NASA had to test the addition of supercooled fuel to Space Launch System (SLS) tanks to validate repairs made after a second launch attempt was canceled in late August. The ground crew at Kennedy Space Center noticed a persistent hydrogen leak in one of the SLS fuel lines and tried to fix it three times during the day. In the end, the team failed and decided to postpone the mission.
While the engineers encountered another hydrogen leak during the most recent fuel test, this time the troubleshooting efforts paid off and the leak was found to be “within acceptable limits”.
Artemis 1 launch director Charlie Blackwell-Thompson said the testing went “very well” and the team was able to complete all the tasks assigned to it. NASA will now evaluate data from the test before deciding whether another mission launch can be scheduled on the scheduled date of September 27.
