The Evolution of Space Food: From Pureed Tubes to Cultural Delicacies
TLDR Scientists have overcome the challenges of eating in a zero-gravity environment by developing pureed food in toothpaste tubes, freeze-dried and rehydratable foods, and even refrigerators and freezers in space. Astronauts now have the ability to bring their own cultural foods to space, but future missions to Mars will require new methods of crop production and food storage.
Timestamped Summary
00:00
Scientists initially didn't know if it was possible for humans to eat in a zero-gravity environment, but they eventually overcame the challenges and figured out how to make certain foods edible in space.
01:26
In the early days of space travel, scientists weren't sure if it was possible for astronauts to eat in a zero-gravity environment, but they eventually developed a plan to provide pureed food in toothpaste tubes that could be consumed through a straw.
02:37
During early space missions, astronauts consumed pureed food in toothpaste tubes and experienced motion sickness, with 75% of astronauts experiencing space adaptation sickness, leading to the development of dehydrated powders and freeze-dried foods that were difficult to rehydrate and didn't taste good.
03:50
During the Gemini and Apollo programs, astronauts were given freeze-dried and rehydratable foods to eat in space due to the potential dangers of crumbs and the need for food preservation.
05:03
During the Skylab program, astronauts were able to have a greater variety of foods, including perishable items, thanks to the introduction of a refrigerator and freezer, and the Soviets even grew their own food on their space station.
06:20
Astronauts from different countries have brought their own cultural foods to space, such as sushi, ramen, coffee, kimchi, and moose jerky, but creating versions suitable for space often requires significant development and cost, and astronauts can now request specific foods for their missions.
07:38
A mission to Mars will require the development of new methods of crop production and food storage, as astronauts will not be able to be resupplied and may need to grow food on Martian soil.
