The NASA Teams Replace Seals on Artemis, After first disconnecting the ground and rocket-side plates on the interface, called a quick disconnect, for the liquid hydrogen fuel feed line, teams have now replaced the seals on the Space Launch System (SLS) rocket’s core stage associated with the liquid hydrogen leak detected during the Artemis I launch attempt on September 3.
After first disconnecting the ground and rocket-side plates on the interface, called a quick disconnect, for the liquid hydrogen fuel feed line, NASA Teams Replace Seals on Artemis, teams have now replaced the seals on the Space Launch System (SLS) rocket’s core stage associated with the liquid hydrogen leak detected during the Artemis I launch attempt on September 3. Both the 8″ line used to fill and drain liquid hydrogen from the core stage and the 4″ bleed line used to redirect some of the propellant during tanking operations were removed and replaced this week.
During the operation, teams will practice loading liquid hydrogen and liquid oxygen in the rocket’s core stage and interim cryogenic propulsion stage. They will work at getting to a stable replenish state for both propellants. Teams will confirm the leak has been repaired. NASA Teams Replace Seals on Artemis, They will also perform the kick-start bleed test and a pre-pressurization test to validate that the ground and flight hardware and software systems can perform the necessary functions required to thermally condition the engines for flight. Teams will review the test results and develop strategies for the next launch opportunity after analyzing the data.
