NASA Kids Science News segment explaining how astronauts eat in space.
Hi, I'm Hannah, with another NASA fact.
00:00:00
Are there grocery stores in space?
00:00:06
Don't astronauts take all their food with them from Earth?
00:00:09
That would be hard to do for a six-month trip to Mars.
00:00:12
So what do they do?
00:00:15
Many kinds of food are freeze-dried.
00:00:17
That's when water is removed on Earth and added back in space.
00:00:19
The food lasts a longer time that way, and that would be good for a trip to Mars.
00:00:22
What other kinds of food are good for a Mars flight?
00:00:26
Astronauts need variety in their diet, just like we do.
00:00:29
Fresh vegetables are good choices.
00:00:32
We know most of what they will eat will be freeze-dried or prepackaged food.
00:00:35
They also can grow some fresh food on their way to Mars with hydroponics,
00:00:39
which uses water, not soil, to grow plants.
00:00:42
Will astronauts eat snacks like candy and potato chips?
00:00:45
That information, and more, is on our website.
00:00:49
Until next time, I'm Hannah, with cool NASA facts you can use.
