The toilet aboard SpaceX's Inspiration4 craft malfunctioned during the crew's three-day journey around the Earth last month, causing urine to leak in and outside of the capsule.
William Gerstenmaier, a SpaceX vice president who used to work for NASA, told the New York Times that not only did bodily fluids collect under the floor of the Resilience capsule, but it rained down on spectators watching the craft return to Earth.
'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
