Artemis mission has suffered months of delays
The Artemis mission has suffered a series of setbacks since an original launch date in late August that was expected to feature Vice President Kamala Harris in attendance among about 100,000 spectators.
NASA called off that initial takeoff, set for Aug. 29, after a defective sensor prevented one of the rocket's engines from cooling down to a temperature required before ignition.
Days later, a second launch attempt on Sept. 3 was scrubbed after the space agency identified a liquid hydrogen leak.
A third planned launch attempt, on Sept. 27, faced postponement due to Hurricane Ian. The rocket was moved off the launchpad to protect it, as Ian wrought destruction along its path northward from Florida to the Carolinas.
