Billionaire Elon Musk has long been vocal about his ambitions for colonizing Mars here's everything we know about his plan.

Musk founded SpaceX in 2002 and since then has constantly reiterated one of his biggest goals is to help make humankind a multi-planetary species.

In order to achieve this otherworldly feat, the world's richest man (at the time of publishing) turned his attention to the red planet, located approximately 33.9 million miles away from Earth.

"If we are able to make life self-sustaining on Mars, we will have passed one of the greatest filters. That then sets us up to become interstellar, Musk wrote on Twitter in November.

Earth is ~4.5B years old, but life is still not multi-planetary and it is extremely uncertain how much time is left to become so, he added.

So far, Musk's long-term vision for Mars looks something like building a self-sustaining city that features solar-powered hydroponic farms and vegan diets.

The next really big thing is to build a self-sustaining city on Mars and bring the animals and creatures of Earth there, Musk told Time.

Sort of like a futuristic Noahs ark. Well bring more than two, though its a little weird if theres only two, he continued.

In Elon's scenario, humans and animals would live permanently in this Mars city albeit in "glass domes" until the process of terraforming happens.

'Terraforming' is the hypothetical process of modifying a martian surface to make it habitable by Earth-like life.

In this case, terraforming would eventually allow humans to breathe on the red planet without oxygen masks or glass domes.

Still, even Musk added that terraforming would be "too slow to be relevant in our lifetime," however, humans could certainly establish a human base on Mars in this lifetime.

So what does this human base look like, and how do we build it?

It starts with building a large fleet of SpaceX Starships that could carry the required amount of equipment and supplies required to get a settlement going, per The Space Review.

Theoretically, if one Starship stage can carry 200 tons of cargo to the surface of Mars, then 5,000 trips would be able to carry one million tons.

Once the equipment has successfully been transported to Mars, the next concern is food production.

According to The Space Review, around 200 square meters of growing area with 100 kilowatts of power would be needed per person, which equates to a construction crew of 100 people with 10 megawatts of power and 20,000 square meters of growing area for food production.

In theory, a one-square-kilometer farm transferred to Mars (250 by 250 meters with four growing levels), could potentially feed 5,000 vegetarians.

Geologists could also potentially discover mineral site deposits, which would greatly serve the settlement.

In other news, the creators of a chilling new horror game say that the title is so disturbing they've been forced tocensor it on PlayStation.

Applehas announcedupdates to AirTags following claims that the coin-sized tracking devices are being used to stalk people.

And TikTok has announcednew rules, banning users who deadname or misgender others.

Bzier Games recently revealed two new additions coming to the Maglev Metro series of games as we're getting Moonbases and Mars. As seen in the previous Mechs, Monorails, London, and Paris map expansions, these two will take the game in totally new areas as you head into space to create metro lines on the moon and the closest planet that might be able to sustain life. Each version has its own little tweaks, but they roughly play out the same for some fun with friends getting around the planet. No release date was confirmed beyond the fact they're coming out in 2022. Here's some added info from the team about both games.

Moonbases:Magnetic Levitation is the technology of choice for extra-terrestrial transportation, and your job is to build a network of intricate maglev rails to assist in creating a lunar vacation destination!

Mars:Maglev technology has enabled powerful ships arriving at Mars to build a colony there. The thin atmosphere and canals make building tracks a challenge, but the rewards for setting up a launch site to neighboring moons Phobos and Deimos make it all worthwhile!

WHILE Luke Skywalker peered at the two suns of his desert planet pondering his future as a Jedi, scientists peered back into the night sky wondering if such a planet could exist in the known universe and not just in a galaxy far far away.

Scientists have just confirmed that they've found such a planet and it's called Kepler-16b.

The exoplanet was spotted by a ground-based telescope located at an observatory in southeast France.

Professor Amaury Triaud, who led the team that found Kepler-16b, said: It is difficult to understand how circumbinary planets can exist.

"Thats because the presence of two stars interferes with the protoplanetary disc, and this prevents dust from agglomerating into planets.

Triaud theorized: The planet may have formed far from the two stars, where their influence is weaker, and then moved inwards in a process called disc-driven migration or, alternatively, we may find we need to revise our understanding of the process of planetary accretion.

that do push up against the traditional understanding of planet formation.

