Instant Genius: Mars

NASA is sending another rover to search for signs of life.

Following the ‘virtual construction’ stage, the competing teams faced each other in a final ‘build-off’.

Mars Express images suggest liquid water once flowed freely carving out valleys up to 200km across and 200m deep.

The hunt for life on Mars is one of the hottest topics in astronomy right now. But one scientist thinks that we already found evidence of microbes, back when the Viking landers touched down in the 1970s.

By drilling into the surface of Mars, NASA's InSight mission could help us discover more about the structure of the Red Planet, and maybe help us understand the formation of other planets.

Moving to a planet with reduced gravity and cosmic radiation will present some challenges. And did we mention that the very ground beneath your feet could poison you?
