Read the book: "The Martian" by Andy Weir. Research crew of 6 lands on Mars for a 40 day exploration.
REALLY bad sandstorm threatens their escape vehicle. No lifesigns transmitted from 1 crew member.
So the other 5 take off for Earth. But, he's not dead yet. Extraordinary piece of bushcraft.
Soon to be a movie with Matt Damon playing the eponymous Martian.
The Road, grim reading the film managed to bring the book alive. Post apocalypse films tend to ignore key facts with maguffins though. With the Road it was evident that foraging for food is hard, the treat of your first cola though...
I enjoyed the film, however the book is better (and bleaker).
If folks are going to add disaster books to the thread then I'll mention 'Seveneves' by Neal Stephenson, which I'm about three quarters of the way through.
A brief synopsis would be, the world is going to end. Everyone knows it. It will end completely (and suddenly), nothing will be left on the surface, no structures and no life. The planet will be uninhabitable for several thousand years at least.
Humanity has about three years to prepare for the end, the available technology is little advanced from what we know, is three years enough to get a viable human population off world along with everything they will need to keep them ticking over for a few millennia?
You'll have to read the book to find out, but be warned this isn't Star Trek.
You can read the first chapter
