List of International Space Station spacewalks
Key Facts
Stepping Out into Space!
Spacewalks, also called Extravehicular Activities (EVAs), are when astronauts leave the International Space Station (ISS) to work outside. Think of it like going outside for recess, but your playground is the entire Earth below! These brave explorers wear special spacesuits that are like tiny spaceships, keeping them safe and giving them air to breathe.
They float around, fixing things or adding new parts to the ISS, which is as big as a football field!
When Did This Amazing Idea Start?
The idea of working outside a spacecraft started a long time ago. The very first spacewalk happened in 1965, even before the ISS was built! Astronauts on different space missions began doing these amazing feats.
When the International Space Station started being built in 1998, spacewalks became super important. Astronauts had to go outside many, many times to connect all the giant pieces of the station together, like building with giant LEGOs in space!
Why Are Spacewalks So Important?
Spacewalks are like the ISS's maintenance crew! Astronauts go outside to fix anything that breaks, like a leaky faucet or a wobbly chair, but in space. They also add new tools and experiments.
Without spacewalks, the ISS wouldn't be able to keep running smoothly or do all the cool science it does. It's how they keep their home in space working perfectly, so they can study our planet and the stars.
What Do Astronauts Do Out There?
Astronauts on spacewalks do all sorts of jobs. They might be tightening bolts, replacing a camera, or installing a new science experiment. They use special tools that are tethered to them so they don't float away.
It takes a lot of practice to move around in space. They have to be very careful and follow instructions exactly. Each spacewalk is like a carefully planned mission to keep the ISS in tip-top shape!