In 2019, a high school-aged intern named Wolf Cukier flagged what he thought was an eclipse.

Upon further investigation from his peers working on NASAs Transiting Exoplanet Survey Satellite (TESS), it turned out to be the first plant orbiting two stars discovered by the TESS program.

TESS would later discover a planet orbiting three suns in an extremely rare triple-star system.

Exoplanets, planets outside Earths solar system, existed only in theory starting in 1917.

The theory was confirmed in 1992 when astronomers Aleksander Wolszczan and Dale Frail discovered two planets 2,300 lightyears away.

Exoplanet.eu, a running catalog of all confirmed exoplanet discoveries, has nearly 5,000 entries to date.

The two planets Wolszczan and Frail discovered orbit a pulsarthe core of a collapsed star much larger than the Sun that supports the Milky Way.

Three years later, the first exoplanet orbiting a Sun comparable to ours was discovered.

The planet, Pegasi 51 b, experiences temperatures in excess of 2,000 degrees Fahrenheit due to its proximity to its star.

In other news, a huge explosion on the Sun could have been 'catastrophic' for Earth's power grid, experts have warned.

The Museum of the Future in Dubai is a time machine that shows visitors what life could be like in the year 2071.

From futuristic jobs faraway on a space station to how ecosystems can be saved 49 years from now the experience is entertaining as well as educational.

The two-hour experience is meant to be thought-provoking and leaves visitors wondering steps that can be taken now to create a better future.

The museum uses technology to represent art in the most remarkable ways, including screens with impressive graphics of a rocket launch and a DNA library that features more than 4,500 species.

An avatar called Aya guides visitors throughout their journey.

On Wednesday, a day after its official opening, The National went on a media tour of the museum. Here are five of the most interesting displays:

If you want to be an astronaut for a day, this is the experience for you.

It involves boarding a spacecraft called Hope, named after the UAEs Mars orbiter, and launching to the OSS Hope space station 600 kilometres above Earth.

Visitors are taken inside a room with metal walls, designed to look like a spacecraft, with screens all around that act as windows to show the stunning views during lift-off.

Aerial views of Dubais coastline, including The Palm Jumeirah, are visible, and then the delicate atmosphere of the planet, as the spacecraft enters space.

It is a four-minute experience that also shows the spacecraft docking with the OSS Hope space station.

Then, you enter the space station, where you learn about futuristic jobs astronauts can have in future, such as Mars colony ambassador to Earth.

The next part of the experience is the "heal institute", where you learn about nature.

A large screen shows the DNA of the Amazon, with footage actually filmed in the rainforest.

At Heal, we are working to repair the Earths natural ecosystems, with the help of artificial intelligence and biodesign, Aya says, as visitors enter the exhibition.

The Amazon is amazing. The forest generates half of its own rainfall by recycling water through trees.

Sadly, in some parts of the Amazon, years of deforestation have broken this cycle, changing huge parts of this ancient forest to dry savannah.

Another part of the Heal Institute is the DNA library, which has more than 2,400 models of species on display inside glass cases.

The colourful exhibition is meant to help visitors learn about different kinds of mammals, angiosperms, annelids and molluscs.

It is partially immersive, as visitors can collect a few species in a device given to them at the start and use it in the next exhibition to see how it could heal the ecosystem.

This is the Heal Observatory, where some species are grown in a nursery.

Visitors can release these species into the outdoors, including the ones collected in their device from the DNA library, to see how they behave and if the ecosystem heals.

It is an educational exhibition that would benefit researchers, as well as students and teachers.

Once the species are released, a large screen shows the progress being made in that ecosystem.

Al Waha is a futuristic spa, where visitors experience restorative effects of movement and meditation.

Visitors are welcomed with a vapour hand sanitiser that is blowing out of a structure that looks like a futuristic water fountain.

There is also a digital floor with a special carpet that gives the illusion of walking on a beach.

