Tiangong-2

Tiangong-2 is like a super cool space house that China built that can fly around in space. It's like a really big airplane, but it doesn't have wings, and it stays up in the sky all the time! Inside the space house, there are rooms where astronauts can sleep, eat, and do experiments. There's even a bathroom!

Scientists use Tiangong-2 to learn more about space and how to live in it. Sometimes, astronauts go outside of the house to fix things or do experiments. Sometimes, scientists from Earth talk to the astronauts using special phones.

Overall, Tiangong-2 is like a fancy clubhouse for astronauts. They get to hang out in space and learn cool things while they're up there. It's a really important adventure for China and for science as a whole!
