If you've seen, read, or heard about "The Martian" film or novel, you may know that it's a story by an engineer about survival on Mars. If you'd like some background on how author Andy Weir tried to make the story realistic, using known science, check out his talk at NASA's Ames Research Center at: https://www.youtube.com/watch?v=KBtXuBuZPpQ
The image accompanying this post is a selfie of a real "martian" -- the Curiosity Rover on Mars, which took the pictures from which this great Mars image was assembled in August. If you click on the picture, you get a bigger version.
