Astronauts go to bathroom just like everybody else. However, it can be tricky in space because gravity is so weak that people and objects appear to be weightless. It means that toilets cannot flush(冲洗) the same way that they do on Earth. So we have started a competition to get ideas from around the world to develop a new space toilet that would work aboard the International Space Station (ISS) as well as on Moon.
The competition, titled “NASA’s Lunar Loo Challenge”, has a total prize of $ 35, 000 to be shared by winning teams. Anyone above 14 can apply to this challenge, and the winning design will receive a $ 20, 000 reward. The second-place design will win $10, 000, and the third-place winner will win $ 5, 000.
The competition also includes a junior category(类别) in which anyone under the age of 14 can apply with their creative space toilet ideas. Winners in this category will receive public recognition and our souvenirs.
Toilet Design Requirements
Designs should take up no more than 1.13m3 of space.
The space toilet has to be able to hold at least 1.5kg human waste.
The final requirement is that the system must be able to get rid of the waste and be cleaned in five minutes or less.
We hope this challenge will result in new ways to deal with human waste in outerspace.
