๐ Space is a dangerous environment with no oxygen, dangerous radiation, and extreme temperatures.
๐จโ๐ Astronauts wear spacesuits made of strong material and filled with oxygen to survive in space.
๐ Soviet Cosmonaut Alexi Leonov was the first person to walk in space in 1965, followed by astronaut Edward White.
๐ Spacewalks during the Gemini 4 Mission proved that humans can survive in space.
๐ง Astronauts perform spacewalks to complete tasks that cannot be done inside the shuttle, such as repairing solar panels and building the International Space Station.
โ ๏ธ Spacewalks are dangerous, but astronauts work in pairs and are connected to the spacecraft for safety.
๐ฉโ๐ Astronauts practice their spacewalks underwater at NASA's neutral buoyancy laboratory.
โ๏ธ For every hour spent walking in space, astronauts spend 10 hours practicing underwater.
๐ฐ๏ธ Spacewalks will continue to be important for the maintenance and construction of the International Space Station.
