Falcon 9 grounded after upper-stage anomaly; Crew-12 launch window remains on track

SpaceX has grounded its Falcon 9 after the upper stage failed to perform its planned deorbit burn on a Feb. 2 Starlink mission, with SpaceX and the FAA reviewing data to determine root cause before returning to flight. Crew-12 remains on track for an Feb. 11 launch to the ISS, as NASA and SpaceX press to restore the station’s seven-astronaut crew; the upper stage is passivating after venting propellant and is expected to re-enter soon.
