SOLAR SYSTEM

Detailed explanation-1: -A spacesuit protects astronauts from those extreme temperatures. Spacesuits supply astronauts with oxygen to breathe while they are in the vacuum of space. The suits contain water to drink during spacewalks .

Detailed explanation-2: -Space suits are often worn inside spacecraft as a safety precaution in case of loss of cabin pressure, and are necessary for extravehicular activity (EVA), work done outside spacecraft. Space suits have been worn for such work in Earth orbit, on the surface of the Moon, and en route back to Earth from the Moon.

Detailed explanation-3: -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.
