Astronauts, Or Cosmonauts if you're Russian, Wear spacesuits in outer space because there is no Oxygen to breathe out in the inky vacuum of space. It is also very cold in space and the suits help keep the astronauts warm,they also offer various facilities for an astronaut. Such as communication devices to speak to each other or to their ship or base back on earth.
Astronauts have to wear spacesuits when they leave the atmosphere due to lack of oxygen.
According to NASA, there are two reasons why astronauts wear white. First, white helps keep astronauts cool. Dark colors absorb a lot of light, which changes from light energy to heat energy.
because it is the most likely to zero gravity...
Space ships are pressurised and contain their own atmosphere of either oxygen or air (NASA uses oxygen, Russia prefers air). When astronauts have to go outside the ship, they wear spacesuits which are essentially personal spacesuits with their own oxygen supply.
