Last year, NASA asked the public for help solving a problem facing its astronauts: how to collect and store poop in space. Now NPR reports that the five winners of the "Space Poop Challenge" have been announced, and their ideas are out of this world.

Astronauts currently rely on adult diapers when they need to do their business inside their space suits. As NASA wrote back in October: "After all: when you gotta go, you gotta go. And sometimes you gotta go in a total vacuum."

Looking for a more high-tech way to deal with these sticky circumstances, the space agency called on members of the public to submit designs for a system capable of collecting urine, feces, and menstrual fluid and routing it away from the body for 144 hours straight.

Close to 20,000 contestants submitted over 5000 ideas through the crowdsourcing site HeroX, and on Wednesday, February 15 five winners were revealed. Flight surgeon and family practice physician Thatcher Cardon was awarded the $15,000 grand prize for his ingenious waste-disposing suit hatch. Inspired by completing complex procedures in tight places as a surgeon, he designed a small airlock in the crotch for passing underwear, inflatable bedpans, and diapers in and out of the space suit.

The second-place team is made up of a physician, a dentist, and an engineering professor who all live in Houston, Texas and studied chemical engineering in college. Their "Air-PUSH Urinary Girdle" uses air to guide waste away from the body and stores it in a different part of the suit. The group, competing under the name Space Poop Unification of Doctors (or SPUDs), won $10,000 for the idea.

The third-place $5000 prize went to UK-based product designer Hugo Shelley for his "Zero Gravity Underwear." According to NPR, he says that the skin-tight undergarment "features a new catheter designed for extended use in microgravity, combined with a mechanism that compresses, seals, and sanitizes solid waste."

In perfect scenarios, astronauts would never spend anywhere near 144 hours in their suits and wouldn't need to worry about the question of long-term waste collection. The designs are more for disaster situations when crew members might find themselves stuck in their space suits for up to six days at a time. After building prototypes of the winning ideas, NASA next hopes to test the systems on the International Space Station.

11 Out-of-This-World Facts About Carl Sagan
Original image

Carl Sagan was perhaps America’s most beloved scientific visionary since Albert Einstein. Both a gifted astronomy researcher and an incredible communicator, he brought the wonders of the universe to the masses with his popular TV series Cosmos and books like the Pulitzer Prize–winning Dragons of Eden and Pale Blue Dot. His only novel, Contact, later became a sci-fi movie starring Jodie Foster and Matthew McConaughey. Here are a few things you might not know about the scientist, TV star, and amateur turtleneck model.

1. HARVARD PASSED ON HIRING HIM.

After Sagan served five years at the esteemed university as an assistant professor, Harvard denied him tenure in 1967, in part because one of his mentors at the University of Chicago derided his work as needlessly wordy and useless. He took a job at Cornell instead, where he stayed on as a professor until his death in 1996.

2. HE DICTATED ALL OF HIS WRITING TO AN AUDIO RECORDER.

Sagan was an avid self-editor. A total of 20 drafts of Sagan’s 1994 book Pale Blue Dot exist today in the Library of Congress, each filled with handwritten edits, annotations, and revisions by the author. However, he drafted all of his writing—even grant proposals—by dictating his ideas onto a cassette. The contents were then transcribed for him and returned for editing.

3. HE CONSIDERED WRITING A CHILDREN’S BOOK CALLED HOW DO BIRDS FLY?

In 1993, Sagan brainstormed a long list of possible children’s books for a series structured around the theme of “why?” Other potential ideas included Why Is It Warm In Summer?, Why Are There Lakes?, and What Is Air?

4. HE DIDN’T LIKE THE SPACE SHUTTLE PROGRAM.

Sagan argued against funding NASA’s Space Shuttle program in favor of more robotic exploration of the farther reaches of space. “That’s not space exploration,” he said in an interview about the space shuttle program’s week-long orbits. “Space exploration is going to other worlds.” A space station would only be worth it, he argued, if it was preparing humans for long-term journeys to space, he told Charlie Rose in 1995.

5. HE WAS AN EARLY CRUSADER AGAINST CLIMATE CHANGE.

Sagan’s 1960 Ph.D. thesis concerned the atmosphere of Venus. His theoretical model showed that the planet’s extremely high surface temperatures were due to the greenhouse effect of an atmosphere filled with carbon dioxide and water vapor. In his book Cosmos, he wrote, “The surface environment of Venus is a warning: something disastrous can happen to a planet rather like our own.”

