Astronauts use specially designed toilet systems to go to the bathroom in space. Here’s how it works:

Toilet Design

Vacuum System: Space toilets use a vacuum to pull waste away from the body, since there is no gravity to do so.

Urine Collection: Astronauts have a funnel connected to a hose for collecting urine. The funnel is designed for both male and female astronauts, and urine is sucked away into a storage tank.

Solid Waste Collection: For solid waste, astronauts sit on a seat that has thigh straps to keep them secure. The toilet has a lid that closes over the seat to create a vacuum seal. Waste is collected in a bag that can be sealed and stored until it can be disposed of.

Hygiene and Disposal

Hygiene: Astronauts use wet wipes and no-rinse soap for cleanliness, as water usage is limited.

Disposal: Once the bags are full, they are stored until the spacecraft returns to Earth or they are disposed of in a controlled manner, often by sending them into the atmosphere to burn up.

Training

Before going into space, astronauts undergo training on how to use the toilet systems to ensure they are comfortable and familiar with the process.

Overall, while going to the bathroom in space is more complex than on Earth, the systems in place allow astronauts to manage their needs effectively.
