The human experience of food extends far beyond that of mere nourishment. Debriefs with astronauts tell us that food is a key, creature comfort in spaceflight, and it will play an even more significant role on longer trips, such as a future voyage to Mars. Thoughtfully designed foods and culinary experiences will allow humans to feel more connected to their loved ones and histories on Earth. This will also help to promote the beginning of a food culture that fosters deeper relationships with new worlds.

The Space Exploration Initiative is developing a cookbook for zero gravity. It will document existing menu items and eating regimes developed by astronauts living in space, as well as new, speculative recipes that reflect a proposed future on new lands and new orbits.

Food touches all of us, and so we want to hear from you! This is our open-source community platform for Zero Gravity Cookbook.
