Ground system issue scrubs first launch of SpaceX's Starship V3 rocket

SpaceX got within 40 seconds of launching the first flight of a taller, more powerful version of its Starship rocket Thursday, but a pesky problem with the launch tower kept the vehicle bound to Earth for at least one more day. Clouds and rain showers cleared the area around SpaceX's launch site in South Texas, leaving mostly sunny skies over the Starship launch pad Thursday afternoon. SpaceX pushed back the launch time by one hour, but the countdown appeared to proceed smoothly once propellants began loading into the rocket. That was true, at least, until the countdown clock paused 40 seconds before liftoff. The launch team repeatedly attempted to resume the countdown, only for the computer controlling the launch sequence to stop the clock again. There were five holds in all before SpaceX called off the launch attempt. Read full article Comments

SpaceX got within 40 seconds of launching the first flight of a taller, more powerful version of its Starship rocket Thursday, but a pesky problem with the launch tower kept the vehicle bound to Earth for at least one more day.

Clouds and rain showers cleared the area around SpaceX's launch site in South Texas, leaving mostly sunny skies over the Starship launch pad Thursday afternoon. SpaceX pushed back the launch time by one hour, but the countdown appeared to proceed smoothly once propellants began loading into the rocket.

Engineers could make another attempt to launch Starship as soon as Friday evening.

β€œIt is sounding like we are not going to be able to clear this issue in time today, so we are going to be standing down from a launch,” said Dan Huot, a SpaceX official hosting the company’s live broadcast Thursday. β€œWe got the vehicle totally loaded. We hit a couple of different holds as we worked through that count.”

Elon Musk, SpaceX’s founder and CEO, attributed the scrub to a hydraulic pin that failed to retract on an umbilical arm connecting the launch tower to the rocket. β€œIf that can be fixed tonight, there will be another launch attempt tomorrow,” Musk wrote on X. The 90-minute launch window Friday would open at 5:30 pm CDT (22:30 UTC).
