Endeavour of the SpaceX Falcon 9 rocket and Dragon spacecraft at NASA's Kennedy Space Center in Florida was launched on February 27, 2023.
The launch of NASA's SpaceX Crew-6 mission from the Kennedy Space Center's Launch Complex 39A in Florida has been halted. Reportedly, there was an ignition fault with the main engines of the Falcon 9 rocket. Additional information is forthcoming.
NASA said that "all looks good for the Crew-6 launch!" The fuel load for the RP-1 rocket was already complete, and weather conditions were "extremely favorable."
When NASA refers to a space launch or mission as "scrubbed," it implies that the launch or mission has been postponed or canceled.
When a malfunction with the launch vehicle, ground equipment, or weather conditions prevents the mission from going as planned, NASA will "scrub" the launch, essentially postponing it until the issue is resolved or the weather conditions improve.
The decision to postpone a launch is not taken lightly, as it often takes a significant amount of effort and planning to reschedule it. NASA always places an emphasis on the safety of its astronauts and mission personnel, and will only proceed with a launch when all safety requirements have been met.
