bottom of oceans on Earth, as well as throughout the solar system. Their results have been published in the Journal of Geophysical Research: Biogeosciences.

On land, when organisms get energy out of the food they eat, they do so through a process called cellular respiration, where there is an intake of oxygen and the release of carbon dioxide. Biologically speaking, the molecules in our food are unstable in the presence of oxygen, and it is that instability that is harnessed by our cells to grow and reproduce, a process called biosynthesis.

But for organisms living on the seafloor, the conditions for life are dramatically different.

On land, in the oxygen-rich atmosphere of Earth, it is familiar to many people that making the molecules of life requires energy, said co-author Shock of Arizona State Universitys School of Earth and Space Exploration and the School of Molecular Sciences. In stunning contrast, around hydrothermal vents on the seafloor, hot fluids mix with extremely cold seawater to produce conditions where making the molecules of life releases energy.

In deep-sea microbial ecosystems, organisms thrive near vents where hydrothermal fluid mixes with ambient seawater. Previous research led by Shock found that the biosynthesis of basic cellular building blocks, like amino acids and sugars, is particularly favorable in areas where the vents are composed of ultramafic rock (igneous and meta-igneous rocks with very low silica content), because these rocks produce the most hydrogen.

Besides basic building blocks like amino acids and sugars, cells need to form larger molecules, or polymers, also known as biomacromolecules. Proteins are the most abundant of these molecules in cells, and the polymerization reaction (where small molecules combine to produce a larger biomolecule) itself requires energy in almost all conceivable environments.

In other words, where there is life, there is water, but water needs to be driven out of the system for polymerization to become favorable, said lead author Dick, who was a postdoctoral scholar at ASU when this research began and who is currently a geochemistry researcher in the School of Geosciences and Info-Physics at Central South University in Changsha, China. So, there are two opposing energy flows: release of energy by biosynthesis of basic building blocks, and the energy required for polymerization.

What Dick and Shock wanted to know is what happens when you add them up: Do you get proteins whose overall synthesis is actually favorable in the mixing zone?

They approached this problem by using a unique combination of theory and data.

From the theoretical side, they used a thermodynamic model for the proteins, called group additivity, which accounts for the specific amino acids in protein sequences as well as the polymerization energies. For the data, they used all the protein sequences in an entire genome of a well-studied vent organism called Methanocaldococcus jannaschii.

By running the calculations, they were able to show that the overall synthesis of almost all the proteins in the genome releases energy in the mixing zone of an ultramafic-hosted vent at the temperature where this organism grows the fastest, at around 185 degrees Fahrenheit (85 Celsius). By contrast, in a different vent system that produces less hydrogen (a basalt-hosted system), the synthesis of proteins is not favorable.

This finding provides a new perspective on not only biochemistry but also ecology because it suggests that certain groups of organisms are inherently more favored in specific hydrothermal environments, Dick said. Microbial ecology studies have found that methanogens, of which Methanocaldococcus jannaschii is one representative, are more abundant in ultramafic-hosted vent systems than in basalt-hosted systems. The favorable energetics of protein synthesis in ultramafic-hosted systems are consistent with that distribution.

For next steps, Dick and Shock are looking at ways to use these energetic calculations across the tree of life, which they hope will provide a firmer link between geochemistry and genome evolution.

As we explore, were reminded time and again that we should never equate where we live as what is habitable to life, Shock said.

The holidays still happen in space, they just look a little bit different. But the sentiments are the same.

"I'm going to do whatever I can to show how thankful I am for my crewmates," said NASA astronaut Mark Vande Hei in a NASA video shared from the International Space Station Monday. "It's wonderful having all of these folks up here. We haven't been up here together that long, but wow it sure has been wonderful already."

The space station will host seven crew members throughout the holiday season.

The international crew includes Russian cosmonauts Anton Shkaplerov and Pyotr Dubrov, NASA astronauts Raja Chari, Thomas Marshburn, Kayla Barron and Vande Hei, and European Space Agency astronaut Matthias Maurer.

"We'll be working but looking forward to an awesome meal together," Barron said. "We'll invite our cosmonaut colleagues to join us, so it's a very international Thanksgiving."

The astronauts shared traditions they usually share with their families. Chari said he and his family typically go around the table and have each person say what they are thankful for, so he's going to call in "and do that remotely" this year.

The astronauts usually call home to talk with friends, family and loved ones on holidays spent far from home.

Chari also said while Thanksgiving-themed runs like Turkey Trots happen on Earth, he brought special colored headbands for him and the crew to wear as they run off their holiday meal on the space station's treadmill.

This year, the astronaut Thanksgiving menu includes crab bisque, roast turkey, potatoes au gratin, candied yams and cherry blueberry cobbler.

"I just want my family to know how much I appreciate their love and support. Even though I'm going to be really far away and moving really fast, my heart is definitely with them," Vande Hei said.

Astronauts have marked the tradition of celebrating holidays in space since the days of the Apollo mission, when the Apollo 8 crew famously shared their Christmas Eve message in a live television broadcast in 1968 by taking turns reading from the Book of Genesis in the Bible.

The first Thanksgiving in space was celebrated on November 22, 1973, when Skylab 4 astronauts Gerald P. Carr, Edward G. Gibson and William R. Pogue each ate two meals at dinnertime, although nothing special was on the menu for the occasion. The three worked on and supported a spacewalk lasting six hours and 33 minutes earlier in the day and missed lunch.

The next one didn't occur until November 28, 1985, when the seven members of the STS-61B crew of Brewster H. Shaw, Bryan D. O'Connor, Jerry L. Ross, Mary L. Cleave, Sherwood C. "Woody" Spring, Charles D. Walker, and Rodolfo Neri Vela enjoyed a special meal on the space shuttle Atlantis.

