It’s no secret that humans poop — even in space. 

But the actual, physical act of going to the bathroom while floating in space can be tricky, to say the least. In a new contest, NASA is calling on innovators from around the world to develop a new space toilet that would work not just in microgravity such as aboard the International Space Station, but also in lunar gravity aboard a future lunar lander as part of NASA’s Artemis program which aims to return humans to the moon by 2024. The contest has a total prize purse of $35,000 to be shared by winning teams.
