NASA’s New Project: Artemis


On Friday, September 9, engineers working on the enormous Artemis 1 Space Launch System (SLS) megarocket’s tail completed the seal replacements, according to a NASA report.

The 8-inch line heading into the core stage of the 32-story SLS rocket’s hydrogen fuel leak is the target of the repair effort. Because of the leak, NASA had to cancel the launch of Artemis 1, the first unmanned test mission of the Artemis program, which intends to send astronauts back to the moon, on September 3. “This demonstration will allow engineers to check the new seals under cryogenic, or supercold, conditions as expected on launch day and before proceeding to the next launch attempt,” On Friday, NASA posted an update.

“Teams will confirm the leak has been repaired and also perform the kick-start bleed test and a pre-pressurization test, which will validate the ground and flight hardware and software systems can perform the necessary functions required to thermally condition the engines for flight,” NASA officials wrote in the update. “Following the test, teams will evaluate the data along with plans for the next launch opportunity. ”

NASA will be able to conduct a “kick-start bleed test” on the four main engines of the SLS rocket during the forthcoming fuelling test. In order to get the engines ready for their super-chilled propellant, that test is meant to chill them down to minus 420 degrees Fahrenheit (minus 251 degrees Celsius). During the initial two attempts to launch Artemis 1, the CIA was unable to conduct that test.