In addition to shrimp cocktail, irradiated turkey and cranberry sauce, Neri Vela famously brought tortillas to space. Unlike bread, which crumbles easily, tortillas are a perfect addition to the space menu, and they are an astronaut favorite to this day. Recently, tortillas were the perfect vehicle for space tacos made using the first chile peppers grown in space.

The first Thanksgiving on the space station took place on November 23, 2000, just three weeks after the trio of NASA astronaut William M. Shepherd and Russian cosmonauts Yuri P. Gidzenko and Sergei K. Krikalev arrived. The festive meal kicked off a celebration that has taken place on the station every November since.

The space station hosted the largest and most diverse Thanksgiving celebration yet in 2009. A six-astronaut crew, including Jeffrey N. Williams, Maksim V. Suraev, Nicole P. Stott, Roman Y. Romanenko, Frank L. DeWinne and Robert B. Thirsk, were already on board. Then, they welcomed six members of the STS-129 space shuttle crew, which brought Charles O. Hobaugh, Barry E. Wilmore, Michael J. Foreman, Robert L. Satcher, Randolph J. Bresnik and Leland D. Melvin aboard.

The 12 crew members represented the United States, Russia, Belgium and Canada, and they celebrated together two days early since the shuttle departed the space station on Thanksgiving itself.

How these holidays are marked and celebrated is up to each individual crew, and space veterans tend to share suggestions and ideas with rookies before they go up, NASA astronaut Dr. Andrew Morgan told CNN in 2020.

Morgan spent the entirety of the holiday season on the space station in 2019 alongside crewmates Jessica Meir, Christina Koch, Alexander Skvortsov, Oleg Skripochka and Luca Parmitano.

It was a busy time on the space station with multiple spacewalks and experiments on the schedule, but the astronauts were able to come together for a special meal that weekend with their international crew members and talk about what Thanksgiving meant to them.

Turkey, stuffing and mashed potatoes are on the standard menu for NASA astronauts in space, but they also saved special treats like smoked salmon and cranberry sauce to share with each other. In space, the cranberry sauce perfectly retains the shape of the can it came in. Meir and Koch also made hand turkeys for their table decor.

In 2020, the menu included cornbread dressing, smoked turkey, green beans and mashed potatoes. Japan Aerospace Exploration Agency astronaut Soichi Noguchi brought some Japanese "party food" to share, including curry rice, red bean rice and some special seafood that a Japanese high school student on Earth prepared for the crew.

For NASA astronaut Mike Hopkins, it was his second Thanksgiving in space after spending the holiday on the station in 2013.

"For me, Thanksgiving is all about family," Hopkins said. "This year, I'm spending it with my international family. We all feel very blessed to be up here and we're very grateful for everything we have."

This is how astronauts celebrate Thanksgiving in space - WAOW

For centuries, people dreamed about leaving Earth and travelling to other worlds. Then, in 1957, the Soviet Union made the first small step into space by launching a small satellite, called Sputnik. The Space Age had begun.

Early space activities were dominated by the United States and the Soviet Union. However, as time went by, Europe and Japan also learned how to build their own satellites and rockets. Today, countries such as China, India, South Korea, Israel and Brazil are developing their own space industries.

During the last 60 years, unmanned probes have been sent towards all of the planets in the Solar System, as well as many satellites, asteroids and comets. Spacecraft have soft-landed on half a dozen worlds, while rovers have driven over the surfaces of the Moon and Mars. The Sun has also been explored in great detail by a fleet of spacecraft.

Many space observatories, such as the Hubble Space Telescope, have been launched to look at the distant Universe. They have sent back some amazing pictures taken in visible light. But they can also observe stars and galaxies at wavelengths that are invisible to human eyes radio, infrared, ultraviolet, X-rays and gamma rays. The flood of discoveries has changed the way we look at the Universe.

More than 500 people have also flown in space since Yuri Gagarin paved the way in 1961. 20 people have travelled to the Moon and 12 of them have walked on the Moon. Space stations have been built, and astronauts have learned to live and work in space for many months, or even years.

ESA - Space for Kids - Space Exploration

July 20th, 2009 was the 40th anniversary of Apollo 11s historic flight to the moon, where astronauts Neil Armstrong and Buzz Aldrin became the first human beings to walk on the moon. 40 years ago, space flight inspired such awe that astronauts were hailed as heroes and celebrities by men, women, and children alike. 40 years later none of us, besides the most avid space fanatic, would likely to be able to name one astronaut in service today.

For recent Space News, check out our Space category.

Despite the tragedies of Space Shuttle Challenger, and later Columbia, where the world is shocked into being reminded of the inherit dangers of sitting on 1 million gallons of rocket fuel, or re-entering the earths atmosphere at 1,870miles per hour. We all see space flight as mundane because the vast majority of space flights since Apollo 11, have been mostly conducting seemingly routine scientific experiments. Now dont get me wrong, I believe in the importance of science in space, but these experiments dont exactly inspire awe in the general population like, oh say, a manned mission to Mars would. We also dont have the fever of beating those damned Ruskies because they might go to space and blow us all up, which we had during the height of the cold war when Apollo 11 touched down on the lunar Sea of Tranquility.

Watching some fantastic documentaries (such as Discoverys When We Left Earth) celebrating the 40th anniversary this week, I got to thinking about the importance of continuing space exploration. I hear many people decry the importance of NASA and space flight. Most saying that it is a waste of time, and more importantly money. I disagree with such assessments. I often wonder if people threw out the same criticisms of our European ancestors, who dared to explore on wooden ships to discover the new world.

