The space agency has set an ambitious goal to send astronauts back to the moon by 2024 and the crew will obviously have to go to the bathroom during the mission.
Toilet designs should also save water and “help maintain a virgin environment inside the deodorant that is free of odors and other contaminants.”
“The bonus points will be awarded to projects that can vomit without requiring the crew member to put his head in the toilet,” the instructions said.
It should be able to support a crew of two astronauts for 14 days and allow the transport of waste to be stored or disposed of outside the vehicle.
The toilet must be easy to clean and maintain and must have a recovery time of five minutes or less between uses. It should also use less than 70 watts of power and make less noise than an average bathroom fan.
Space will also be an issue, so the toilet must weigh less than 33 kilograms on Earth and be less than 0.12 cubic meters in volume.
The top prize is $ 20,000 and the winners of the second and third place will receive $ 10,000 and $ 5,000. The deadline for submitting plans is August 17 and the winners will be announced in October.
