Now the equipment has been improved a lot, and the problem of discharge and delivery has been solved very well. Even female astronauts can use it with peace of mind without worrying about being "ugly".
The astronauts' feces are brought back to Earth for testing, and the urine is sent out of the capsule.

Anonymous users2024-01-21As we said earlier, there is no gravity in space, so the problem with doing anything in a weightless environment is that objects will fly around and bounce if they are not secured. And this kind of problem can also occur in the toilet of the space, and it is extremely uncomfortable to think about such a scene.

The design of the toilet seat allows astronauts to choose their own position at will. The advantage of this set of equipment is that, at least on the shuttle, it is possible to urinate standing up. A funnel device on a set of hoses allows astronauts --- male or female to urinate standing up.
If they prefer, they can sit and untie their hands, they just need to connect it to the toilet with a swivel bracket. The system separates the solid and liquid excreta, which is flattened and left on the aircraft to be unloaded after landing. Liquid excrement is spilled into space.
NASA hopes to one day recycle this waste.
Researchers at the University of Guelph in Canada say reuse is crucial to addressing astronauts' diets in future space operations on Mars. The air utilized by the shuttle's toilet system must be filtered to remove odors and bacteria before returning to the living quarters.
ISS astronaut excrement was brought back to Earth by Progress.
On the International Space Station, the basic principle of the toilet is the same. A fan-powered airflow toilet system stores excreta. The urine is absorbed and stored in a 20-liter container before being poured into the "Progress" supply spacecraft.
Subsequently, the supply ship entered the atmosphere and burned up there.
As for solid waste, it is collected through a plastic bag with holes in the toilet. The airflow passes through these holes and collects all the excrement into the bag. Subsequently, the elastic top end of the plastic bag will be closed and pushed into a metal container.
The development of space toilets has been around for a long time. In the book "Space Pioneer" and its film version, an astronaut on an early space mission wants to urinate during a greatly delayed takeoff. With no facilities available, and no adult diapers that are now widely used during take-off and landing, he was eventually allowed to urinate in his spacesuit, causing problems with the sensors.

With the large-scale spacecraft and the improvement of environmental control systems, astronauts can eat without helmets or even spacesuits. On the Skylab orbital station in the United States, in addition to heaters for serving hot food, there are also refrigerators. The shuttle's galley has been able to store more than 100 kinds of food, and the crew can eat different meals every day. >>>More
There is a special toilet. It can be recycled and will not pollute space. >>>More
1. The problem of space catering
First of all, let's talk about their food, generally speaking, their food has been transported by the freight warehouse half a month ago. In the early days, astronauts' food would be made into the shape of toothpaste, but now astronauts in space eat everything from grilled fish to spicy snacks to yogurt and chocolate. >>>More
