Nasa’s loo challenge: A toilet that works both in microgravity and lunar gravity

NEW DELHI: As Nasa prepares for its return to the Moon, innumerable activities to equip, shelter, and otherwise support future astronauts are underway.
To help austronauts while they are in the space, Nasa has launched a Lunar Loo challenge to call for novel designs for compact toilets. The space agency said that the designs have to be such that while astronauts are in the cabin and out of their spacesuits, they should be able to use the toilet in the same conditions as on Earth.
The US space agency has invited designs for developing toilets that not only work in microgravity but also in lunar gravity. Although space toilets already exist and are in use (at the International Space Station, for example), they are designed for microgravity only.
“These designs may be adapted for use in the Artemis lunar landers that take us back to the Moon,” Nasa said.
Nasa’s Human Landing System Program is looking for a next-generation device that is smaller, more efficient, and capable of working in both microgravity and lunar gravity. This challenge includes a “Technical category” and “Junior category”.
The challenge is being overseen by the Nasa Tournament Lab and organised on the HeroX crowdsourcing site. It is part of Nasa’s ‘Artemis’ programe to land the first woman and the next man on the Moon by 2024.
This Lunar Toilet Challenge has a total prize purse of $35,000 that will be shared among the teams submitting the top three designs in the Technical category.
The top three participants in the Junior category will each receive public recognition and an item of official NASA-logoed merchandise.
The deadline for the competition is August 17.
