Apollo Astronauts Unload

Have you ever wondered what happens to waste matter in space? Not trash, but human waste, like pee and poop. On the Apollo missions, the astronauts left poop on the moon!

Amazing But True!

Astronauts on the manned Apollo missions were in space for 8 to 12 days. During that time they ate and drank, so certainly they needed to eliminate waste! Of course, NASA wanted to be sure it was done safely. There are two ways to deal with waste: The astronauts could eliminate waste into a bag and then dump it later. Or they could pee directly into space. That’s what they did! Poop couldn’t go directly into space so it was bagged. Where are those bags now?