In my humble opinion, space exploration is important not only to humanitys curiosity of the great beyond, but it is also important for the future of the earth and all of us living on it. So here I will count down Houston style, my top 5 reasons why space exploration is important for the world.

5. Promote Science Education The Apollo missions inspired a whole generation of kids who wanted to grow up to be astronauts, rocket scientists, and engineers. We all know that science education has been slightly lacking in the United States as of late. Dont you think that NASAs return to the moon, or more importantly the much anticipated manned mission to Mars will again inspire a whole new generation to reach for the stars so to speak? I do.

4. NASAs Environmental Research You would think that the guys who burn a million pounds of rocket fuel wouldnt be the most environmentally minded people in the world, or out of the world as it may be. However, most people dont know that NASA does a lot of good environmental research while they are up there looking down at all of us. NASA has done a lot of work in studying air quality, climate change, alternative energy, and near earth objects; which as we all know from the movies can destroy the earth any day now without warning, unless we have a group of oil drillers, a nuke, and Bruce Willis.

3. Eliminate Earth Over Population The current earth population is almost 6.8 BILLION people. Arguably beyond the carrying capacity of the earth already. The big dream is space colonization. We need somewhere to put all these people, or we all might end up living in skyscrapers, see all animals habitats destroyed, and smog up the air beyond what is breathable (see: China).

2. Natural Resources Related to over population, we are burning through the earths natural resources pretty quickly. Out in space there is virtually unlimited resources. It is all just a matter of collecting it and bringing it back, which granted will not be an easy task. Still it is virtually unlimited natural resources! There will be no more excuses for hiking up prices on barrels of oil. (Although hopefully we will have moved far beyond oil by then).

1. Put Ourselves into Perspective From space earth is really small. From space earth is really fragile. Sometimes I think it would be a good thing to put our place in the universe into perspective. I dont go into your house light up a stogy, start pulling up your carpet, kick down your door, and then kill your cat. Yet, we as the human species have been doing that to our own home the earth for quite a while now. If we start seeing how small and fragile we are out there floating in space, maybe, just maybe we will not be so prone to abusing our one true home.

Blast Off! Heres to the men and women who gave their lives to explore the great unknown. We cannot ignore the importance of space exploration, nor be complacent in its meaning to all of us. I hope space exploration can continue to inspire, educate, and provide for us in the next 40 years as it has the last 40 years.

Top 5 Reasons why Space Exploration is Important for the ...

NASA and the Department of Energy (DOE) are asking U.S. companies for help putting a nuclear reactor on the moon by 2031.

Providing a reliable, high-power system on the moon is a vital next step in human space exploration, and achieving it is within our grasp, Sebastian Corbisiero, the Fission Surface Power Project lead at the DOEs Idaho National Laboratory, said in a news release.

The challenge: NASA plans to send astronauts back to the moon as soon as 2025, with the goal of establishing a long-term presence on its surface. While there, astronauts will conduct research that will help NASA figure out how to send humans to Mars for the first time, perhaps by learning how to extract rocket fuel from moon ice.

They wont be able to conduct that research, though, if they dont have plenty of power for their rovers, life-support systems, and other tech.

NASA wants reactors that can produce 40 kilowatts thats enough to sustain 30 households for 10 years.

Plentiful energy will be key to future space exploration, Jim Reuter, associate administrator for NASAs Space Technology Mission Directorate, said in a news release.

Some of this power can come from solar panels, but lunar nights can last for weeks, and NASA also wants to be able to explore places sunlight cant reach, such as deep within the moons lava tubes.

The idea: NASA believes nuclear could be the ideal energy source for lunar astronauts since its reliable and powerful. It actually might not be too difficult to put a nuclear reactor on the moon, either.

While the nuclear reactors providing power here on Earth tend to be massive, researchers are already developing microreactors small enough to transport by truck and the less weight NASA has to send up, the cheaper the mission will be.

A reliable, high-power system on the moon is a vital next step in human space exploration.

The ask: NASA and the DOE are now asking U.S. companies to help them put a nuclear reactor on the moon for a demonstration within the next 10 years.

Specifically, they want proposals for nuclear systems capable of producing 40 kilowatts about how much 30 households use over the course of a decade while operating autonomously from the deck of a lunar lander or rover.

Proposed reactors must also weigh less than 13,200 pounds (about 6,000 kg) and be able to fit in a cylindrical container 18 feet long and 12 feet wide.

Putting a nuclear reactor on the moon could drive innovation for fission on Earth.

Looking ahead: Proposals must be submitted by February 9, 2022. NASA and the DOE will then spend a year helping chosen companies further develop their nuclear reactor designs.

Using what they learn from that process, NASA and the DOE will then ask companies for final design ideas. One of those systems will then be built and sent to the moon within the next decade, if all goes according to plan.

The big picture: Putting a nuclear reactor on the moon would not only help with space exploration, it could also drive innovation for uses here on Earth, according to NASAs Reuter and that could be huge in the fight against climate change.

Nuclear is the most reliable source of clean energy we currently have available, but many existing plants are nearing the end of their lifespans, and building similarly sized replacements can take billions of dollars and most of a decade.

Smaller nuclear reactors could be put into use far more quickly and for far less money, if we can work out the kinks in developing them and NASAs plan to put a nuclear reactor on the moon could help us get there.

NASA plans to put a nuclear reactor on the moon by 2031 - Freethink

ALBUQUERQUE, N.M.(KRQE) New Mexico Institute of Mining and Technology (NMT) is one step closer to space exploration thanks to the Air Force Research Laboratory. The university is getting $6.2 million to complete the first phase of its $30 million five-year project for the Magdalena Ridge Observatory Interferometer.

