Okay kiddo, so have you ever heard of a spacecraft? It's like a big machine that can go up into space and travel around. Well, a statio is a special type of spacecraft that doesn't really move around too much.
It's kind of like a house in space! It stays in one spot and people can live inside of it for a long time. But why would people want to live in space?
Well, sometimes scientists or astronauts need to go up there to do experiments or study things. Living in a statio is a way for them to stay up there for a long time and do their work without having to travel back down to Earth all the time.
It's also a way for countries to work together on space missions. The statio is an international project, which means that people from lots of different countries helped build it and send people up there to live in it.
So, to sum it up: a statio is a big "house" in space where people can live for a long time to do science experiments or work together on space missions. It's like a really cool space hotel!
