Jemma and I went to see the Martian in 3D last night.
Really enjoyed it. It seems petty realistic. After the movie we had pizza and while we were waiting, checked a few "facts" on the net.
Turns out potatoes and poo is a viable choice on Mars.
Likewise a plutonium heater seems also plausable. I had assumed he would have gotten radioactive poisoning.
A "Sol" is indeed a martian day. Just over 24 earth hours.
Pondered what speed of rotation one needs on the Hermes space craft wheel to simulate gravity?
Can one really take off without a nose cone?
Why were the Chinese in the story?
