What happens to astronauts poo in space?

Answer 1

During the Apollo missions, the CM and the LM each had a condom-shaped sleeve (technically, each astronaut had their own sleeve, which they would connect to the tube each time they needed to use the bathroom), connected by hoses and a valve to the exterior of the spacecraft. To urinate they slipped the sleeve on, relieved themselves, then opened the dump valve, expelling the urine into space.

To defecate, the astronauts had a sort of top-hat shaped container with an adhesive rim that they would attach to their buttocks, relieve themselves, then remove and seal. The container had a small capsule inside containing the familiar blue chemical found in airplanes lavatories. They would then squeeze the container to break the capsule and mix the chemical with the feces contained in the pouch. These pouches were stored until they could be disposed of back on Earth.