When complete, the project will improve detection and characterization of objects at Geosynchronous Earth Orbit and beyond, said Van Romero in a news release, vice president for research and professor of physics at NMT. It will allow astronomers to assess the health and orientation of man-made objects and study starspots, newly forming planets around young stars, and accretion disk physics around super-massive black holes.

With the money, New Mexico Tech says it will be able to build three telescopes and two scientific instruments in Socorro. The funding will also support a team of more than 40 scientists, engineers, students and support staff.

According to the news release from the Air Force Research Lab, the Magdalena Ridge Observatory Interferometer will be one of the largest Earth-based optical telescopes, made up of collecting mirrors that work together to produce images with resolutions equal to a single telescope of more than three football fields across.The news release states that the observatory is expected to be completed in 2026.

The news release states that NMT anticipates the facility will be available to public tours, and K-12 school programs, and will promote collaborations with universities.

Air Force Research Lab, New Mexico Tech to further space exploration - KRQE News 13

Space is thought to be unlimited, but the lower Earth orbit (LEO) is limited - and filling quickly up with new satellites and space litter from old ones.

The lack of space has already put the two richest men on planet Earth, Elon Musk and Jeff Bezos, at odds.

Musk's Starlink has placed some 16,000 satellites in orbit to deliver high-speed internet to anyone on the planet.

Amazon's Bezos' competing project, Kuiper, hopes to have 3,200 satellites in operation after its first launch in 2022, while OneWeb is more than halfway to its target of 648 satellites.

A request from Musk, to move some of his Starlink satellites to a lower altitude than originally planned, recently led to a dispute at the American Federal Communications Commission (FCC).

This is perhaps the first, but certainly not the last, dispute over how to operate in space.

The American Federal Communications Commission earlier this month (3 November) granted aerospace giant Boeing permission to place 147 satellites in orbit, while French satellite company Kinis was granted permission (18 November) to offer satellite services in the US market from 25 small, low-Earth orbit satellites.

There are two main reasons why the world is facing an exponential growth of satellites. First, it has never been easier to get a satellite into space and secondly, satellites have become smaller.

The global space economy represents more than 300bn per year, and could double within a decade, according to a report from the European Space Agency high-level advisory group on accelerating the use of space in Europe, published in October.

This commercial explosion touches on all sectors of space, from launchers to applications, from exploration to the LEO economy, it said. What will be Europe's share of it?

"Today, we have three nations [the US, China and Russia] being capable of launching their own astronauts into space, with one coming up very soon, India; and there will be others on the horizon," European Space Agency (ESA) director, Josef Aschbacher told a press conference in Portugal on Friday (19 November).

"The question is - does Europe also want to have its independent access to space for future space exploration? This means the next frontiers, which are of course in low-Earth orbit, but also on the Moon, on Mars and beyond," he said, at the end of a meeting of ESA member states ministers in the Portuguese city of Matosinhos.

The ministers adopted a new vision for space activity in Europe, the Matosinhos Manifesto.

A European space summit will be held in February 2022 in Toulouse, coinciding with France holding the Council of the European Union presidency from 1 January to 30 June 2022.

The summit is set to boost Europe's ambition in space for the next decade by announcing new flagship space programmes in addition to Copernicus and Galileo.

However, one big hurdle will be to find the public budgets needed to make such visions into reality.

"Human space exploration is well understood. The question is if Europe wants to develop its own capabilities in the medium to long term. I would like to ask the question to decision-makers. Is this something where Europe should really engage itself?" ESA director, Aschbacher said.

It is one thing is to send communication, navigation and observation satellites into orbit. It is another thing is to send astronauts, as European and Americans call humans in space. Russians who travel into space are known as cosmonauts - while China calls them taikonauts.

Musk's SpaceX in September 2021 sent the first four civilians 580km above the surface of Earth, which is even further away than the International Space Station.

ESA has currently seven active astronauts working closely with the American NASA astronauts, as Europe is not capable of launching their own astronauts into space. ESA is, however, recruiting a new crew of astronauts for future missions.

"Space is becoming a much more important sphere not just for humans but in all aspects of our lives; we see that through communication satellites, navigation satellites, earth observation satellites that really have become part of our infrastructure now. They are integrated into our modern societies," ESA astronaut, Andreas Mogensen, told EUobserver.

Mogensen and his NASA colleague, astronaut Kathleen Rubins last week (19 November) finished joint geology field trips to the Italian Dolomites and the Ries crater in Germany, as well Lanzarote, a Spanish volcanic island, in preparation for a potential landing on the Moon.

"Walking in a volcanic environment on the Earth, on the Moon surface or on Mars is actually very similar", Rubins explained to press on Lanzarote.

Time on the moon will be limited, as well as capacity, and astronauts need to know enough geology to understand what samples to pick, describe, measure and bring home.

"This is a very exciting time because it has been decided now to take the next step. We had more than 20 years of experience onboard the international space station where we learned what it means to live in space for longer periods of time. Six months even a year. And now we are going to return to the Moon hopefully this time to stay to create a presence on the Moon, a space station and then the plan is if everything goes well to take that experience and then in 10, 20, 30 years send humans to Mars," Mogensen said.

"The NASA plan is that when we return to the moon it is going to be with the first woman and the first person of colour onboard. This is not only an American plan it is actually an international plan", Rubins said.

She stands a very good chance to become the first female to set foot on the moon herself.

"It has been interesting to see a lot of the commercial space explosion happening. We want to go further and we want to explore, but really to do that we need to enable a commercial market. My hope that this allows us to expand space exploration and that we make this is not just for a few single individuals but that more people can get involved", Rubins said.

