To continue exploring space, carrying out experiments, and learning how to live in space.
No the astronauts wear their space suits when they are launched, but they remove them later.
what astronauts do to keep their mouth healthy is to brush their teeth obviously (and what do suits have to do with your mouth) NOTHING!
The answer is an umbilical cord. It keeps astronauts from floating out into the universe.
Astronauts on space missions use special heating systems in their spacesuits to regulate their temperature. These systems can generate heat to keep astronauts warm in the cold vacuum of space. Additionally, the spacesuits themselves are insulated to retain body heat and prevent it from escaping into space.
gravity and oxygen
by going in space!!
operate or work aboard space craft
i dont know, maybe they get scared or surpriced
Going into space is dangerous. A fair number of astronauts and cosmonauts have died during space missions and others have face with life-threatening situations. Astronauts go into space knowing that even a seemingly minor malfunction could prove fatal.
There's no gravity in space - this affects their muscles. Exercising keep the muscles toned.
they might be able to. that is not a very great question unless you are going into space
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.