Few shows defined an era like Martin. From music to movies to fashion, the iconic sitcom was not only abroad mainstream hit, it was a cultural force that went beyond the screen and epitomized an era. The show was a crossover sensation all while providing an honest and refreshing view of the Black experience and to this day, the characters, all created by the comedic genius of the shows namesake, Martin Lawrence, are still some of pop cultures most beloved. Thirty years later, its legacy lives on, and this summer, fans will be able to relive all the love, joy and laughter as Martin and the gang come together once again for the first time in decades.

The reunion special, hosted by comedian and actor Affion Crockett, will include Martin Lawrence (Martin), Tisha Campbell (Gina), Tichina Arnold (Pamela) and Carl Anthony Payne II (Cole), along with surprise guest appearances. Taking a look at the shows origin and evolution, the reunion will feature interviews with the cast, original directors, special musical performances, and behind the scenes commentary on the importance and impact of the show that shaped a generation.

Martin is one of the most beloved sitcoms in our community, both because it is hugely entertaining and because it played a pivotal role in changing the narrative of Black voices in entertainment and in culture through the portrayal of young, ambitious Black leads and healthy Black relationships, said Scott Mills, CEO of BET. Decades later, that representation is still just as important, which is why were so excited to honor a series that put Black culture front and center on our platform that embraces Black culture everyday.

To be able to sit here thirty years later with this amazing cast that has had such an impact on pop culture is truly a blessing. I am always humbled that the fans still want more of the show and its characters. I am looking forward to the reunion special. said Martin Lawrence.

Martin is one of the greatest sitcoms of all time, said Jesse Collins, CEO of Jesse Collins Entertainment.JCE is honored to partner with Martin and BET on such an iconic reunion.

The reunion is executive produced by Martin Lawrence, Robert Lawrence, Rae Proctor and Stacy Lyles through his company Run Tel Dat Entertainment. For Jesse Collins Entertainment, Jesse Collins and Dionne Harmon serve as executive producers along with Jeannae Rouzan-Clay who is also the showrunner. The show is executive produced and directed by Stan Lathan. The special is written by Nile Evans as well as Bentley Kyle Evans who also serves as a co-executive producer. Jesse Collins Entertainments Brittany Brazil is a producer.

The taping took place Sunday, February 20 and will launch on BET+ later this year. In the meantime, fans can get ready for the reunion by re-watching all five seasons of Martin now on BET+.

By Jacco van Loon, Astronomer, Keele UniversityOf the eight planets in the Solar System, we live on Earth, and for good reasons. It has the perfect conditions for life.

Right now, though, we are sculpting Earth's surface by deforestation, and changing its atmosphere by adding carbon dioxide, methane and other greenhouse gases. These changes have resulted in global warming, which might lead us to worry that in the future, Earth may not be such a good place for us to live.

In our Solar System, the most similar planets to Earth are Mars, which is a bit further from the Sun, and Venus, which is a bit closer to the Sun. However, they are still very different to Earth.

There are a lot of ways in which these planets are different to Earth. One is the gases that are in the atmosphere. Both the atmosphere of Mars and that of Venus are mainly made of carbon dioxide. Neither planet's atmosphere contains any amounts of oxygen to speak of, which means that right now, we wouldn't be able to breathe on either planet.

Mars is generally considered the most promising planet to terraform. However, as well as being made mostly of carbon dioxide, the atmosphere on Mars is very thin. It doesn't press down on the planet with the same weight that the atmosphere on Earth does.

This pressure from the atmosphere is what keeps water on Earth liquid so we can drink it, and plants can use it to grow. Nearly all of the water on Mars is ice, except for a bit of water vapour in the atmosphere.

In order to create an atmosphere that we could breathe in, and to create enough pressure to keep water liquid, we would need to pump a lot of air into Mars' atmosphere a mixture of nitrogen and oxygen until the atmosphere was about as heavy as Earth's.

It might be possible to find this nitrogen and oxygen on Mars, which has soil that has been found to contain significant amounts of nitrate a molecule of one nitrogen and three oxygen atoms.

But there would be problems with doing this, including taking nutrients out of the soil that might be needed to grow plants.

Mars is also a very cold place, with an average temperature of about -60 degrees Celsius.

