This is how the astronauts live in space.
Chandrayan mission will create a history by landing on the moon surface on 23rd of August
Astronauts fly in the space due to no gravity in there.
They receive a special training for it and eat thermostablized food.
They drink a particular type of powder and eat nuts too.
Astronauts still need to do their everyday living, such as working, eating, relaxing and exercising, but with fewer resources than they have on Earth.
Astronauts usually sleep by restraining their bodies in a small sleeping compartment or sleeping bag in space.
