The International Space Station is going to crash into the ocean. Here’s why: We’ve had this space house since 1998, where astronauts from around the world do science experiments in orbit. But it was only meant to last 15 years! Now, after more than 20 years, the ISS is… old. It’s getting expensive to maintain and needs periodic boosts to keep it in its orbit. So NASA and other international partners have officially decided that they will bring it down in 2030 - and replace it with something else.
