Spring reclassification: More Mars Hill teams making jump up in class - Times Daily

Over the past week, the internet has been wild over images of what appears as a doorway cut into a cliff on Mars.

But scientists behind NASA's Curiosity rover, which snapped the pictures earlier this month, said that while the strange door-like feature on Mars provides a fascinating "doorway into the ancient past," it is perfectly natural rather than the work of some aliens in hiding.

The Curiosity rover found the Mars "door" on May 7 while imaging a mound known as the East Cliffs in the Gale Crater, which the rover has been exploring since its landing in 2012. The rover used its Mastcam instrument to take the image of the strange fissure, which is only 12 inches (30 centimeters) tall and 16 inches (40 centimeters) wide, NASA said in a statement. Clearly, humans would have difficulties entering the cliff through this "door," which is why the NASA team dubbed it only the "dog door."

"These kinds of open fractures are common in bedrock, both on Earth and on Mars," NASA said in the statement.

Commenting on the internet frenzy surrounding the discovery of the "door", the Curiosity team said on Twitter that the tendency of a human brain to look for patterns that make sense in ambiguous shapes (called "pareidolia"), is behind the internet sensation.

"Sure, it may look like a tiny door, but really, it's a natural geologic feature! It may just *look* like a door because your mind is trying to make sense of the unknown," the Curiosity team said in a Twitter thread. "There are several linear fractures in the mound, but in this spot, several fractures intersect, which allows the rock to break at such sharp angles."

The team, however, added that while they don't expect a sensational discovery of an alien civilization behind the dog door, the odd crack will provide interesting opportunities for new science.

"In a less literal sense, my science team is interested in these rocks as a "door" to the ancient past," the team said.

Considering the recent renewal of interest in Unidentified Flying Objects, it is likely that not everybody will be satisfied with this explanation.

Humans have long imagined life on the Red Planet, and now, we have an idea at least of what life might sound like.

Using a SuperCam microphone on the Perseverance Rover which was developed at JPL in Pasadena NASA has been able to eavesdrop on the red planet.

But what the team has picked up isn't just for earthly fun. The measurements they've gathered provide new information about the Martian speed of sound or rather, thespeedsof sound.

On Mars, the atmosphere is different than it is on Earth it's 150 times thinner and made up of 96% carbon dioxide so sound waves also travel differently.

A quick breakdown: the experience of hearing sound is actually just the sensation of sound waves vibrating our eardrums. But to get to our ears, sound waves need something to travel through, like air..

Take a listen closely. You can pick up several different sounds a light martian wind, the crackle of a rock-zapping laser, the whir of a space helicopter, and the pings and puffs of the Perserverance gaseous dust removal tool, according to NASA's website.

Higher-pitched sounds are absorbed by the Mars atmosphere, slowing them down, while lower-pitched sounds travel long distances.

That means there are actually two speeds of sound on Mars: one for higher pitches, and one for lower pitches, according to planetary scientist Naomi Murdoch, who works on the SuperCam microphone.

"If you're listening to a concert," says Murdoch, "all of the low pitched music, all of those instruments, would arrive after the music coming from the higher-pitched instruments. So it would sound very strange and out of sync."

The Mars helicopter Ingenuity takes off on a test flight.

Murdoch notes that the sound study is particularly exciting because it's opened up an entirely new field of research. She says up until now, we haven't had microphones on other planets that have been able to capture atmospheric changes in so much detail.

And Murdoch's team isn't going to stop at Mars they hope to send microphones to other planetary bodies like Venus and Saturn's moon, Titan.

Life On Mars? Who Knows But This Is What The Planet Sounds Like - LAist

Mars is well-known for its seasonal dust storms, which can sometimes grow to encompass the entire planet. In June 2018, the dust storms became so severe that they obscured most of the planets surface, causing NASA to lose contact with Opportunity, which eventually proved fatal to the record-breaking rover. Understanding these storms and what causes them is critical to ensuring that solar-powered robotic missions continue to operate and future crewed missions can remain safe.

