SpaceX Starship Launch Delayed Again After Second Last-Second Abort in Four Days
SpaceX Starship launch experienced a second last-second engine shutdown in four days, forcing postponement of Flight 13.
SpaceX has postponed its Starship megarocket launch for the second time in four days after engines shut down during final countdown procedures. The aerospace company now plans to reattempt Flight 13 on Thursday afternoon, following inspection and replacement of two Raptor engines. A separate Falcon 9 rocket also experienced a last-second abort at Vandenberg Space Force Base in California, though engineers believe the two incidents are unrelated.

The Starship Setback
Starship's Flight 13 test was aborted as the Super Heavy booster's engines began ignition sequence. The shutdown triggered a review of the vehicle's 33 Raptor engines—the next-generation powerplants that distinguish Starship from conventional rockets. SpaceX engineers identified two units requiring replacement, according to mission updates.
The 13th test flight carries significant importance in SpaceX's development roadmap. Starship represents the company's most ambitious project: a fully reusable launch system combining unprecedented payload capacity with rapid reusability. The vehicle stands as the largest and most powerful rocket ever constructed.
A Broader Launch Pause
The same morning, SpaceX attempted to launch a Falcon 9 rocket carrying 24 Starlink internet satellites from Vandenberg. That mission also aborted at engine ignition. Despite this delay, the Falcon 9 boasts an exceptional reliability record, having completed 84 successful launches this year without failure.
The two vehicles employ fundamentally different propulsion systems. Falcon 9's first stage uses nine Merlin 1D engines, whereas Starship's booster relies on the advanced Raptor design. Engineers stated that the two aborts likely share no common cause beyond unfortunate timing.
The Falcon 9 Starlink mission is scheduled for Tuesday morning from California, operating within a four-hour launch window beginning at 10 a.m. Eastern Daylight Time. Starship's rescheduled attempt follows on Thursday.
