Toilet on SpaceX's Inspiration4 craft malfunctioned and URINE collected under the capsule's floor

The toilet aboard SpaceX‘s Inspiration4 craft malfunctioned during the crew’s three-day journey around the Earth last month, causing urine to leak inside capsule.

William Gerstenmaier, a SpaceX vice president who used to work for NASA, told the New York Times that bodily fluids collected under the floor of the Resilience  capsule.

‘We didn’t really even notice it, the crew didn’t even notice it, until we got back,’ Gerstenmaier said.

‘When we got the vehicle back, we looked under the floor and saw the fact that there was contamination underneath the floor of Inspiration4.’

Urine began leaking from the toilet when a tube came unplug and pooled beneath the floor panels. 

SpaceX has since fixed the issue by welding on a urine-flushing tube to the toilet and NASA is expected to sign off on the new design on Friday.

 The Elon Musk-led company is using the same toilet design for Sunday’s Crew-3 mission that is taking a new batch of astronauts to the International Space Station.

While the Crew-3 mission will be using a different capsule — recently named ‘Endurance’ — its toilet system shares a design with that of the Resilience capsule.   

Shortly after Inspiration4, which included Jared Isaacman, Sian Proctor, Haley Arceneaux and Christopher Sembroski, arrived back on Earth, reports surfaced that an alarm went off while the four were in orbit, CNN reports. 

The SpaceX Crew Dragon spacecraft’s systems warned the crew of a ‘significant’ issue, Isaacman said.

The issue ended up being a malfunctioning toilet, but it was not identified until after the crew’s return.

The flaw in the original toilet plumbing may also affect the Endeavour capsule which flew SpaceX’s Crew-2 mission to the ISS back in late April this year.   

The Endeavour capsule is presently docked with the orbiting laboratory and scheduled to depart on November 4.

It is likely that the capsule will require upgrading on its return to Earth. 

The toilet design seems to be fixed, allowing the Endurance capsule to launch on October 31.

This will be SpaceX’s fourth launch of NASA astronauts and its fifth passenger flight overall.

The upcoming mission, dubbed Crew-3, will transport NASA’s Raja Chari (the mission commander), Tom Mashburn, Kayla Barron and Matthias Maurer of the European Space Agency to the ISS for a six month stay.