Specifically, scientists are looking for seasonal changes (i.e., changes in absorbed solar energy and temperature increases) that trigger dust storms and cause them to combine and grow. In a recent study conducted by researchers from the University of Houston, they could result from seasonal energy imbalances in the amount of solar energy absorbed and released by the planet. These findings could lead to a new understanding of the Red Planets climate and atmosphere.

The research was led by Ellen Creecy, a Ph.D. student with the Department of Earth and Atmospheric Sciences (EAS) at the University of Houston, as part of her doctoral thesis. She was joined by Dr. Xun Jiang and Dr. Liming Li (her thesis advisors at the EAS), as well as researchers from the NASA Goddard Space Flight Center, NASAs Jet Propulsion Laboratory, and the Universities Space Research Association (USRA) at the Lunar Planetary Institute (LPI).

The term radiant energy budget refers to the amount of solar energy a planet absorbs from the Sun and radiates outward as heat. This is a fundamental metric for characterizing a planets climate and meteorological cycles. For the sake of their study, the team combined observations from multiple missions like the Mars Global Surveyor (MGS), the Curiosity rover, and the InSight lander. This allowed them to model Mars climate and estimate the amount of energy it emitted globally as a function of season, including periods with a global dust storm.

One of the most interesting findings is that energy excessmore energy being absorbed than producedcould be one of the generating mechanisms of dust storms on Mars, said Creecy. The results revealed strong seasonal and daily variations in the amount of solar energy radiated by Mars. Specifically, they found evidence of a strong energy imbalance of ~15.3 % between Mars seasons compared to 0.4% on Earth. They further found that during the planet-encircling 2001 dust storm, the amount of power emitted globally decreased by 22% in the daytime but increased by 29% during nighttime.

As Dr. Germn Martnez, a USRA staff scientist at the Lunar and Planetary Institute (LPI) and a co-author of the paper, explained in a recent USRA press release:

Our results showing strong energy imbalances suggest that current numerical models should be revisited, as these typically assume that Mars radiant energy is balanced between Mars seasons. Furthermore, our results highlight the connection between dust storms and energy imbalances, and thus can provide new insights into the generation of dust storms on Mars.

Combined with numerical models of Mars climate, the teams results could improve our understanding of the Martian climate and atmospheric circulations. This will be especially important for future crewed missions to Mars, which NASA and China hope to mount in the coming decade. Moreover, these findings could improve our understanding of Earths climate by foretelling how our environment might behave someday. As always, learning more about other planetary environments will invariably lead to a greater understanding of our planet.

The paper that describes their findings, Mars emitted energy and seasonal energy imbalance, recently appeared in the Proceedings of the National Academy of Sciences.

Dust Storms on Mars Happen When the Planet Can't Release its Heat Fast Enough - Universe Today

ELON Musk has big plans for humans to colonize Mars and has previously said he'd like one million people to be there by 2050.

Living on the Red Planet will be difficult in itself but colonizing it could present other issues including the problem of having babies in space.

1

No one has ever gotten pregnant in space and even sex in space has never been officially recorded.

The topic is something space agencies are looking to explore as long-distance space travel draws closer to being a reality.

If humans are to one day live in space and colonize Mars, we'll need to work out how to reproduce there.

So far, several issues with sex in space have been identified.

Astronauts have previously noted that their sexual libido suffered during space missions.

The weightlessness of space is said to cause hormonal changes that could decrease a person's sex drive.

German astronaut Ulrich Walter wrote a book called 'Hllenritt durch Raum und Zeit(A hell ride through time and space)', which discusses sex in space.

The astronaut said he lost his libido during a 10-day stay in space but was reassured that it can return after a few weeks.

It's currently unclear if long space missions to Mars or living on a different planet would have a similar effect.

Without gravity, the actual act of having sex could prove to be the biggest issue.

A lack of gravity means your partner would be pushed away from you without some sort of assistance.

Former Nasa bioethicist Paul Root Wolpetold DWthat Velcro could be a solution to space sex issues.

