How do we protect astronauts from the extreme temperatures in space?

Space travel presents a series of challenges in harsh environments. The time it takes humans to survive is not long if pushed into space without wearing protective gear.

A space suit is a garment worn to keep humans alive in the harsh environments and temperatures of space.

Spacesuits are typically worn inside spacecraft as a safety precaution in case of loss of cabin pressure and are required for activities outside the spacecraft.

An independent oxygen supply and temperature control system equipped inside the suit allows the astronaut complete freedom of movement without dependence on the spacecraft.
