How do astronauts dispose their garbage?
On the space station, astronauts currently squeeze their garbage into trash bags and, for temporary periods of time, store up to 2 metric tons of trash on board. They then send the trash out on commercial supply vehicles, which either reach Earth or burn up in reentry.
What does the ISS do with human waste?
On the ISS, feces is collected, treated to prevent bacterial growth, and later sent to burn up in the atmosphere like a shooting poop star. So solid human waste is not recycled at the moment, though there’s talk of eventually using feces to line the walls of future space missions as a radiation shield.
Can we dump waste in space?
There are a couple of problems with the idea of launching garbage into space. The first would be that we would have to make sure that it was launched directly into the sun, otherwise, it would end up in the earth’s outer atmosphere. Some of this space trash is so low that it can actually re-enter earth’s atmosphere.
Why don’t we shoot nuclear waste into space?
Why can’t radioactive waste be sent in space? In short, its unfeasible, unpractical, dangerous and extremely expensive. Its estimated that the cost of launching material on a space shuttle costs ($22,000/kg). This is because of the immense thrust required, and we have not yet perfected our rocket fuel.
What health issues can astronauts have in space?
Increased risk of cancer and degenerative diseases, such as heart disease and cataracts, have been observed in human populations exposed to radiation on Earth. Health risks for astronauts from radiation exposure in space are mainly driven by long-term impacts.