He told the outlet: "Everything on the walls of the space station is covered in Velcro, so you could take advantage of that by velcroing one partner to the wall.

"You have to get creative in this space."

A recent study found that space radiation from a Mars mission could affect how fertile a woman is.

According to a paper in the European Journal of Obstetrics & Gynecology and Reproductive Biology: "Space travel has different effects on the reproductive capacity of women compared to men.

"The radiation exposure intrinsic to deep space travel causes destruction of some of a womansprimordial follicles.

"Data suggests that a typical Mars mission may reduce a womensovarian reserveby about 50%.

"This has consequences to a womans reproductive capacity and, more significantly, decreases the time interval to her menopause."

Mars has always been an object of fascination for many since centuries. With the advancement of technology, the scientists are now starting to discover more about the enigmatic Red Planet. Also, thanks to the various social media profiles by the space agencies, people are also getting to know intriguing details about Earths neighbouring planet. Just like this post on Grand Canyon of Mars. The post besides mesmerising people with incredible images, also teaches them more about Mars.

European Space agency posted the images on their official Instagram page. They also shared a detailed caption. Deep in the Grand Canyon of Mars. Hebes Chasma is an enclosed, almost 8000 m-deep trough in the most northern part of Valles Marineris, the 3000-km long Grand Canyon of Mars, they wrote.

The steep flanks of the trough show branched incisions and small veins of rock. Below the flanks, run-off and material from larger landslides is visible. A flat-topped mountain is located in the centre of Hebes Chasma (3). It reaches 8000 m above the graben floor and rises to almost the same height as the plain surrounding the trough. The mountain is made up of numerous rock layers stacked on top of each other, perhaps made out of remnants of an older plateau, sediments from a lake, wind-blown sediments or volcanic rocks. The rock layers were exposed by erosion, they added.

The origin of Hebes Chasma is thought to be connected to the nearby Tharsis Region, which was uplifted in the course of intense volcanism. The uplift created tremendous amounts of stress in the crust forming a series of faults oriented radially. Data acquired by the OMEGA spectrometer on-board Mars Express has revealed water-bearing minerals such as gypsum in some areas of Hebes Chasma. This is proof that at least significant quantities of water once existed in Hebes Chasma, ESA also explained.

Take a look at the incredible images that may make your jaw drop in wonder:

The video has been posted about 15 hours ago. Since being shared, it has also accumulated nearly 11,000 likes and the numbers are only increasing. The share has also prompted people to post various comments.

Wonderful, fascinating, and powerful Mars, shared an Instagram user. Amazing, expressed another. This stuns me, commented a third. Thats pretty epic, wrote a fourth.

Thats one small step for man, one giant leap for mankind, said US astronaut Neil Armstrong when he stepped onto the moon in 1969. This journey opened the door to many new possibilities for the future, including the idea of colonising space.

While it would be incredibly hard, it would not be impossible to colonise a foreign planet. This depends on the planets climate, time periods, rotational periods, and more. One of the best choices is Mars.

Mars is a terrestrial planet with a very thin atmosphere, unlike Earth, and has only one-third the gravity. However, Mars is very small compared to Earth, and its atmospheric pressure is less than ours. Thus, there is no water on the planet. Thankfully, Mars has many icebergs that can be used as water when melted, so it is not a lost cause.

In other aspects, Mars is similar to Earth, with comparable time periods for its days, seasons, and rotational periods, which make it a great candidate for colonisation. Its soil is also good for plants and has many beneficial components.

A process called terraforming would be necessary for the planet to be properly colonised. This is the process of transforming a planet, making it as similar to Earth as possible. Mars thin atmosphere makes it vulnerable to solar radiation, which would slowly strip the atmosphere and dry up the water. The terraforming process would involve replicating the Earths magnetic field and making Mars atmosphere thicker. This would stop the sun from breaking down the atmosphere.

