A spacewalk — sometimes called extravehicular activity — is when astronauts leave the relative safety of their spacecraft for the vacuum of space. In the history of human spaceflight, spacewalks have only ever been performed by government astronauts, who use them as an opportunity to do repairs, perform maintenance, or to conduct scientific experiments. Spacewalks performed by NASA astronauts typically last between five and eight hours.
