Spacewalks are possible through the use of specialized suits called Extravehicular Mobility Units (EMUs) that provide astronauts with oxygen, temperature regulation, and protection from the vacuum of space. Astronauts are tethered to the spacecraft to prevent them from floating away, and they use handrails and footholds on the spacecraft to navigate. Training and preparation are essential for astronauts to safely conduct spacewalks.
