Space Training
This is the bathroom of the Space Shuttle Columbia.
This is the bathroom of the Space Shuttle Columbia. In the center of the picture, the toilet bowl and the urine funnel -- gray tube -- are visible. The astronauts have to position themselves on the toilet seat, using leg-restraints and thigh-bars. The toilet basically works like a vacuum cleaner with fans that suck air and waste into the commode. Each astronaut has a personal urinal funnel, which has to be attached to the hose's adapter. Fans suck air and urine through the funnel and hose into the wastewater tank.
