Any time an astronaut gets out of a vehicle while in space, it is called a spacewalk. A spacewalk is also called an EVA. EVA stands for extravehicular activity.
The first person to go on a spacewalk was Alexei Leonov. He was from Russia. The first spacewalk was on March 18, 1965. It was 10 minutes long.
The first American to go on a spacewalk was Ed White. His spacewalk was on June 3, 1965, during the Gemini 4 mission. White's spacewalk lasted 23 minutes.
Today, astronauts go on spacewalks outside the International Space Station. Spacewalks usually last between five and eight hours, depending on the job.
Americans on the International Space Station have scheduled a 6.5-hour spacewalk and you can watch it live on NASA TV.
Drew Feustel and Rick Arnold are part of NASA's Expedition 55 to study Earth atmospherics, the effects of microgravity on bone marrow, materials’ responses to space environments, and biological samples’ responses to simulated gravity," according to the mission summary.
