SpaceX pauses launches after de-orbit of Falcon 9’s second stage misfires
SpaceX today announced that, after its Falcon 9 rocket had successfully placed two astronauts in orbit in its Freedom capsule, the engine burn designed to de-orbit the rocket’s upper stage in a safe zone in the ocean misfired, and for this reason the company was scrubbing a planned launch today until the root cause was found.
After today’s successful launch of Crew-9, Falcon 9’s second stage was disposed in the ocean as planned, but experienced an off-nominal deorbit burn. As a result, the second stage safely landed in the ocean, but outside of the targeted area.
We will resume launching after we better understand root cause
The company provided no further details on exactly what happened. We know the engine fired, and the stage was successfully de-orbited safely over the ocean, but we do not know how far outside its target zone. Nor do we know the extent of the “off-nominal deorbit burn.”
At present today’s scrubbed launch, placing three satellites of Starlink’s competitor OneWeb into orbit, is scheduled for tomorrow, but that is likely a contigency scheduling. SpaceX’s launch teams have gotten very good at rescheduling launches day-to-day, so that as soon as it gets the go-ahead it can go ahead.
