I would definitely consider space food as its own cuisine. On Earth, cuisines are created when people from a region use generations or wisdom to flavor, to prepare and preserve the food. And because of unique challenges we're facing for space food, like we need to meet the safety standard, we need to meet the nutritional standard and the food ne... Read More

Questions & Answers

Q: How is space food different from regular food?

Space food must meet safety and nutritional standards while being able to work in a microgravity environment. It is either thermal-stabilized or freeze-dried and ready to eat.

Q: What role does food play in the mental well-being of astronauts?

Food provides critical mental well-being to astronauts, especially when they are far away from home. It serves as a reminder of celebrations and gatherings, bringing comfort and familiarity.

Q: How is space food supplied to astronauts on the International Space Station?

The International Space Station has over 200 different food and beverage items. Crew members undergo food session training to familiarize themselves with the standard menu, which is divided into categories for ease of access.

Q: What challenges does microgravity pose for space food?

In microgravity, water acts as a bonding agent, and crumbs or loose particles can float and interfere with equipment. Salt, for example, is dissolved in water and sent as liquid salt for use in the microgravity environment.

Summary & Key Takeaways

• Space food is created to meet safety and nutritional standards, as well as work in a microgravity environment.

• The food provided to astronauts is shelf-stable and can have a long shelf life, catering to their needs while far away from home.

• There are two major types of space food: thermal-stabilized food and freeze-dried food, both of which are ready to eat.
