No , but for astronauts visiting from other nations they do need passports to travel to the respective countries who are launching them into space e.g. the U.S. , Russia .
No, but here are strict rules on what they can carry with them.
Astronauts require less sleep than normal; Theoretically because the astronauts always have to be alert in a dangerous setting like space.
their suits are very heavy.
Most astronauts have to go to the hospital anyways for a check up before they leave for space. Some astronauts get hurt or injured n space and may need to get tothe hospital when they return. When astronauts get back they have an examination too. Astronauts are highly trained, but they are still human and can get sick or injured like anyone else.
You need a passport to cross from America to Canada. While inside Canada, you don't need your passport, except for ID purposes.
Astronauts wear special costumes, commonly referred to as "space suits" that protect them from the rays of the sun and gasses depending on which planet they are on. Space suits are airtight and also keep them warm while in the freezing vacuums of space, and cool inthe scorching sun. They wear a tinted glass for their face, not to be blinded by the glare.
If the space station is pressurized, I don't think astronauts need to where space suits.
They need to take it with them. There is no oxygen in space
No, astronauts actually don't do laundry in space. They have to throw away there clothes after they get dirty, because their is no way to wash them.
The reason it is so cold in space and astronauts need warm clothing is because thair is NO element in space for warm energy conduction, an element is any natral mass.
food, water, shelter
I am not sure, ask NASA
No, because most astronauts just make it into space but don't walk on the moon and their still considered astronauts.
Astronauts require less sleep than normal; Theoretically because the astronauts always have to be alert in a dangerous setting like space.
You need space food to give nutrition to astronauts. They need energy to perform tasks thus need food.
astronauts lose bone muscle because they are not used to the gravity conditions in space. They will also lose muscle and need to excersing while in space and also before leaving Earth.
their suits are very heavy.
