Engineers detected a liquid hydrogen leak in a quick disconnect cavity and have stopped flowing the propellant to the core stage while they troubleshoot. Launch controllers are attempting to warm up the quick disconnect to attempt to reseat it to get a tight seal. Liquid oxygen flow is continuing.
Engineers have started loading super cold liquid hydrogen into the Space Launch System rocket’s core stage and the fast fill phase for the core stage liquid oxygen tank also has started. The countdown clock, which was in a 2.5 hour built in hold, has resumed.
Engineers have started the slow fill phase of loading super cold liquid oxygen into the Space Launch System rocket’s core stage.
Artemis Launch Director Charlie Blackwell-Thompson has given the “go” to officially begin loading propellants into the Space Launch System rocket. Tanking begins with chilldown of the core stage liquid oxygen transfer line. NASA TV coverage will begin at 5:45 a.m. http://www.nasa.gov/live.
The Artemis I Mission Management Team has given the “go” to proceed toward tanking operations. Weather conditions remain 60% favorable at the beginning of the two-hour launch window which opens at 2:17 p.m. EDT Sept. 3, with conditions improving to 80% favorable toward the later part of the window.