To change this, we would need to help its atmosphere trap heat. This is called the greenhouse effect. We could do this by pumping more carbon dioxide and methane into it (methane has been found on Mars). This would warm Mars and melt much of its ice, creating a water cycle like in Earth's climate. Mars would have seas, rivers and rainfall like Earth.

Mars or Venus?Alternatively, we could think about terraforming Venus. The gravity of Venus is quite similar to that on Earth, but for reasons not fully understood it has an atmosphere almost a hundred times heavier than Earth's. The weight of the atmosphere pressing down on us would crush us.

To reduce the weight of the atmosphere on Venus to be more like Earth's atmosphere, we would need to remove the carbon dioxide and some of the nitrogen.

Unfortunately, if we knew how to remove carbon dioxide from the atmosphere on such massive scale, we would be better off doing that on Earth in order to slow down global warming.

Mars and Venus have reached a natural state that differs from Earth's. If we turn them into Earth-like planets it means taking them out of balance. Left alone, they would change again. A terraformed Mars or Venus would require constant effort to maintain.

It would be far simpler and easier to build an artificial space colony, big enough to hold a whole ecosystem made up of plants, animals and other forms of life. We could then even possibly travel to another star system, where we might find a planet more like Earth. But we do not have the ability to do this, yet.

Until then, the best kind of terraforming would be to reduce humankind's imprint on Earth.

Could we change other planets in the Solar System so we could live on them? - Economic Times

If anyone is as bullish on the new frontier as China, it is the billionaires. Their ambitions, too, should spur NASA to stay in the game. Jeff Bezos and Elon Musk might or might not be visionaries, but they are easily the most powerful people on this planet to speak with a straight face about colonizing other ones. Mr. Musk warns of an extinction event that will require us to leave Earth behind. There is a certain egalitarianism in the idea of an escape hatch for humanity, though it is the egalitarianism of rats leaving a sinking (or overheating) ship. It would have to get pretty bad down here before ordinary people follow the billionaires into the black void of space rather than bid them adieu. Mr. Musks product placement of a Tesla in orbit and Mr. Bezos postflight performance in his cowboy hat leave one wary of their motives and nostalgic for the military bearing of Glenn. If space travel lost its novelty in the early 1970s, it might now be in the process of losing its dignity.

Of course, this takes nothing away from the achievements of Mr. Musks aerospace company, SpaceX. Rarely in any industry has such boldness of imagination been matched by such brilliance in execution. The company is an indispensable partner to NASA; a SpaceX landing system will carry astronauts to and from the moons surface.

But there is an essential difference between exploration and colonization, and both are a far cry from commercialization. Left to the billionaires, space is less likely to become a haven for humanity than a playground for its wealthiest members. In that event, there will be no more John Glenns no more astronauts to look up to and emulate, astronauts whose humility and awe in the vastness of space define them as much as their bravery does.

The exploration of space will go ahead, whether we join in it or not, Kennedy said in 1962 at Rice University, warning that no nation which expects to be the leader of other nations can expect to stay behind in this race for space. Perhaps this logic has lost its power; perhaps Americans dont care if the billionaires and China have the moon to themselves. The idea of space as a new frontier, too, might be tired, overworked. (During the Super Bowl, a Salesforce ad dismissed it with an Eh.) But the thrilling discoveries by Perseverance the evidence of ancient Martian river deltas and lava flows give eloquent testimony to the mysteries that await on the frontier. Robots like these are stunningly capable. Still, they cannot invent or imagine; they cannot drive the process of discovery in space any more than they do here on Earth. Only humans can lead, and to lead, humans must go.

Science is simply the exploration of the unknown, James Head, a planetary geologist at Brown who helped train the Apollo astronauts, told me, adding that the moon is unknown. Mars is unknown. Perhaps this is what NASA should say, and without apology: We dont know what well find. We dont know what the moon and Mars can tell us about the origins of the universe and life on Earth and possibly beyond it. And that, above all, is the reason for going. Six days after his return to Earth, Glenn addressed a joint meeting of Congress. What benefits are we gaining from the money spent? he asked, acknowledging that it was too early to say. But exploration and the pursuit of knowledge, he said, have always paid dividends in the long run usually far greater than anything expected at the outset. Why bother? This is why.
