Astronauts from NASA’s Artemis II mission spoke candidly on Thursday about a recurring technical issue with the spacecraft’s toilet system during a press conference in Houston.
“We had an issue, and it was an issue for sure,” said mission commander Reid Wiseman.
“The toilet flushed just fine, but then when the liquid went out the bottom of the toilet, it got clogged up in our vent line,” he explained.
“It’s got to be dumped. And for the first two days of the mission, it was fun to watch that thing get dumped,” he added. “That is an interesting thing to see out the window, it’s just like a billion little tiny flecks of ice heading out into deep space.”
According to NASA, the spacecraft’s Universal Waste Management System experienced several operational challenges during the 10-day mission.
The most persistent issue involved the system’s inability to properly vent stored urine into space. Engineers initially suspected ice buildup caused by the extreme cold environment, but attempts to resolve the blockage by exposing the vent nozzle to sunlight and activating onboard heaters did not fully fix the problem.
Because the urine tank has limited capacity, holding fewer than ten uses, the crew had to temporarily switch to collapsible contingency urinals while engineers worked to identify the cause.
Post-mission analysis now suggests the blockage may have been caused by a chemical reaction within the wastewater system, producing debris that clogged the filter rather than a simple freezing issue.
The mission, which launched on April 1, carried its crew further into deep space than any human mission in decades, surpassing the distance achieved by Apollo 13 mission.
