After standing down on the NASA Artemis I launch attempt on Saturday, September 3 due to a hydrogen leak, engineering teams have decided to replace a seal while at the launch pad. The seal is on an interface, called the quick disconnect, between the liquid hydrogen fuel feed line on the mobile launc
Performing the work at the launch pad requires technicians to set up an enclosure around the work area to protect the hardware from the weather and other environmental conditions. However, it enables engineers to test the repair under cryogenic, or supercold, conditions. Another advantage to performing the work at the pad is that it allows teams to gather as much data as possible to understand the cause of the issue.
NASA would need to roll the rocket and spacecraft back to the VAB before the next launch attempt to reset the system’s batteries in order to meet the current requirement by the Eastern Range for the certification on the flight termination system. In addition, teams will also check plate coverings on other umbilical interfaces to ensure there are no leaks present at those locations. There are seven main umbilical lines, and each line may have multiple connection points.