Terraforming takes hundreds of years, and it would be ages before Mars had oxygen. The timescale for producing an oxygen-rich atmosphere on Mars is 10,000 x 17 years, or around 170,000 years, said Nasa experts Aaron Berliner and Chris McKay. However, if humanity needed space before that, biodomes made of glass would also be an option. Many plants could be grown inside to create oxygen in the dome.

It would take a lot of work to make Mars a place where humans could live. Photo: Shutterstock

Since the biodomes need light, they could be made out of high-performance glass that can keep oxygen within the dome. Because of the thin atmosphere on Mars, solar radiation would be much stronger than on Earth.

To solve this problem, the glass used to build biodomes would need to be thicker and slightly tinted. Building biodomes in the shelter of Martian caves would also be an option.

Then, buildings and houses could be constructed, eventually turning the biodome into a small city. We could build multiple connected biodomes on the surface of Mars, enough for a civilisation to develop.

A huge problem with colonising the Red Planet would be the difference in gravity. Mars has a gravity level of 0.38g, about a third of Earths, 1g. This makes moving around on the surface much easier. Nevertheless, there would still be a few problems for humans.

Their eyeballs might change shape and make work impossible; the heart might not be able to pump blood through the body and muscles might severely cramp up, said Mary Roach in her book Packing For Mars: The Curious Science of Life in the Void.

All in all, colonising space is an exciting idea that people have spent years thinking about. One day it could even become a reality, rather than the fantasy it is now.

Parents must accept their LGBT+ kids

Hilary Wong Kwok-hei, St Pauls Secondary School

Did you watch the hit show Ossans Love? If you did, did you enjoy the budding romance between the two male protagonists?

Imagine you had a child who told you they were gay how would you react? If you are fine with who they are and accept them, thats wonderful! Unfortunately, thats not the case for many parents in Hong Kong.

Nowadays, more people have come to terms with their sexuality and are comfortable identifying as queer.

But the older generation of Hong Kong, like parents and grandparents, still regards everything LGBT+ (lesbian, gay, bisexual, transgender and more) as a sin or unnatural. They grew up in a society where people used slurs to describe those in the queer community and even committed violence against them, and they have struggled to adapt to a more accepting world.

Im pretty sure Im straight - or am I?

However, their lack of acceptance has troubled LGBT+ teens. Parents are supposed to love and support their children no matter the circumstance. But many teens choose to hide who they are because they know they wont be accepted by their parents, or worse that they could be disowned. It is upsetting that many of them dont feel safe coming out and choose to stay in the closet.

Parental expectations, and the fear of rejection if they fail to live up to them, prevent queer teens from coming to terms with who they are.

Compulsive heterosexuality is one example. This is the theory that heterosexuality is assumed and enforced upon a person. Since birth, girls are taught and told repeatedly that they must only date guys and vice versa, and if they dont, they are outcasts and sinners. How will teens ever know who they are if they are not introduced to the different possibilities? Parents ignorant beliefs prevent their children from being who they truly are.

Parents should accept their kids no matter what. Photo: Shutterstock

If you are a parent, you have to understand that your childs sexuality is not a choice. Instead of shaming and shunning them, why not embrace them and help them go through this journey?

Even though they are queer, they are the same person inside and out, the same child you have raised since birth. Their sexuality shouldnt be a barrier between you two, and it may even help you grow closer as you support them through the process of discovering themselves.

And if you are a teen struggling with your identity, remember to never be ashamed of who you are. Sexuality is a spectrum, and even if you are different from others, it doesnt make you an outcast. If your loved ones cant accept you for who you are, you can try to give them time to understand. Eventually, they will come around. And if they dont, just remember that you are not alone, and there are other people that love you for who you are.

As Lady Gaga sings in Born This Way, No matter gay, straight, or bi, lesbian, transgender life, Im on the right track, baby, I was born to survive. We are all born equal, and our sexuality does not define us. We used to fight for tolerance, but now we fight for acceptance. Hopefully, there will be a future in which all parents can accept their children for who they are.

