Index – Tech-Science – Decreased space defecation

Published on


During SpaceX’s first civilian crude space flight (Inspiration 4), amateur astronauts encountered a problem with a toilet wrapped in a dragon capsule during a three – day orbit. At the time, the company did not specify what the problem was, and since a tube was loose, the urine and feces entering the toilet could not be properly removed with a suction fan, so the final product literally went to it.

SpaceX will launch its fourth manned mission on Sunday, October 31 (Crew-3) On behalf of NASA, the space agency and Elon Musk need to ensure that the issue surrounding the Dragon Toilet does not disrupt the launch from the Kennedy Space Center or the path and connection to the International Space Station. Similarly, the dragon, currently parked on the ISS, needs to be checked to make sure there are no problems for astronauts returning from the station after six months.

Former NASA employee William Gerstenmeier is the current Vice President of SpaceX Said, The used part of the joint was completely replaced with a welded tank and the toilet problem was solved. Inspiraton4 loosened during flight. The built-in restroom of Crew Dragon capsules carries human feces through a tube into a container, where it is stored. During the Inspiration 4 flight, the glued fit of the pipe was released, and as a result, the astronauts came out into the suction system operated by the toilet and into the vicinity of the tank. To prevent this from happening, the previously glued part of the pipeline was replaced with welded; NASA is currently reviewing the solutions.

Fortunately, the Inspiration 4 flight did not cause any problems with the error, however, upon returning, SpaceX found dirt from the toilet under several cover panels that should not have been there.

Gerstenmeyer further explained that in the Dragon capsule, which is currently parked on the ISS, very little urine flows under the panels. This is because while the Inspiration 4 spent three days in space orbiting the Earth, the Crew 2 flew only one day between launch and docking at the International Space Station, so the crew used less of their space cover. Regardless, SpaceX and NASA are testing the Crew-2 return capsule, the results of which are expected by Friday. Steve Stitch, manager of NASA’s Commercial Crew Program, which controls commercial space travel, said they were looking for small signs such as low pressure and temperature changes that indicate a problem with urine leaking from the toilet. The space station staff also inspected the capsule’s toilet with a boroscope, and ground staff examined the devastating effect of the defecation on the aluminum in the capsule docked at the space station.

Before leaving, NASA had previously told Crew-2 to go to the ISS toilet and try to stop him on the way.

After the launch of Inspiraton4, SpaceX reinforced the crew-3 with not only cloth but also parachutes used to return, following the discovery of unexpected clothing in the canopy capsules of the previous mission. NASA has already checked this and found that everything is OK in the repair.

Crew-3 Commander Raja Chari, pilot Tom Marshburn, mission specialist Kyla Barron, and all NASA astronauts. Matthias Maurer, an astronaut from the European Space Agency (ESA), is the fourth session of the previously unseen Dragon capsule. The astronauts named their dragon Endurance. The astronauts are already making final preparations in Florida, and if everything goes according to plan and the Sunday launch is successful, they will arrive at the space station on November 1, where they will be on duty until April 2022. It is planned that the next Dragon capsule will arrive with their switch.

Shane Kimbro (NASA), Megan McArthur (NASA), Akihiko Hosside (Jaxa) and Thomas Pesquet (ESA) are on the ISS on a six-month mission from April this year. The Crew-2 He will return to Earth on November 4 or 5 in the dragon capsule Endeavor.

Although the Dragon capsule used by the Crew-3 is brand new, the mission will be launched using an already used Falcon 9 launch vehicle. The spacecraft and rocket have already been assembled, and the launch of the first phase of the experiment carried out 39A, the launch site of the Kennedy Space Center.
