When launching rockets into space, astronauts must prepare for a variety of unforeseen problems, from fuel leaks to sensor malfunctions.
The last problem they expected at this critical moment was a malfunctioning toilet – but NASA astronauts were forced to hold their bladders for the first six hours aboard the Orion spacecraft.
At least one of the four astronauts on the Artemis 2 moon mission had to relieve himself in a NASA-approved bag because a fan in the toilet control system failed shortly after takeoff, a NASA executive said.
The 10-day mission, launched on Wednesday, plans to take astronauts to the far side of the moon and potentially farther than humans have ever gone into space before.
Although they did not land, the test flight will evaluate life support equipment and pave the way for a lunar landing in 2028, after which the United States will establish a base on the lunar surface.
On Wednesday night, mission specialist Christina Koch played the role of a space plumber, removing parts from the toilet and performing a series of steps sent via radio from NASA’s Space Center in Houston, including turning it off and back on.
After hours of tinkering, the astronauts were advised to let the system warm up to operating speed “before donating fluids.” They received the good news that they can use the toilet four hours before bed.
“You can use the bathroom all night,” mission control said, much to the relief of everyone on board.
To solve the problem of using the toilet in zero gravity, NASA has spent more than £17.4 million building a “Universal Waste Management System”.
Despite the problems faced by the system, the specialized seats to which the astronauts were strapped, which sucked feces into sealed containers, remained intact.

Waste disposal created a problem on previous Apollo missions when the spacecraft had no toilets, forcing astronauts to relieve themselves in adhesive-sealed plastic bags attached to their bodies.
According to flight logs, during the 1969 Apollo 10 moon landing mission, commander Thomas Stafford said: “Give me a napkin. There’s a piece of shit floating in the air.”
The toilet on Orion is technically called a “sanitation module” and is similar in size to those on passenger aircraft.
To use it, astronauts use foot restraints to hold it in place while using airflow to stir solid waste into a storage container.
For urine, each astronaut is equipped with his or her own personal funnel, complete with a fan that draws the liquid into the tank.
The space on the spacecraft is tight, about the size of two SUVs, and mission expert Jeremy Hansen described the toilet as “a place we can go on a mission where we can feel like we’re alone for a moment.”
As astronauts embark on a 10-day mission to return humans to the moon for the first time since 1972, toilet issues aren’t the only problem they face.
The crew seemed to have trouble finding pajamas, with Commander Reed Wiseman asking about the location of the “comfort suits” as they prepared for a nap.
Not long ago, he requested technical support for a non-working PCD (Personal Computing Device), including an Outlook email account issue.
In addition to these hiccups, the mission was forced to contend with a number of technical issues as it entered orbit at 17,000 mph (22 times the speed of sound).
A valve connecting the two sets of tanks had to be reset after being found closed when it should have been open – most likely due to violence during the launch.

Engineers also encountered a similar minor electronic issue on the Artemis I launch in 2022, when a component briefly tripped due to radiation, underscoring the challenges of a crewed test flight.
In the hours before launch, a series of technical glitches threatened to derail the plan as problems were discovered in the batteries of both the flight termination system, which would destroy the rocket if it strayed off course, and the launch abort system, which pulls the capsule away from danger if something went wrong.
An official later said that thanks to engineers’ “quick action” the problem was resolved and the final liftoff was delayed by only 10 minutes.
The giant 322-foot-tall Space Launch System rocket took off Wednesday at 11:35 p.m. (6:35 p.m. ET).
The spacecraft will remain close to Earth until Friday, with astronauts inspecting the capsule in orbit before firing up its main engines to propel it toward the moon.
The capsule is already more than 40,000 miles from Earth and is about 220,000 miles away from reaching the moon.
After the launch, NASA Administrator Jared Isaacman said America’s “next leap” was underway and vowed “America will never give up on the moon again.”
US President Donald Trump said the United States is “winning in space, on Earth and everywhere in between – economically, militarily and now beyond the stars.”
