🌍 Space is a dangerous environment with no oxygen, dangerous radiation, and extreme temperatures.
👨🚀 Astronauts wear spacesuits made of strong material and filled with oxygen to survive in space.
🚀 Soviet Cosmonaut Alexi Leonov was the first person to walk in space in 1965, followed by astronaut Edward White.
🚀 Spacewalks during the Gemini 4 Mission proved that humans can survive in space.
🔧 Astronauts perform spacewalks to complete tasks that cannot be done inside the shuttle, such as repairing solar panels and building the International Space Station.
⚠️ Spacewalks are dangerous, but astronauts work in pairs and are connected to the spacecraft for safety.
👩🚀 Astronauts practice their spacewalks underwater at NASA's neutral buoyancy laboratory.
⌚️ For every hour spent walking in space, astronauts spend 10 hours practicing underwater.
🛰️ Spacewalks will continue to be important for the maintenance and construction of the International Space Station.
