Well kiddo, did you know that when astronauts go to space, they can't just go potty like they do on Earth? That's because there is no gravity in space, and things don't work the same way as they do back home. So, when they have to go, they have to do it in a special toilet that sucks everything into a container.
But, as you can imagine, having poop floating around in space can be pretty dangerous! So, NASA has a Space Poop Challenge to find a new way for astronauts to go potty in space that is safe and comfortable.
Some people who are really good at inventing things are working on creating new types of space toilets. They have to think about things like how to keep everything contained so it doesn't float away, and how to make sure the astronauts don't get poop on their suits!
It's a really important challenge because if we want astronauts to go on long space missions, like to Mars, we need to make sure they have a safe and comfortable way to go potty. So, scientists are working hard to come up with the perfect space toilet for our space explorers.
