The four astronauts of the Artemis II mission, the first manned lunar expedition in more than 50 years, had some technical setbacks after liftoff on Wednesday from Cape Canaveral, Florida (United States).
The most striking of all: the Orion capsule’s toilet stopped working just hours after launch.
A stuck fan and a solution from Houston
The crew reported a flashing warning light shortly after takeoff, prior to a scheduled engine maneuver. Then came the problem of the bathroom.
“We are informed that the fan in the bathroom is stuck. Now teams on Earth are developing instructions on how to access the fan and clear that area.” to get the bathroom working again,” said NASA spokesman Gary Jordan.
Meanwhile, the astronauts could only partially use the toilet: “The collection of feces from the toilet, that specific capacity, can still be used with the waste management system on board the Orion,” Jordan explained. The urinary function, on the other hand, was out of order.
As reported Home.com, at least one crew member used an emergency bag before the repair. It is an emergency folding urinal that was full and had to be emptied overboard, crew member Christina Koch reported.
With the attendant of mission adjustment, Artemis II astronaut and self-described ‘web page plumber’ Christina Koch mounted the Orion spacecraft’s malfunctioning lavatory.

The bathroom is available again
Working in close coordination with the adjustment center in Houston, the crew managed to resolve the problem, details a brief NASA report.
Amy Dill, in charge of communication with the astronauts, gave Koch the good news over the radio: “I am pleased to report that the bathroom is now ready for use.”
The final instructions left no room for doubt: “We recommend letting the system reach its operating speed before urinating, and then letting it run for a while longer after urinating.”
The most advanced space toilet in history
The toilet on board the Orion capsule is not a minor detail. It is the first time that a toilet has been permanently installed on a spacecraft beyond Earth orbit.
On the Apollo missions, more than half a century ago, astronauts used plastic bags for solid waste and they poured urine directly into space, remember Home.com.
The new Universal Waste Management System is designed for men and women, and has a small door that guarantees privacy.
Technically, it is called a “hygiene module” and has approximately the same space as a commercial airplane bathroom, according to Lockheed Martin, the company that built the ship for NASA.
Go to the bathroom with ear protection
However, it has an uncomfortable peculiarity: it is very noisy. Astronaut Koch recently warned in a video National Geographic that the crew must protect their hearing when using the bathroom.
This “is the only place we can go during our mission where we can feel alone for a moment,” added Jeremy Hansen, crew member and member of the Canadian Space Agency, in a presentation video.
How does waste behave in space?
To use the toilet, astronauts hold onto footholds. The system extracts solid waste through a flow of air towards a collection device, while each crew member has their own inner most funnel with a fan to suck the urine into a tank.
Health problems in space have history. In 2021, four astronauts returned to Earth from the International Space Station (ISS) wearing a type of diaper because the toilet in their Crew Dragon capsule did not work.
Other technical problems on takeoff
The toilet wasn’t the only problem. Just after taking off, the mission suffered a communication failure: The crew could hear the adjustment center, but the inner most on the ground did not receive the astronauts’ voices.
“Communications with the crew have been restored. We are actively working on the issue and will keep you informed.”“said NASA Administrator Jared Isaacman at a press conference.
Despite the inconveniences and delays, the mission continues. Artemis II carries Canadian Hansen and Americans Koch, Victor Glover and Reid Wiseman, on a 10-day trip around the Moon, the first with a human crew in more than half a century.
