Mars mission will call on, not just Nasa, but the might of all nations

The Martian was a vision of the future, writes Nasa chief scientist Ellen R Stofan, but the real story of space exploration will be one of global collaboration with benefits for all of humanity

In The Martian, one of the hit films of 2015, Nasa heroically saves a stranded astronaut with a little help from international partners and a lot of human ingenuity.

Directed by Ridley Scott and starring Matt Damon and Jessica Chastain, the movie is visually beautiful, and provides nailbiting entertainment.
