After four months in a mock space habitat in Hawaii, participants in a study to determine how best to feed astronauts (HI-SEAS) on a mission to Mars emerged yesterday. A few days ago, the mission commander was interviewed in Astrobiology Magazine, noting the most successful foods: "There's also been a lot of really good cooked dishes. Some of our crew members are accomplished cooks, and every week there are different surprises. Some success meals were Russian borscht, Moroccan tagine, enchilasagna, seafood chowder, and fabada asturiana. Wraps work really well: we combine tortillas, different vegetables, Velveeta cheese, and sausage or canned fish into ever-changing combinations. This is actually in line with the success of tortillas at the ISS. In general, the dehydrated and freeze-dried vegetables are a real success. They're used on a daily basis in almost every meal." The crew kept weblogs, and did other things than just sit around and eat: some studied robotics and they went on a few simulated EVAs.
