NASA is planning to conduct a cryogenic demonstration test by loading cold liquid hydrogen and liquid oxygen into the Space Launch System (SLS) prior to launch.
NASA is preparing to launch Artemis 1 on September 27. However, WE The space agency will conduct a pre-launch freezing test of Artemis 1 to confirm that the fuel leak has been resolved. Artemis 1 . fuel test moon the rocket will get underway on Wednesday, September 21. “Teams will test adding super-cooling fuel to the #Artemis I rocket on September 21 to confirm the interface fix for this test flight. around the Moon. @NASAArtemis leaders will preview the test during a teleconference on September 19 at 11:30 a.m. ET (15:30 UTC): https://go.nasa.gov/3eQf3fL,” NASA tweeted.
America space The agency had to terminate the mission, due to a liquid hydrogen leak during the refueling of the rocket engine’s tanks. As shared by Space.com, “Technicians replaced the two seals at the quick disconnect point earlier this month, potentially resolving the issue.” and now NASA The Artemis 1 team will load supercooled propellant – liquid hydrogen and liquid oxygen – into the SLS on Launch Pad 39B at NASA’s Kennedy Space Center in Florida to conduct the test.
Earlier, Ars Technica’s Eric Berger explained that the US space agency has a tolerance for small amounts of hydrogen leaks, and anything with a hydrogen concentration above 4% near ‘quick disconnection’ is considered is a flammable hazard.
Follow reportNASA’s Artemis spacecraft with an 8-inch diameter carrying liquid hydrogen into the rocket has “given a persistent leak at the inlet, known as a quick disconnect, resulting in the vehicle”.
Nasa’s Artemis lunar program will use the Space Launch System (SLS) megarocket to send an Orion capsule to explore the Moon’s orbit. It was originally intended to launch Artemis 1 on August 29, but the launch was canceled twice due to technical problems.
