SOLAR SYSTEM

Detailed explanation-1: -The suits protect astronauts from getting too hot or cold. Spacesuits also give astronauts oxygen to breathe while they are working in space. The suits hold water to drink. They also keep astronauts from getting hurt by space dust.

Detailed explanation-2: -The spacesuit worn for spacewalks outside the International Space Station is called the extravehicular mobility unit, or EMU.

Detailed explanation-3: -When on a spacewalk, astronauts use safety tethers to stay close to their spacecraft. Tethers are like ropes. One end is hooked to the spacewalker. The other end is connected to the vehicle.

Detailed explanation-4: -Also because of the lack of atmosphere, the astronauts would be subjected to extreme temperatures in outer space. Hence space suits are designed to protect astronauts against extreme heat and cold.

Detailed explanation-5: -Because an Earth-like environment is created within the suit itself, a space suit allows you to walk around in space in relative safety.

Detailed explanation-6: -The astronauts don’t walk, but hover, float, and pull to move around. To make sure the astronauts don’t float away, they are attached to their spacecraft by a safety tether (rope). About 200 astronauts have spacewalked, making more than 700 individual walks between them, usually to work on their craft.
