The four space probes on the Artemis II mission have had a quiet journey so far. Very few in-flight problems have arisen to disturb their peace of mind.
Except, that is, for the bathroom.
The Artemis II crew’s 16.5-foot-wide (5-foot-wide) Orion capsule has a problem related to waste management that appeared in the early hours of Saturday as Day 3 was winding down.
“It’s a matter of flushing the waste down the toilet,” Artemis II Flight Controller Judd Frieling told reporters Saturday morning. And so it looks like we may have frozen urine in the airway.
The astronauts – NASA’s Reid Wiseman, Victor Glover and Christina Koch and Canadian Space Agency astronaut Jeremy Hansen – were still asleep around midday about 200,000 miles (about 320,000 kilometers) from Earth as mission commanders continued to solve the problem. And at 3:30 pm ET Saturday, early in Day 4 of the flight, mission commanders had a plan of attack: to heat the frozen cable by rotating the capsule to inject frozen urine into the sun. That blocked the tube, allowing the waste system to flush the urine out of the capsule, which is an opportunity to cleanse the system. allowing the astronauts to start using the toilet again.
Shortly after trying to pass some urine, mission control said the toilet was “running” – but “for excrement use only.”
The process of getting the urine out of the capsule was a moment Koch also showed the camera earlier in the work. Pee flows like sparkling jewels in the void as it approaches Orion’s windows.
The crew also reported a burning smell coming from the bathroom, although mission commanders noted that it could be the material of the gasket around the door.
But this is not the first time the workers have encountered toilet problems.
Shortly after liftoff from NASA’s Kennedy Space Center in Florida on Wednesday, the crew noticed that the toilet pump was not working. Pumps are important and used for a variety of reasons, including helping with the removal of waste from the body. In space, there is no gravity that can help with such expulsion.
That problem had a relatively straightforward fix: The crew wasn’t putting in enough water to run the pump. After they improved, the system started working as planned.
Astronomers celebrated that small victory Thursday during a candid interview with the media.
“I’m proud to call myself a local piper,” Koch said. We all breathed a sigh of relief when things seemed to be going well.
“Luckily, we’re all gone,” he said.
The cockpit is perhaps the most popular spaceship space for astronauts who value creature comforts.
“I’d say it’s probably the most important piece of equipment on board,” Koch added during Thursday’s launch from Orion.
Because of Orion’s malfunctioning cabin, scientists are using a method used by deep space explorers of the mid-20th century.
During the Apollo era, the astronauts did not have a toilet. They only depended on bags to keep themselves cool.
And this method was not always without errors. During the 1969 Apollo 10 mission – in which Thomas Stafford, John Young and Eugene Cernan orbited the moon – Stafford reported to mission control on Day 6 of the mission that debris was floating in the cabin, according to previously classified government documents.
“Quick, give me a napkin,” Stafford was reported to have said a few minutes before Cernan saw more: “Here’s another godfather.”
Astrology hated the practice of collecting excrement.
“Management of waste bags was ineffective and the crew described it as very ‘irritating,'” a 2007 NASA official report later revealed. “The bags didn’t offer odor control in a small capsule and the odor was prominent.”
The Orion team relies on a similar system now officially called the Collapsible Contingency Urinal or CCU. Astronaut Don Pettit, following his mission from home, shared a photo on his social media feed.
The Apollo 10 capsule was not the only one to suffer from toilet problems. The SpaceX Crew Dragon capsule, which realized its first astronaut mission in 2020 and has flown more than a dozen since then, has also had several hiccups with its hygiene system.
During the Crew Dragon flight in 2021, for example, SpaceX discovered that a tube used to pour urine into a storage tank broke, causing a mess to leak under the capsule’s floor. That forced the scientists to rely on underwear – which are basically adult diapers.
NASA’s current director, billionaire tech entrepreneur Jared Isaacman, has also ordered a three-day flight to Crew Dragon in 2022, called Inspiration4. During the flight, he had to solve a toilet problem. The issue, however, did not include stray debris around the cabinet, Isaacman told CNN at the time.
Decades of spacecraft development have informed the system on board Orion that the Artemis II spacecraft uses. NASA installed a similar system on the International Space Station – which orbits several hundred kilometers above Earth – to help test the technology.
Collins Aerospace has a $30 million contract, awarded in 2015, to design and adapt the technology, known as the Universal Waste Management System or UWMS, for Orion.
And the system also builds on decades of toilet technology from the Space Shuttle program. In both systems, the urine is pumped out of the capsule while the solid waste is collected and sent home to the workers.
When it works, an on-site toilet can have its benefits.
“One of my friends even said he’d rather have a bathroom in space than one on Earth,” former NASA astronaut Mike Massimino told CNN.
Massimino isn’t sure, though. “I really miss my World toilet because it is very sensitive to space, and you have to be careful and respect your friends so that you don’t leave a mess,” he said. And keep yourself clean because you don’t want people to get sick.