"As costs get lower and lower the access becomes available to more countries that want to send experiments to space, educational opportunities make space available to everybody. So, I see this as definitively 'collaboration'. It helps our space programme", she said.

The European Space Agency's headquarter is located in Paris, France. But it is not an EU institution, just working closely with the European Commission and members states and receiving some 25 percent of annual budgets from EU coffers.

There are around 2,200 staff working for ESA and the budget for 2021 is 6.49bn, which is only around a quarter of US public spending on space activities.

EU budgets are also directed at a new EU body called the EU Agency for the Space Programme (EUSPA) which was officially launched on 12 May 2021. It is based in Prague and oversights everything the European Union does as a bloc in orbit.

ESA and EUSPA are separate entities with national memberships that do not completely overlap - for example, the UK is in ESA but not in the EU, and therefore not in EUSPA.

A Financial Framework Partnership Agreement (FFPA) defines responsibilities and details the amount of money contributed by the EU to ESA up to 2027 - some 9bn out of a total EU space budget of 14.88bn.

European states also invest in their own national space programmes and activities.

France committed for example in October 2021 1.5bn to space as part of the "France 2030" investment plan, Norway announced it has secured funding to build a spaceport on the island of Andya, and Sweden for a spaceport in the Esrange Space Centre in Kiruna.

Scotland's government recently launched a new Scottish Space Strategy and even little Monaco established an Office for Outer Space Affairs.

During this weeks Space Caf, SpaceWatch.Global publisher Torsten Kriening caught up with the Director of European Space Resources Innovation Centre (ESRIC) and Director for International Affairs & SpaceResources.lu at the Luxembourg Space Agency (LSA) Dr. Mathias Link.

Mathias is recognised as an expert in the field of space resources and currently works on the definition and implementation of Luxembourgs space sector policy, with a focus on international affairs, legal & regulatory issues, research, as well as finance. For more than ten years, Mathias Link has represented Luxembourg in space-related boards at the European Union and ESA, as well as in the United Nations Committee on the Peaceful Uses of Outer Space.

This week, he and Torsten talk about why space resources will be driving the future of space exploration, Luxembourgs interest in space resources, and the community and start-up programme ESRIC and the LSA offers.

Luxembourg and interest in space resources

Luxembourg has been active in space since the 1980s, starting in commercial satellite communications with the creation of SES. Since then, the sector has grown, becoming an integral sector in the countrys economy.

And the sector is also recognized as one of the key priorities for diversification of our economy.

Mathias explained that from the government side, they began looking at space resources about 10 years ago.

We started looking into this and saw that this was actually very promising, obviously, space resource utilization, meaning using different resources like water gases, metals bring a lot of different applications.

The huge potential of space resources was recognized, and so Luxembourg began to investigate this.

And that led them to the launch of the space resources to the EU initiative in February 2016, where we gave ourselves the objective to contribute to the peaceful exploration and sustainable utilization of space resources for the benefit of humankind. And since then, we have really implemented a lot of different activities on many different aspects and layers.

This means, many different international partnerships with European partners at the European Space Agency, and the European Union, as well as becoming active at the United Nations. And adopting a national law in 2017, recognizing the possibility of resources ownership, but also laying down a complete framework for the authorization and supervision of corresponding missions.

Challenges putting the ideas into action

Mathias states that there are a few different challenges when putting space resources on the map in Luxembourg for both the public and the private sector. These challenges are on a technical, regulatory, and financial level.

And of course, you have the overall challenge that all these individual challenges are very much interlinked, they are very much related, you will of course, not find an investor investing in markets that do not exist with unclear legal issues and with an immature technology.

Another big challenge takes shape in trying to develop sustainable activities in cooperation with the private sector.

And the difficulty here is, of course, that we very often try to address markets that do not yet exist.

In order to address these challenges, there has to be a parallel focus and the role of governments and agencies is that of a bridging entity playing the role of an anchor for customers or early risk-takers to support the private industry.

And more specifically, what we have tried in Luxembourg is to look for companies that share this long-term vision that we also have, but also have ideas on proposing near term business models addressing existing markets in space and on Earth.

The Goal of ESRIC

ESRIC is an initiative that we took together with ESA, responding to both Luxembourgs national strategy space resources towards the EU, and to the ESA strategy on space resources, which was published in May 2019.

What we aim with as ESRIC is to create a new internationally recognized centre of expertise for both scientific and technical aspects, but also business and economic aspects related to the use of space resources. And of course, we do this again to go further in human and robotic exploration, but also to lay the grounds for future in space economy.

Mathias explains they are active in four main pillars on the global level.

The most important one, I would say, is the research pillar, where we will start research activities all along the value chain of space resources. So really going from the prospection of resources to the mining and beneficiation of these resources, and then to the processing and, and manufacturing of these resources into viable applications.

The second pillar is business with a focus on pushing commercial partnership but also including the launch of a launched support program for start-ups.

The third pillar is a platform to bring together the community in Europe.

Europe, because we know that many players that are active in this field, but what is missing is more opportunities to bring them together to exchange ideas and to come up with new projects.

The fourth pillar is the knowledge management pillar, where they try to build up a central platform together to structure and to make the knowledge available that exists in ESRIC, but also in Europe and even on an international level.

Bringing in the non-space industry

Now specifically for space resources, what we are doing is trying to increase the level of recognition and taking it seriously because I agree with you when you hear this for the first time, it sounds a bit like science fiction, but that has to change

In order to do so, Mathias describes that its all about taking the time to explain. They are active in the media showing the opportunities that are linked to space resource utilization to the general public.

So thats one thing, trying to just generally increase the knowledge. And by that also bringing in people and companies maybe that, that did not think about this as a huge opportunity.

