As a food anthropologist, I am interested in the premise of a new movie hitting theatres this week. In the movie Martian, actor Matt Damon plays a botanist stranded on Mars tasked with figuring out how to survive as he awaits rescue- several years in the future! Of course a critical piece is going to be food: is the movie total sci-fi fantasy or grounded in scientific possibility? Here is an article you might enjoy that checks in to some of these plot lines. NASA is busily working on how to grow food in space as this is critical to space exploration in the future, keep your eyes open for more cool examples of this research.
