Pie in the sky? Mars Ice Home concept.
Elon Musk may be disappointed by recent studies threatening his plans to go to Mars, but planetary scientists are breathing a sigh of relief.
We can create the right kind of food plants to survive on Mars.
If humans are to live on Mars they will need a stable supply of food. Earth plants are not suited to the Mars climate but we can engineer plants that are.
Mars’ south polar cap, as seen from Mars Global Surveyor. Buried beneath, we now know, is a lake of liquid water.
Researchers have found evidence of a large lake of salty water, buried 1.5 kilometres beneath the southern polar ice cap on Mars. So what does that mean for life on the red planet?

The race may be on to send humans to live on Mars, but is it worth the effort -- and the spend -- when we have our own problems to deal with on Earth.

Clay on early Mars could have formed under hot and steamy conditions, challenging the idea that it was created just like that on Earth.
The Viking landers in the 1970s were the last to look directly for life on Mars.
Planetary protection protocols try to make sure we don't seed places like Mars with life from our planet. An astrobiologist argues they're misguided – especially with human astronauts on the horizon.

Will humans ever live on Mars? Whoever it is to get there first will benefit from the experiences of those who stayed in simulated Martian missions here on Earth.
Even if alien life is never discovered, all is not lost.
A view from the ‘Kimberley’ formation on Mars taken by NASA’s Curiosity rover. The strata in the foreground dip towards the base of Mount Sharp, indicating flow of water toward a basin that existed before the larger bulk of the mountain formed.
We could learn a lot from any mission to send people to Mars, such as whether there's life elsewhere in the universe or even the technology for new household appliances.

One of the best ways to find out the challenges of living on Mars is to simulate living on another planet here on Earth. So what's it like to spend several months living the Martian life?
Ridges in the Dresser Formation in the Pilbara Craton of Western Australia that preserve ancient stromatolites and hot spring deposits.
Life on the land could have started millions of years earlier on Earth than first thought. This could change the way we think about life developing elsewhere in the universe.
The HI-SEAS mission gives people a chance to practise on Earth what life would be like on Mars. A crew member here from the 2015 mission.

What's the best way to find out how people will cope with the journey to Mars and life on another planet? Lock a test crew up for a year in a simulation right here on Earth.
We’re on the hunt for life – what do we do when we find it?
A philosopher argues that now is the time to figure it out, before we make the inevitable discovery of extraterrestrial life.

If we do find life on Mars, it will be difficult to prove that we didn't bring it there from Earth. An insider talks us through what's at stake.
The ALICE detector at the Large Hadron Collider may help unravel some of nature’s grestest mysteries.
Our panel of experts speculate on which of science's biggest questions could be answered in the coming months.
Unlike science fiction films featuring grotesque aliens and faraway galaxies, Ridley Scott’s The Martian depicts a sci-fi space mission that could soon be science fact.

NASA has set a target date of 2030 for a manned mission to Mars. With no real scientific breakthroughs needed, success depends on developing the proper technology.
This digital false-colour image shows the dark, narrow streaks on Martian slopes inferred to be formed by seasonal flow of water on the planet. The streaks are roughly the length of a football field.

Now that we have discovered liquid water on the surface of Mars, what does this mean for the prospects of finding life there, past or present?
Something big has disturbed the red planet’s thin atmosphere.
Enormous cloud-like plumes reaching 260km above the surface of Mars have left scientists baffled. This is way beyond Mars’s normal weather, reaching into the exosphere where the atmosphere merges with…
Curiosity Rover has used its onboard lab to detect methane on the Martian atmosphere.
NASA has revealed that a whiff of methane has been detected twice in the last couple of years at the Martian surface by the Curiosity Rover. The source of the methane is uncertain. It is not even clear…
We have lift-off.
After a 24-hour delay due to bad weather, the first test launch of the Orion spacecraft by NASA is underway with the ultimate goal of putting human beings on Mars. Weeks after the landing on a comet by…