ESRIC does not want to solely focus on research, but rather aid the develop further companies in this field. To do so, they launched the ESRIC start-up program at the ISC a few weeks ago.

The aim of that program, which is actually the worlds first fully dedicated to space resources, companies are to work in three phases.

The first phase, which companies and groups from all over the world can join, is about mentoring, bringing in teams that will receive both business and technical advice from the partners of ESRIC. The second phase is the incubation phase in Luxembourg, with office spaces and,000 euros of an initial grant to help develop the team. The third phase is residency, where the start-ups that are actually very close to the researchers and also have the opportunity to stay at ESRIC for a longer time.

Finally, the age-old question

What will come first: Asteroid resources, or Lunar resources?

To this chicken and egg question, Mathias explained, that they have conducted some studies and the results were very clear.

I think the moon has a lot of advantages in being more accessible, also having a lot of interest in recent years. So, the first space resource utilization, or lets say larger utilization will be on the moon.

From there, the further activities can happen in low Earth orbit, or Earths orbit in general, and then serve as a stepping stone towards Mars. Mathias states that asteroids also have a lot of advantages, which will be the next step to address.

As Thanksgiving approaches, many people will have the opportunity to relax, unwind, and log the kind of gaming hours only possible during an extended holiday weekend. Halo Infinites multiplayer will likely be a highly popular choice, almost guaranteeing servers will be crammed with players the way Los Angeles 405 freeway is crammed with travelers every Thanksgiving season. So, in the event you just cant connect to a game of capture the flag, or if you have no interest in the multiplayer at all, here are the best non-Halo Infinite games were playing to make it through the holiday.

Andrew Final Fantasy VII: The First Soldier

It turns out the thing that finally pulled me away from Fortnite was a game thats a lot like it, only set in the world of Final Fantasy VII. The First Soldier is the most unexpected of prequels. Its set a few decades before the events of FF7, exploring the SOLDIER program thats so integral to the storyline. But instead of a single-player adventure like you might expect, its a battle royale crossed with an RPG. Think of it like Fortnite without the building, set in Midgar, and with magic spells to wield and monsters to battle. You get the same last player standing thrilled, but with deeper character progression and familiar locations to battle it out in. The gunplay is a little floaty, and the map could use some more points of interest, but theres something really fun about perching on top of Seventh Heaven with a sniper rifle. Just be sure to avoid those Tonberries.

Sean Genshin Impact

Almost every evening, my five- and two-year-old daughters ask me for Adventure Game by which they mean firing up Genshin Impact so they can watch an array of sword and magic-wielding waifus explore a radiant Breath of the Wild-style landscape. Im going to admit I initially sat on this game, turned off by the pay-to-avoid-grinding mechanics and the idea it was a Zelda clone. But so far, its surprisingly deep. The initial European castle / church vibe, with fights against goblins and automatons, soon gives way to an idyllic ancient Chinese landscape, including a gorgeous harbor town filled with agents of intrigue. (Apparently, many spots are inspired by real-world Chinese locations.) My daughters only get to watch a little bit before bedtime, though, so thats as far as weve gone. This holiday, Im going to try to get us to Genshin Impacts growing Inazuma region so we can visit Japan as well. BTW, its a great showcase game for new hardware: it runs amazingly on PS5 and surprisingly well on the latest iPhones.

Makena Stardew Valley

Over the next few weeks, Ill be spending hours on a train, in a car, and in the air trying to visit me and my partners families before the holiday season is over. Ive never been a big gamer when traveling its hard to focus on a game when Im constantly worried about losing my tickets or missing my boarding time. But Stardews simple gameplay lets me drop in and out of fishing or tending to my cows in between the stressful moments in the airport or train station. My partner and I share a farm in the game, and were able to chat about our plans for the upcoming season or designate chores. The games collaborative nature gives me an opportunity to connect with my partner while traveling rather than stuffing my nose in a book while he sleeps. Its a pleasant and less stressful way to pass time!

Adi Deaths Door

I cant personally vouch for Deaths Door yet because Ive been waiting to play it on Nintendo Switch, and it finally came out on Tuesday: a land of pure, untapped potentiality. Its an action-exploration game about a crow who collects peoples souls, which sounds cool? I hear its a little like Hollow Knight, a game Id played for about 70 hours last I checked? Ive been reading great things about it on PC for months? Either way, Ive got my Polygon beginners guide up and the start screen ready.

Alice Forza Horizon 5, Age of Empires 4

Few open-world games have dug their claws into me quite like the latest installment of Forza Horizon. Most open-world titles cause my eyes to glaze over once I see how big the map actually is, filled with tons of tiny markers that Ill never pick up and activities Ill never complete. However, cruising around Mexico in everything from modern supercars to an antique Volkswagen is strangely meditative, even with the throttle pinned at 180MPH. I know the map is absolutely littered with stuff to do, but Forza doesnt have the same FOMO as its contemporaries. There is a level of appreciation for the extensive library of cars that I will never truly understand, but there will always be a strange, primeval part of me that loves something that goes VROOM, even as someone who has never owned a car.

And for something entirely different, Ill likely also be spending a decent amount of hours with Age of Empires 4. I managed to bulldoze my way through the single-player campaigns (on easy), but Ive been working through the various masteries of the different civs (Franks FTW) and working up the nerve to fight the intermediate AI. I know Im not the only one with a special place in my heart for the Age of Empires franchise, but its been too long since weve had an honest real-time strategy to celebrate. Indeed, I fully intend to spend some quality time with AOE4.

