This is the second time in as many months that the workhorse vehicle for SpaceX has been grounded. The Federal Aviation Administration is awaiting a report from SpaceX that will include any needed corrective actions.
The crew trained for more than two-and-a-half years to prepare for their spacewalk and an on-orbit Starlink demonstration. Launch is now no earlier than Friday, Aug. 30, weather permitting.
The ignition test of the nine Merlin engines at the base of the rocket came after the four crew members step through a dry dress rehearsal of their launch day activities. The T-0 for ignition happened at 6:38 a.m. EDT (1038 UTC).
The four astronauts, led by businessman Jared Isaacman, will fly onboard SpaceX’s Crew Dragon Resilience. Liftoff is targeting no earlier than Monday, August 26.
