They need to exercise with regularity because the muscles begin to atrophy and bones begin to lose density . This present shuttle mission to the International Space Station brought the C.O.L.B.E.R.T. ( named after the comedian) which is an acronym for Combined Operational Load Bearing External Resistance Treadmill ; see related links .
The body is wonderfully good at adapting to what it needs at the moment, and as you don't need much strength in weightlessness, you loselose strength from your muscles and your bones quite fast. Then when you get back to Earth you're weak as a kitten and everything becomes real difficult. By exercising in space you can trick the body not to lose that much strength, which helps you when you get back to Earth.
omg they go in a sleeping bag and they freakin tape their selves to the wall in a space ship do you peeps understand. for exercising they use only one tool the ergeometer witch they need to do for two hours.
Space suits: to protect astronauts from extreme temperatures, micrometeoroids, and provide oxygen. Extravehicular Mobility Units (EMUs): for spacewalks to enable astronauts to move and work outside the spacecraft. Tether systems: to keep astronauts connected to the spacecraft while working in space.
Yes, astronauts do need to do laundry in space. They typically wear their clothes multiple times before changing them and then use specialized equipment like a space washing machine to clean their clothes. Water is recycled and used for laundry to conserve resources on the space station.
Astronauts need helmets in space primarily to provide life support by supplying oxygen and regulating temperature. Helmets also protect against the vacuum of space, which can cause bodily harm due to lack of pressure. Additionally, they shield astronauts from harmful radiation and micrometeoroids. Finally, the helmet's visor helps protect their eyes from intense sunlight and glare in the space environment.
their suits are very heavy.
There's no gravity in space - this affects their muscles. Exercising keep the muscles toned.
Astronauts have work out machines to keep their muscles strong. They exercise every day.
no because they don't need that much energy <33
In a zero gee environment (weightlessness), the Human Body almost immediately begins losing muscle and bone mass. If they did not exercise, Astronauts returning from Space after a long stay on the Space Station would be unable to walk, and would have to be in a wheelchair for weeks before they could learn to walk again.
They need to take it with them. There is no oxygen in space

Astronauts require less sleep than normal; Theoretically because the astronauts always have to be alert in a dangerous setting like space.
food, water, shelter
I am not sure, ask NASA
To survive in outer space, a man needs to have oxygen, water, food, space suit, warm clothing. We would also need a gravitational force similar to earth's, otherwise we would suffer rapid muscle degeneration, and eventually death. This is why astronauts must constantly exercise in space.
You need space food to give nutrition to astronauts. They need energy to perform tasks thus need food.
