If you enjoyed participating in the Lunar Loo Junior Challenge, you're going to want to check out our latest NASA Junior Challenge - the Recycling Air Beyond Our Earth Jr. Challenge. Submissions are due in exactly one month, so get started on your submissions as soon as possible! Check out the challenge short description below.
When we breathe, our bodies take needed oxygen out of the air. When we exhale, our bodies release carbon dioxide back out. Usually, we don’t think about this because our planet has a breathable atmosphere. But in the future, humans may live in habitats on the surface of the moon and on other planetary surfaces. These places don’t have a breathable atmosphere, so human habitats will need a system that can maintain it for the crew. What’s your idea for how an extraterrestrial habitat can maintain a breathable atmosphere for its inhabitants?