Mixed Martial Arts initially was seen as a very violent and aggressive sport. Over the years, MMA has taken a complete turn. It is now one of the fastest-growing sports in the world. The UFC has spearheaded the rise of MMA. Over the years, many actors, rappers, and celebrities have been a fan of the UFC.

While controlling the center, McGregor landed some amazing combinations on Dennis Siver. McGregor maintained range and landed spinning attacks, too. McGregor busted Siver and won round 1.

Round 2 took a similar course when McGregor while maintaining range, picked apart Siver. Minutes into round 2, McGregor landed a jab followed by a cross to the body, which knocked Siver down. The Notorious followed Siver to the ground, passed his guard and achieved mount. Once on the mount, McGregor landed immense elbows and punches, forcing the referee to stop the fight.

When UFC Superfan Bruno Mars Nailed His Conor McGregor Prediction, Yet Got the Subsequent One Very Wrong - EssentiallySports

Lets suppose you were an astronaut who just landed on the planet Mars. What would you need to survive?

For starters, heres a short list: Water, food, shelter and oxygen.

Oxygen is in the air we breathe here on Earth. Plants and some kinds of bacteria provide it for us.

But oxygen is not the only gas in the Earths atmosphere. Its not even the most abundant. In fact, only 21% of our air is made up of oxygen. Almost all the rest is nitrogen about 78%.

Now you might be wondering: If theres more nitrogen in the air, why do we breathe oxygen?

Heres how it works: Technically, when you breathe in, you take in everything thats in the atmosphere. But your body uses only the oxygen; you get rid of the rest when you exhale.

The Martian atmosphere is thin its volume is only 1% of the Earths atmosphere. To put it another way, theres 99% less air on Mars than on Earth.

Thats partly because Mars is about half the size of Earth. Its gravity isnt strong enough to keep atmospheric gases from escaping into space.

And the most abundant gas in that thin air is carbon dioxide. For people on Earth, thats a poisonous gas at high concentrations. Fortunately, it makes up far less than 1% of our atmosphere. But on Mars, carbon dioxide is 96% of the air!

Meanwhile, Mars has almost no oxygen; its only one-tenth of one percent of the air, not nearly enough for humans to survive.

If you tried to breathe on the surface of Mars without a spacesuit supplying your oxygen bad idea you would die in an instant. You would suffocate, and because of the low atmospheric pressure, your blood would boil, both at about the same time.

So far, researchers have not found any evidence of life on Mars. But the search is just beginning; our robotic probes have barely scratched the surface.

Without question, Mars is an extreme environment. And its not just the air. Very little liquid water is on the Martian surface. Temperatures are incredibly cold at night, its more than -100 degrees Fahrenheit (-73 degrees Celsius).

But plenty of organisms on Earth survive extreme environments. Life has been found in the Antarctic ice, at the bottom of the ocean and miles below the Earths surface. Many of those places have extremely hot or cold temperatures, almost no water and little to no oxygen.

And even if life no longer exists on Mars, maybe it did billions of years ago, when it had a thicker atmosphere, more oxygen, warmer temperatures and significant amounts of liquid water on the surface.

Thats one of the goals of NASAs Mars Perseverance rover mission to look for signs of ancient Martian life. Thats why Perseverance is searching within the Martian rocks for fossils of organisms that once lived most likely, primitive life, like Martian microbes.

Among the seven instruments on board the Perseverance rover is MOXIE, an incredible device that takes carbon dioxide out of the Martian atmosphere and turns it into oxygen.

If MOXIE works the way that scientists hope it will, future astronauts will not only make their own oxygen; they could use it as a component in the rocket fuel theyll need to fly back to Earth. The more oxygen people are able to make on Mars, the less theyll need to bring from Earth and the easier it becomes for visitors to go there. But even with homegrown oxygen, astronauts will still need a spacesuit.

Right now, NASA is working on the new technologies needed to send humans to Mars. That could happen in the next decade, perhaps sometime during the late 2030s. By then, youll be an adult and maybe one of the first to take a step on Mars.
