SpaceX scrubbed the first launch of its third-generation Starship rocket system from its Starbase headquarters in Texas on Thursday, delaying a high-stakes test of Elon Musk's upgraded vehicle as the company moves toward a potentially record-setting public listing.

Launch Scrubbed Seconds Before Liftoff The company called off the launch seconds before liftoff after multiple countdown pauses tied to fuel temperature and pressure readings.

Musk said on X that a hydraulic pin on one of the launch tower's giant mechanical arms "did not retract" as designed.

"If that can be fixed tonight, there will be another launch attempt tomorrow," he said.

The hydraulic pin holding the tower arm in place did not retract.
