Fueling was scheduled to commence just after midnight on August 29, 2022, but was delayed an hour due to offshore storms, only beginning at 1:13 am EDT. Before the planned launch at 8:33 am, Engine 3 of the rocket's four engines was observed to be above the maximum allowable temperature limit for launch. Other technical difficulties involved an eleven-minute communications delay between the spacecraft and ground control, a fuel leak, and a crack on the insulating foam of the connection joints between the liquid hydrogen and liquid oxygen tanks. NASA scrubbed the launch after an unplanned hold and the two-hour launch window expired. An investigation revealed that a sensor not used to determine launch readiness was faulty and displayed an erroneously high temperature for Engine 3.
