However, NASA has had success with growing vegetables on the International Space Station with the space agency’s Veggie experiment.
Through that research, astronauts have been able to grow — and eat — plants on the ISS.
Can astronauts grow food in space?
The Vegetable Production System, known as Veggie, is a space garden residing on the space station. Veggie’s purpose is to help NASA study plant growth in microgravity, while adding fresh food to the astronauts’ diet and enhancing happiness and well-being on the orbiting laboratory.
What happens to food in space?
This is because astronauts can’t sprinkle salt and pepper on their food in space. The salt and pepper would simply float away. There is a danger they could clog air vents, contaminate equipment or get stuck in an astronaut’s eyes, mouth or nose. Astronauts eat three meals a day: breakfast, lunch and dinner.
What plants can grow in space?
But astronauts have grown several varieties of lettuce, radishes, peas, zinnias, and sunflowers, and they do just fine. “Plants are very adaptive, and they have to be—they can’t run away,” says Gioia Massa, a scientist at NASA’s Kennedy Space Center who studies plants in microgravity.
Can seeds survive in space?
The conditions in the vacuum of space are quite harsh compared to Earth. Seeds in space must be able to withstand large doses of ultraviolet and cosmic radiation, low pressure and microgravity. Believe it or not, the first space travelers were seeds.
