On Wednesday morning, NASA rewarded five members of the public — two doctors, a dentist, an engineer and a product designer — for their creative ideas for how to poop in a spacesuit. Yes, it sounds a little bit funny. But unmet toilet needs could have life or death consequences for an astronaut in an emergency situation. That's why thousands of people spent tens of thousands of hours on the "Space Poop Challenge," brainstorming, modeling, prototyping and number-crunching to come up with a crowd-sourced solution to the problem of human waste in a spacesuit. Currently, astronauts on spacewalks rely on diapers, which is a feasible solution for only a few hours at a time. As we explained in November , NASA is imagining a situation where an astronaut is stuck in a spacesuit for days — like during an emergency on future Orion missions, which could take astronauts far from Earth. The super-portable-bathroom solution has to work quickly easily, in micro-gravity, without impeding movement, for