6. HE HAS AN ARCHIVE IN THE LIBRARY OF CONGRESS ENDOWED BY THE CREATOR OF FAMILY GUY.

Family Guy creator Seth McFarlane put up an undisclosed sum to help the Library of Congress buy more than a thousand boxes of material kept by the late scientist and his wife and collaborator, Ann Druyan. The papers in The Seth MacFarlane Collection of Carl Sagan and Ann Druyan Archive, which opened in 2013, include some of Sagan’s earliest notebooks and report cards.

7. HE BECAME FAMOUS FOR A PHRASE HE NEVER SAID.

After Sagan appeared in several successful spots on the Tonight Show Starring Johnny Carson, Carson saw fit to send up the scientist’s signature style (turtleneck included) in a parody sketch.

Carson’s exaggerated use of “billions and billions” would later become associated with the astronomer, though he didn’t use it himself. However, Sagan did talk about large numbers quite a lot, as this supercut shows.

8. HE AND ANN DRUYAN DATED FOR ONE PHONE CALL—AND WERE ENGAGED BEFORE HANGING UP.

Sagan and Druyan, who would create the TV show Cosmos together, fell in love while working on the Voyager message. The courtship was exceedingly brief, as NPR's Radiolab describes:

“After searching endlessly for a piece of Chinese music to put on the record, Druyan had finally found a 2500-year-old song called ‘Flowing Stream.’ In her excitement, she called Sagan and left a message at his hotel. At that point, Druyan and Sagan had been professional acquaintances and friends, but nothing more. But an hour later, when Sagan called back, something happened. By the end of that call, Druyan and Sagan were engaged to be married."

9. HE WANTED TO LEGALIZE POT.

Under the pseudonym “Mr. X,” Sagan wrote a 1969 essay for Time magazine about the personal benefits he’d seen from cannabis use. Then in his mid-30s, he admitted to smoking throughout the prior decade. “I find that today a single joint is enough to get me high,” he wrote, going on to observe that marijuana had enhanced his appreciation for art and music. He concluded that “the illegality of cannabis is outrageous, an impediment to full utilization of a drug which helps produce the serenity and insight, sensitivity and fellowship so desperately needed in this increasingly mad and dangerous world.”

10. HE THOUGHT STAR TREK WAS TOO WHITE.

“In a global terrestrial society centuries in the future, the ship’s officers are embarrassingly Anglo-American. In fact, only two of 12 or 14 interstellar vessels are given non-English names, Kongo and Potemkin,” he wrote in a piece about the impact of science fiction on his life in The New York Times in 1978.

11. HE WANTED US TO LEAVE MARS ALONE.

Despite his passion for exploring space, Sagan argued for the preservation of Mars even if it meant limiting our exploration of the planet. In Cosmos, Sagan declared:

“If there is life on Mars, I believe we should do nothing with Mars. Mars then belongs to the Martians, even if the Martians are only microbes. The existence of an independent biology on a nearby planet is a treasure beyond assessing, and the preservation of that life must, I think, supersede any other possible use of Mars.”

Like many Americans, astronauts Randy Bresnik and Mark Vande Hei got up and went to work this morning. But instead of an office, their jobs took them on a walk outside the International Space Station. If that sounds more exciting than what you’re doing at the moment, you can watch their progress live on NASA’s website.

The spacewalk, which commenced the morning of October 5 at 8 a.m. EDT and is expected to last over six hours, is the first of three NASA plans to livestream during the month of October. On this mission, Bresnik, Expedition 53's commander, and Vande Hei, a flight engineer, are replacing one of the motorized lathes on the station’s robotic arm. The Latching End Effectors as they’re called are used to grab cargo vehicles and payloads that arrive at the station.

Bresnik has worked aboard the ISS since July and Vande Hei since September. The pair will don their spacesuits again for NASA’s second livestreamed spacewalk of the month on October 10. On October 18, Bresnik will be leading the third spacewalk and he’ll be assisted by flight engineer Joe Acaba. If you missed this event, you can follow NASA Live for more streams of spacewalks, cargo craft launches, and the occasional orbiter disintegrating in Saturn's atmosphere.
