Extravehicular Activity: Adventures in Space!

When astronauts go on an adventure outside their spaceship, it's called an Extravehicular Activity, or EVA for short! Think of it like a spacewalk. They have to wear special suits that are like tiny spaceships for their bodies. These suits keep them safe and give them air to breathe, because space has no air at all! It's a super important part of exploring the universe.

The first person to ever go on a spacewalk was a brave astronaut named Alexei Leonov. This happened a long, long time ago, in 1965! He floated outside his spaceship for about 12 minutes. Later, Neil Armstrong took his famous 'one small step' on the Moon in 1969, which was also a type of EVA. Women also started doing spacewalks, like Svetlana Savitskaya in 1984!

Astronauts go on spacewalks for many reasons. Sometimes they need to fix things on the outside of their spaceship or space station, like fixing a broken window or a loose part. Other times, they are exploring new places, like the Moon! It’s like being a super-mechanic or explorer, but in space. These adventures help us learn more about space.

The special suits astronauts wear are called space suits. They are like a personal spaceship! They have air to breathe, they keep astronauts warm or cool, and they protect them from tiny bits of space dust. Some spacewalks use a long cord, like a leash, to keep the astronaut attached to the ship. Others use a special backpack that lets them fly around a little bit!
