Different suits serve different purposes

Space exploration includes two kinds of spacesuits:

• One is worn inside a spacecraft during launch and ascent to space, during re-entry into Earth’s atmosphere and during landing.
• The other kind is designed specifically for spacewalks. NASA calls a spacewalk an Extra-Vehicular Activity or EVA, so this type of suit is called an EVA suit. It is a miniature spaceship shaped like a human body that protects from dangers such as radiation, dust, debris, and extreme temperatures.
