spacewalk
Quick Summary
A spacewalk, also known as an extravehicular activity (EVA), is a period when an astronaut performs tasks outside of a spacecraft while in space. The first spacewalk was conducted in 1965 by Soviet cosmonaut Aleksey Leonov. Spacewalks are crucial for tasks such as spacecraft repair, scientific experiments, and assembly of structures in orbit. Astronauts are tethered to their spacecraft for safety during these activities. The environment of space presents significant challenges, including microgravity, extreme temperatures, and radiation, requiring specialized suits and extensive training for astronauts.12345