Cameron Inscryption, RE4 VR, Shin Megami Tensei V

Ash asked us to not say Halo Infinite, which is good because thats what I was going to say (my friends and I play it, and its just good fun; sorry, Ash). Currently, Im hopping between Inscryption, the VR port of Resident Evil 4 for Quest 2, and Shin Megami Tensei V. To be perfectly honest, I was content with the idea of skipping Inscryption, but the industrys collective praise of it was coercive (and loud) enough to push me to buy it. Im not much of a card game person, but theres definitely enough intrigue and unique elements at play to keep me going. So, here I am, encouraging you to give it a try, too, if you have a PC.

Atlus Shin Megami Tensei V for the Switch was another game I was able to resist at first. I was reluctant to jump in willingly because earlier in 2021, I finally played through Persona 5 to the end. That was fun but also kind of exhausting. While SMT V is a very different beast, I knew the battles would feel similar, to the point that I had to stop and think if I really wanted to embark on whats likely to be an 80+ hour experience. Anyway, I bought it, so Ill let you know how it is in a year when I finish it.

RE4 for the Quest 2 is incredible. Armature Studio, the team that developed the VR port, touched the right amount of things to make the game feel fresh, yet in most ways, just as I remembered playing it on Gamecube. Im trying to force myself to take my time. Its too special to gobble up like a Turkey Day meal.

Gloria Animal Crossing: New Horizons 2.0 Update, Just Dance 2022

Ill confess: its been months since I last hung out with my villagers on my Animal Crossing island, and even then, I was playing in time travel mode to check out the special events Id missed (like Mario Day). Knowing how extensive the November 2021 update is, Ive been avoiding my Switch until I have time to go all in. With Black Friday and Buying Guides now out of the way, I cant wait to escape to my virtual island.

Im looking forward to sipping a latte at Brewsters, getting Kappn to serenade me on the way to exotic islands, buying a sick gaming setup for my house, and even growing veggies and learning to cook in the game. So far, Ive only managed to buy one pack of the Animal Crossing Series 5 Amiibo cards, so Ill try to bring those new villagers to my island (even though I dont like my cards). I hope I can get into ACNH 2.0 without needing to weed too much first. I cant even wrap my mind around the Happy Home Paradise expansion pack yet maybe remind me in December.

The other game Im excited to try is Just Dance 2022 for the Xbox Kinect (yes, I bought a used Kinect just for this series). Ill need to work off my Thanksgiving dinner somehow!

Antonio Metroid Dread, Dark Souls Remastered

I have barely touched Metroid Dread and my SWOLED since I got them, so Im hoping if I have any time during the holiday to play games not named Halo Infinite when Im not with family or working on our Black Friday deals coverage Ill finally make some solid progress. I loved Metroid Dread from the first moment, though I had a false start early on when I got lost and thought I might have missed something important. A fresh restart from the beginning has solved that, so now I just need to play frequently enough that I dont forget everything again. Games really could use a you havent played in two weeks, heres what you were up to type of recap.

I also just got Dark Souls Remastered on PC as a birthday gift, so I guess Im looking forward to feeling some pain during the holiday that isnt related to food comas and overeating.

Mitchell Kentucky Route Zero

Ive slowly been working my way through a Kentucky Route Zero replay (which I plan on finishing during a few flights), and its episodic nature feels perfect for those holiday nights where youre looking to wind down after everyones turned in for the night. KRZ is almost all vibes with little gameplay, but Ive loved re-experiencing the twists and turns of its Americana-fueled story, which is as weird and mythic as it is deeply sad. It may not be the game to play right before a cheerful Thanksgiving dinner, but if youre looking for something to turn over and over in your mind (or just dont want to wait until Stray comes out next year to play as a cat) over the holidays, Kentucky Route Zero is well worth your time.

Ash Exo One, Ace Attorney Chronicles 2

I am both in love with and terrified by space. Exo One marries the wonder of a simple exploration game with the sheer, unfathomable terror of space, and its therefore extremely my shit. You pilot a weird, orb-like spacecraft through empty but painfully beautiful alien worlds, picking up power-ups that make it roll faster and glide longer as you learn the story of a doomed expedition to Jupiter. Visually, Exo One is stunning. I am in awe of my surroundings as I bounce off sand dunes and skip over rolling waves, trying to hit the right piece of land in just the right way thatll make my craft zoom into the cloud-strewn atmosphere. Its wonderful. Exo One feels like the best bits of Interstellar and Sunshine pure space exploration without all the messy human stuff.

During my holiday break, Im taking care of a family member recovering from major surgery. Ace Attorney Chronicles 2 is my goodnight game. Since Im away from home, Ive had trouble sleeping, especially after a long day of keeping track of medicine, appointments, and meal plans. To unwind, Ive been slowly making my way through Ace Attorney Chronicles 2 letting my mind drift off (making my thumb accidentally hit the skip dialogue button) as I work to defend the innocent and solve murders most foul. I adore the new characters and the slow, methodical untangling of plot points introduced an entire game previous. Even if some of the puzzles require fantastical stretches of logic, Ace Attorney Chronicles 2 is the perfect nighttime calming agent to a stressed-out brain.

Barbara Doctor Who: The Lonely Assassins

I havent been much of a gamer lately except for a few ongoing Scrabble games that Ive been playing with friends for about three years now. However, I just got myself a brand new Pixel 6, and so Im going to be investigating a bunch of Android games on that slightly-too-big screen. While several of the games mentioned here are on my list including Genshin Impact and Stardew Valley Im going to start with Doctor Who: The Lonely Assassins. What can I say? Ive been a Doctor Who fan for many years, and an adventure game that allows me to interact and solve puzzles with a Timelord is the perfect way for me to get back into gameplay.

