However the bathroom predicaments haven’t stopped there. One other Crew Dragon capsule that docked to the area station in April with 4 astronauts aboard has the identical plumbing system because the Inspiration4 capsule. SpaceX engineers feared the identical “contamination” might need occurred on that spacecraft.
The engineers’ suspicions had been appropriate.
NASA astronauts dwelling on the station snaked a borescope machine — a cable with a tiny digicam on the finish — beneath the capsule’s ground and found traces of urine in locations it shouldn’t be, Mr. Gerstenmaier mentioned. “Sure, there was some indication of some contamination below the ground,” he mentioned.
That raised new issues. In area, urine is combined with a probably corrosive compound, oxone, to eradicate ammonia. Might the oxone-laced urine, sitting within the capsule for months, have corroded any essential {hardware}?
To reply this query, Mr. Gersteinmaier mentioned, SpaceX engineers on Earth gathered aluminum components much like these on the spacecraft and created a sampling of urine combined with oxone. They soaked the components and positioned them inside a chamber that mimicked the humidity circumstances aboard the area station for “an prolonged time frame,” Mr. Gerstenmaier mentioned.
The wayward waste contained in the Inspiration4 capsule was extra voluminous than the contamination discovered on the capsule hooked up to the area station, he mentioned, as a result of the passengers used the capsule for 3 days whereas astronauts launching to the area station are sometimes in orbit for about 24 hours. The outcomes of the bottom exams seem constructive thus far, he mentioned: “Fortunately, or, on objective, we selected an aluminum alloy that may be very insensitive to corrosion.”
That capsule is scheduled to undock from the station in November and return house with the 4 astronauts it delivered in April. The bottom exams with the oxone and urine are persevering with.
“We obtained a pair extra samples we’ll pull out of the chamber,” Mr. Gerstenmaier mentioned. He didn’t say who offered the samples.
