The toilet on the #ISS is made of a hose with a funnel for “no. 1” & a toilet seat with a solid waste container for “no. 2”. For both, the trick is... suction! To make sure things go in the right direction & to control odours, the first thing we do is to turn on the fan & the last thing we do is to turn it off! Urine is more than 90% water, so to avoid transporting lots of water from Earth, we recycle collected urine back to clean, drinkable water aboard the Space Station. #MissionMinerva
