SpaceX Addresses Leakage Issues on Crew Dragon Toilet Before Weekend LaunchSpaceX's Crew-3 mission is set to lift off on Sunday.

Most people don't think twice about going to the bathroom, but when you're going to space, a faulty toilet can be a critical issue — which is exactly the problem SpaceX Crew Dragon is fixing ahead of its weekend launch.

During the craft's Inspiration4 mission in September, the capsulealerted astronautsthat the toilet wasn't working properly. The crew found that the problem had to do with the toilet's fan, which is essential in proper suction of human waste.

"There's a storage tank where the urine goes to be stored [and] there's a tube that came disconnected or came unglued," SpaceX head of mission assurance William Gerstenmaier toldCNN. "That allowed urine essentially to not go into the storage tank, but essentially go into the fan system."

Although the four astronauts didn't notice at the time, the SpaceX team later observed contaminated areas on the floor.

This particular capsule is still at the International Space Station and is set to return next month. Now, SpaceX crew are testing to make sure the leakage hasn't dangerously corroded the contaminated areas.

"We'll double-check things, we'll triple checks things, and we got a couple more samples we'll pull out of the chambers and inspect," Gerstenmaier added. "But we'll be ready to go and make sure the crew is safe to return."
