When you’re packing for a road trip, one of the most important details to consider is the kind of grub you’ll need to pack to snack on. When you’re packing for a space trip, well, it’s really not much different. All things considered.Watch NASA Edge’s Space Food Cookoff below to get a closer look at what cosmic cuisine actually consists of.Back in 2000, 16 volunteers from Cornell University dined exclusively on space food for 30 days to get a better idea of what picnicking on Mars would really be like.The space food diet consists primarily of vegan (no meat or dairy) foods and enough dishes for 10 days, alternated for variety. The dishes, all previously tested in weekly taste panels at Cornell, were plant-based foods that had to be tasty, nutritious and economical. They also had to be low in salt (because sodium from recycled urine in a space colony would be bad for crops), low in iron (for space adaptation), not labor-intensive (astronauts’ time is at a premium), and sparing in their use of any ingredients difficult to produce in a space colony (cargo weight also is at a premium). The menu also had to be derived from a very limited list of crops, mainly wheat, rice, soybeans and other vegetables that will be grown hydroponically in artificially lighted, temperature-controlled space farms.Is your stomach growling yet? Try the space food diet for yourself.
