Space Food: A History of Feeding Astronauts in Space
The Early Days of Space Food
In the early days of space travel, astronauts’ food options were limited and unappetizing. Freeze-dried ice cream was a popular choice, but it was more of a novelty than a nutritious meal. Other menu items included corned beef sandwiches, which were smuggled aboard by astronauts, and instant breakfasts.
The Challenges of Feeding Astronauts in Space
Feeding astronauts in space presents unique challenges. Knives and other sharp objects are not allowed, as they could puncture equipment and create a hazard. Packaging and utensils must be designed to avoid creating sparks in the oxygen-rich environment of a spacecraft.
Another challenge is the lack of gravity in space. This causes fluids to pool in the head, which can lead to congestion and a diminished sense of taste. As a result, astronauts prefer foods that are highly seasoned and flavorful.
The Evolution of Space Food
Over time, space food has evolved to become more nutritious and palatable. Freeze-dried meals have been replaced by more recognizable dishes, such as spaghetti and meatballs, shrimp cocktail, and teriyaki beef. There is also a greater variety of vegetables and fruits available.
The Role of Food in Astronaut Psychology
Eating is an important ritual for astronauts, both physically and psychologically. It provides them with essential nutrients, but it also helps them to feel connected to Earth. “We try to make the food emulate Earth food as much as possible,” says Vickie Kloeris, NASA’s manager of food systems for the International Space Station. “It keeps them connected.”
The Future of Space Food
As astronauts embark on longer missions, the need for nutritious and varied food will become even greater. NASA is working to develop new food technologies, such as 3D printing, that will allow astronauts to create custom meals in space.
How to Eat Like an Astronaut
If you’re curious about what astronauts eat, there are a few ways to try it for yourself. Freeze-dried meals are available for purchase online and at some specialty stores. You can also find recipes for astronaut-inspired dishes online.
Specific Examples of Space Food
- Beef-barbecue cubes: These were a popular choice on early Apollo missions, but they were later discontinued because astronauts found them to be too dry and chewy.
- Fruitcake: This classic holiday treat has also been a staple of space food for many years. It is a high-calorie food that provides astronauts with a quick energy boost.
- Coffee with cream and sugar: This is a favorite beverage among astronauts, and it is often used to help them wake up in the morning.
Conclusion
Space food has come a long way since the early days of freeze-dried ice cream and corned beef sandwiches. Today, astronauts have a wide variety of nutritious and flavorful food options to choose from. As space travel continues to evolve, so too will the food that astronauts eat.
