As engineers increased the pressure on the flow of liquid hydrogen into the core stage, a leak reoccurred. Engineers will attempt to reseat the seal in the quick disconnect cavity where the leak has been detected. This time they will stop flowing liquid hydrogen to the tank, close the valve used to fill and drain …
Launch controllers have resumed flow of liquid hydrogen to the core stage after warming up a quick disconnect in the engine section where a hydrogen leak was detected in the cavity between the ground and flight side plates of the quick disconnect. Teams warmed up the quick disconnect to attempt to reseat it and set …
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. Artemis I launch director Charlie Blackwell-Thompson …
Following the Artemis I pre-launch briefing, meteorologists with the U.S. Space Force Space Launch Delta 45 predict a 60% chance of favorable weather conditions at the beginning of the two-hour launch window that opens at 2:17 p.m. EDT Sept 3, increasing to an 80% chance of favorable weather conditions toward the later part of the …
The Artemis I mission management team met this afternoon to review the status of the operations and have given a “go” for a Sept. 3 launch attempt of the Space Launch System rocket and Orion spacecraft. Since the previous launch attempt on Monday, Aug. 29, teams have updated procedures, practiced operations and refined timelines. Over …
Meteorologists with the U.S. Space Force Space Launch Delta 45 predict a 60% chance of favorable weather conditions for an Artemis I launch attempt during a two-hour window that opens at 2:17 p.m. EDT Saturday, Sept. 3. While rain showers are expected in the area, they are predicted to be sporadic during the launch window. …
