An anonymous reader writes: Sciencemag has an interview with the people behind the movie The Martian. Director Ridley Scott, author Andy Weir, and Jim Green, NASA's director of planetary science and an adviser on the film talk about the technology and the science in the movie. Scott says: "Almost immediately [after] I decided to do it, we started to have conversations with NASA about process, the habitats, the Mars Ascent Vehicle (MAV), the suits and everything. And they sent us pictures, almost like photographs, of what they hoped it would all be. If there had been anything in [the screenplay] that actually was suspect—they are not shy—they would have said so."