Richard Apex Legends, Forza Horizon 5

Sure, I might turn the clock back and get into some Big Team Battle this weekend. But mostly, Ill stick to the game that the Xbox Museum says is my most played for 2019, 2020, and 2021, with a strong chance of repeating for 2022. The new map in Apex Legends did its job for me by changing the gameplay just enough to keep things fresh without breaking what it does well. Opening up large spaces for action but separating most of them with high walls has lowered (but not eliminated) the endless chain of third parties that you get on the games other maps as long as you know how to navigate the area without jumping into the abyss.

When I need to switch things up, Im plugging in my wheel and taking on Forza Horizon 5. No, they havent addressed the Horizon series flaw of having way too many options for what you can do next... or the rubberband AI. Simply existing as the first Forza game with good lighting is what Ive been waiting for in this series.

Victoria Pokmon Snap, Pokmon Shining Pearl

In real life, my camera roll is just thousands of photos of my cat and dog so Pokmon Snap makes perfect sense. Its so soothing. Theres no battles. Its just dozens of cute pokmon going about their business in scenic locales, and its my job to be their paparazzo. An Alolan Raichu surfing the sand dunes? Yes, please. A derpy Mantine leaping out of the sea? Hell yeah. Plenty of Bidoof butts to go around.

When I need a break from Professor Mirrors arbitrary photo grading the man has no appreciation for the rule of thirds Im living my best life running around the Sinnoh region with my Piplup. Im not big into the endless gym battle grind, so the contests (aka pokmon beauty pageants) are a nice change of pace. You really cant find a better distraction from family drama than hundreds of cute pokmon.

The best games to play this Thanksgiving weekend - The Verge

As per NASA, both the orbital debris and spacecraft travel at speeds of about 15,700 mph in low Earth orbit. (Modeling image: IRAS/TU Braunschweig via ESA)

Space Junk: If you are at all interested in the activities happening outside the Earth, you would have heard that recently, that a defunct Chinese satellite nearly collided with the International Space Station, and it was only averted when the ISS manoeuvred out of the way. While the event was enough to bring up the debate of space junk all over again, what has added to it is the fact that a new study has found that very soon, the Earth could also have Saturn-like rings but of space junk! And if that is not troublesome, I dont know what is.

Heres some context for you. According to US space agency NASA, the US Department of Defenses global Space Surveillance Network (SSN) sensors are tracking over 27,000 pieces of space junk, or as they are technically called orbital debris. Now I know what you are thinking 27,000 pieces in the vast space? Thats not so bad. But it is, because these are pieces in the near-Earth space environment. And there are many more pieces that are present close to Earth but are not large enough to be tracked. They are, however, large enough to cause trouble for human spaceflight and robotic missions.

Also read | Is it Earth or is it Saturn? Soon, space junk will form rings around our planet and its very troubling

As per NASA, both the orbital debris and spacecraft travel at speeds of about 15,700 mph in low Earth orbit, and therefore, even a tiny piece of space junk can cause major damage if it were to collide with a spacecraft. The rising population of space debris increases the potential danger to all space vehicles, including to the International Space Station and other spacecraft with humans aboard, such as SpaceXs Crew Dragon, NASA says.

Orbital debris is any human-made object in orbit about the Earth that no longer serves a useful function. Such debris includes nonfunctional spacecraft, abandoned launch vehicle stages, mission-related debris, and fragmentation debris, NASA explains.

With space junk travelling at very high speeds, not only do ISS and rockets need swift manoeuvres, but scientists would have to ensure that new satellites have a swift automated response to detect and prevent collision with the orbital debris, or investments worth millions of dollars would vanish into thin air, quite literally.

The concerns around space junk have been increasing ever since an inactive Russian satellite collided with an active US one back in 2009 while they were travelling at speeds of about 22,300 mph and turned into thousands of pieces of tiny debris.

Space junk not only pollutes space (which should, frankly, be left free from the ill-effects of human life), but it also causes a vicious cycle to emerge. Orbital debris can collide with other human made objects and in turn create more pieces of debris which would each prove to be hazardous while whizzing about in space. Not only that, but if the debris is also likely to collide with other celestial objects that might cross the orbit of the Earth and cause some damage to them.

However, recognising this problem, more and more space agencies and organisations are trying to come up with a solution.

Japan had a few years ago sent an experimental space junk collector that would grab onto pieces of space junk and bring them to the Earths atmosphere to be incinerated. This experiment, however, had failed when the spacecrafts tether failed to be deployed.

Not being discouraged by this, however, Japans Astroscale earlier this year launched a demonstration satellite that would locate and retrieve used satellites and other pieces of space junk. Apart from this, the European Space Agency has also finalised a contract for a 2025 mission to capture and dispose of a piece of space junk with the help of a four-armed claw.

One thing that is bothering, though, is that while some private companies are concerned about space and cosmic pollution, the focus of NASA with regard to space junk ends at its impact on satellites and spacecraft. Though that is a fair concern and an important issue considering the increasing space exploration missions that are being carried out, it is not the only one, nor should it be the main one.

The main issue is that just like the Earth, too much junk or debris can cause a cosmic imbalance at least around the Earth, Moon and Mars, where most of the exploration missions are headed at the moment. It is estimated that an average of 400 pieces of space junk (very small pieces) fall on Earth every year, but now, larger pieces of debris are also floating about. Such pieces of junk, while relatively harmless now, can create major problems in how the solar system functions if they accumulate in large numbers. Right now, air pollution on Earth blocks our view of the sky, but exaggerated as this may seem, who knows one day we might just see a whole lot of space junk in the sky! It could also alter the balance between Earth and space due to such close proximity to our planet, and such an imbalance might lead to the end of all life on the planet. We already know that conditions required for sustaining life are rare and any change can cause the scale to tip. We really need to ask ourselves is space junk really the hill we want to die on?
