NASA replaces Artemis 1’s leaky fuel seals

NASA has completed a critical repair of its next-generation Space Launch System (SLS) rocket. On Friday, engineers changed the leaky seal that compelled the company to wash its most up-to-date try to launch Artemis 1. On September third, a becoming on one of many fuel traces to the SLS started leaking hydrogen. Ground crew at Kennedy Space Center tried to troubleshoot the issue 3 times, just for the leak to persist and drive NASA to name off the launch try. On Friday, engineers additionally changed the seal on a 4-inch hydrogen “bleed line” that was liable for a smaller leak throughout an earlier August twenty ninth launch try.

With the brand new gaskets in place, NASA plans to conduct a fueling take a look at to confirm they’re working as meant. The dry run will see engineers try to load the SLS with all 736,000 gallons of liquid hydrogen and oxygen it could want throughout an everyday flight. NASA hopes to efficiently full that take a look at as early as September seventeenth. “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,” the company mentioned.

On Thursday, NASA announced it was concentrating on September twenty third for an additional go at placing Artemis 1 into space, with September twenty seventh as a backup. Whether it will possibly make these dates will rely on subsequent week’s fueling take a look at and a call from the US Space Force. Flight laws require that NASA take a look at the battery of Artemis 1’s flight termination system each 20 days. That’s one thing it will possibly solely do throughout the Kennedy Space Center’s Vehicle Assembly Building. The Space Force beforehand granted the company an extension on the 20-day deadline. NASA has now requested for an additional waiver.
