NASA's Space Poop Challenge

NASA issued a public $30,000 bounty "for fecal, urine, and menstrual management systems to be used in the crew’s launch and entry suits over a continuous duration of up to 144 hours." From the competition brief:

Current space suits are worn for launch and entry activities and in-space activities to protect the crew from any unforeseen circumstances that the space environment can cause. A crew member could find themselves in this suit for up to 10 hours at a time nominally for launch or landing, or up to 6 days if something catastrophic happens while in space.

The old standby solution consisted of diapers, in case astronauts needed to relieve themselves. However, the diaper is only a very temporary solution, and doesn’t provide a healthy/protective option longer than one day.

What's needed is a system inside a space suit that collects human waste for up to 144 hours and routes it away from the body, without the use of hands. The system has to operate in the conditions of space - where solids, fluids, and gases float around in microgravity (what most of us think of as "zero gravity") and don't necessarily mix or act the way they would on earth. This system will help keep astronauts alive and healthy over 6 days, or 144 hrs.
