A Falcon 9 rocket launch and landing at Vandenberg Space Force Base has been delayed a second day in a row.

“To allow more time to perform ground system checkouts, standing down from today’s launch of the COSMO-SkyMed Second Generation mission,” SpaceX representatives said on social media Sunday afternoon. “A new target launch date will be shared once confirmed.”

After initially aiming for Saturday departure, SpaceX officials scrubbed the attempt saying crews needed time to “troubleshoot a ground systems issue.”

In addition to pinpointing the problem as a glitch involving ground support equipment, SpaceX said both the rocket and its payload remained healthy.

SpaceX did not confirm a new date for the mission, but the Federal Aviation Administration has released notices to pilots for a possible Vandenberg launch Tuesday evening with Wednesday evening being a backup opportunity.

However, the next launch attempt would depend on SpaceX finding and fixing the problem involving the ground equipment.

Following the launch, the first-stage booster, making its 21st flight, is scheduled to return to land at Vandenberg approximately eight minutes after liftoff. 

That means residents in Santa Barbara, Ventura and San Luis Obispo counties may hear sonic booms. 

The delay also means the team may encounter the next round of rain expected to arrive Wednesday.

The mission, carrying an Italian Earth-imaging satellite, has been in line to be the final SpaceX launch of 2025 and the final liftoff of the year from Vandenberg.
