>NASA is loading liquid hydrogen aboard its Space Launch System moon rocket at the Kennedy Space Center on Thursday for an unpublicized but crucial test of the repairs made to a leaky umbilical that derailed a countdown rehearsal on Feb. 2.
The operation to load liquid hydrogen into the huge fuel tank on the rocket’s core stage was thought to be already underway at launch complex 39B on Thursday morning. The test will determine if new seals installed in the launch pad umbilical are working.
“As part of our work to assess the repair we made in the area where we saw elevated hydrogen gas concentrations during the previous wet dress rehearsal, engineers are testing the new seals by running some liquid hydrogen across the interface and partially filling the core stage liquid hydrogen tank. The data will inform the timeline for our next wet dress rehearsal,” a NASA spokesperson said about the previously unannounced test.
