Suited for Spacewalking Educator Guide Introduction
Extravehicular activity, also known as spacewalking, began in the mid-1960s. Since then, astronauts have logged thousands of hours on EVAs, and some have even walked on the surface of the moon. The stories of their missions in space are fascinating, but almost as interesting is the spacesuit technology that made walking in space possible. This introduction explains the Suited for Spacewalking Educator Guide; briefly discusses how "a little bit of Earth" needs to be reproduced in space for astronauts to survive; and explains the space environment.
