Astronauts returning to Earth from the International Space Station this month will be without a bathroom thanks to an issue with the toilets on SpaceX’s Crew Dragon capsule.
Instead, Shane Kimbrough and Megan McArthur from NASA, French astronaut Thomas Pesquet from the European Space Agency, and Akihiko Hoshide from the Japan Aerospace Exploration Agency must aboard the Endeavor capsule Steve Stich, NASA’s Commercial Crew Program Manager, told reporters on one Press conference on October 29th.
“Our intention is not to use the system on the way back home at all, as we’ve seen on the fluids we’re talking about,” said Stich.
Astronauts often use the undergarments to lighten themselves up in spacesuits for takeoffs, landings, and space walks, Space.com notes.

The toilet on SpaceX’s Inspiration4 spacecraft did not work during the crew’s three-day trip around the earth last month, causing urine to leak into the capsule Shane Kimbrough and Megan McArthur from NASA, French astronaut Thomas Pesquet from the European Space Agency and Akihiko Hoshide of Japan Aerospace Exploration Agency
Engineers first noticed the problems with the SpaceX capsule toilet design after civilians Jared Isaacman, Sian Proctor, Haley Arceneaux and Christopher Sembroski returned from their historic three-day trip around the earth aboard the SpaceX Resilience capsule in September, the first pure tourist trip to Platz.
An alarm went off during reentry, but it wasn’t until the ship was back on Earth that SpaceX crew members discovered that the signal indicated that urine had accumulated under the floor panels after a hose was pulled from the toilet.
They fixed the problem by welding a urine flush hose to the toilet that was on top of the capsule.
The flaw was also discovered on the Endeavor capsule, which flew SpaceX’s Crew 2 mission to the ISS in late April and is currently docked with the orbit laboratory.
The same problem was identified with the Endeavor capsule toilet that Akihiko Hoshide (left) of the Japan Aerospace Exploration Agency, French astronauts Thomas Pesquet of the European Space Agency, and NASAs Shane Kimbrough and Megan McArthur to Earth later this month will bring back. As a result, the toilet is locked and the crew must wear “underwear” to dispose of waste
Astronauts found the same unglued tube and evidence of urine seeping into the floor slabs, but with limited resources they have no way of making the necessary repairs to the Endeavor’s toilet.
Crew 2 astronauts were expected to return to Earth this week, but this could be postponed due to a delay in the start of the Crew 3 mission on October 31 due to weather concerns. (A postponed launch Wednesday was also sunk because of a “minor medical problem” involving a crew member, NASA said.)
SpaceX Vice President William Gerstenmaier, who previously worked for NASA, told the New York Times that the Inspiration4 crew didn’t notice the problem until they returned to Earth.
“When we got the vehicle back, we looked under the floor and found that there was dirt under the floor,” said Gerstenmaier.
According to Isaacman, no body fluids have dissolved in the capsule.
“I want to be 100% clear: there were no problems at all in the cabin about this,” he told CNN.
Urine began to leak from the toilet when a hose came loose and collected under the floor slabs. SpaceX has since fixed the problem by welding a urine flush pipe to the toilet, but the Endeavor is still moored to the ISS and cannot be repaired
The Crew 3 mission that brought a new group of astronauts to the International Space Station on Sunday used a different capsule, the Endurance.
However, its toilet system is the same design as the Resilience capsule, and the Endurance received the same repair to prevent further urine leakage.
SpaceX conducted floor tests to ensure the Endeavor’s design was not compromised by the leakage of urine.
“We’re going to double-check things, we’re going to double-check things, and we have a few more samples to pull out of the chambers and inspect,” Gerstenmaier told CNN. “But we’ll be ready to go and make sure the crew can return safely.”
Stitch said, “The Inspiration4 flight was really a gift for us” to make the crew aware of the problem.
Shortly after Inspiration4, to which Jared Isaacman (left), Sian Proctor (right), Haley Arceneaux (2. It was later discovered that the alarm was due to a broken toilet
In September, Elon Musk said an “upgraded toilet” was one of several upgrades for SpaceX’s next space tourism flight.
In a September 21 tweet, the SpaceX CEO diagonally referred to “challenges” with the toilet on board the modified Crew Dragon module that carried the Inspiration4 crew for a three-day trip into space.
At the time, however, Musk didn’t elaborate on what the toilet was about.
After the Inspiration 4 flight, SpaceX CEO Elon Musk tweeted that improved toilets were definitely needed. He added: “We had some challenges with this flight”
Mission commander, 38-year-old Jared Isaacman, had previously said that the toilet offers a great view of space.
“It’s not a lot of privacy,” Isaacman told Insider in July. “But you have that kind of privacy curtain that cuts through the top of the spacecraft so you can separate yourself from everyone else.”
“And that’s where the glass dome happens to be. So, you know, when people inevitably have to go to the bathroom, they’re going to have a damn good view. ‘
This isn’t the first bathroom mishap ISS astronauts have faced: in 2019, the crew rushed to fix plumbing after a bulging pipe was severed from the bathroom sink, dousing more than two at the unsuspecting scientists Liters of water.
The very down to earth problem arose in the orbit lab when the astronauts tried to install an enclosure around the onboard toilet for added privacy.
This unfortunate debacle forced scientists to crawl around with towels to absorb the spherical water pearls that form in weightlessness.
They were gathered in the bathroom to install the extra cubicle when they disconnected a Quick Disconnect (QD) for the drinking water bus used by the astronauts for teeth brushing, bathing, and other hygiene routines.
About 2.5 gallons leaked before the bus was isolated by MCC-H flight controllers, as described in a NASA blog post.
“The crew worked quickly to reconnect the leaking QD and soak up the water with towels.”
While spherical balls form in a microgravity environment, it is unclear whether the water exited at high pressure at low pressure.
“If it were a slow leak, it would have formed into a large, undulating lump that would have drifted or crawled along the wall with surface tension,” Tom Jones, a former NASA astronaut, told The Atlantic.
“If it was under a higher pressure and it came out at high speed, it would spray and send droplets flying through the cabin.”
In October 2020, North Grumman launched its Cygnus capsule with a highly acclaimed $ 23 million toilet to the ISS.
The Universal Waste Management System (UWMS) zero gravity toilet was developed to better suit the female anatomy than current space toilets.
HOW DO ASTRONAUTS GO IN THE BATHROOM?
There is a toilet with several attachments on board the ISS.
Since there is no gravity in space, liquids do not flow but collect in floating spheres.
To address this problem, there are tubes that are used that create pressure to suck the fluid out of the body.
Every astronaut has his own personal bond.
When a toilet is not available or the astronaut is on a space walk, the astronauts use MAGs (maximum absorbency), diapers that soak up all waste.
They are effective for short missions but have been known to leak occasionally.
Nasa has set itself the goal of developing a suit that enables the long-term use of spacesuits and the complete independent disposal of human waste.
There was no toilet on the lunar missions and the all-male crew had condom catheters that were attached to the penis and the fluid was directed into a pouch outside the suit.
According to an interview with astronaut Rusty Schweickart in 1976, the condom catheters came in three sizes: small, medium and large.
Despite the practical advantages of the right size, astronauts often ordered the large ones, which resulted in leakage of urine in the suit.
To combat this, NASA renamed the sizes large, gigantic and huge to appease the male ego.
An effective female equivalent has yet to be developed, which NASA would like to change for the Orion missions.
