A Firefly Aerospace Alpha rocket’s liftoff has been scrubbed due to weather, and the next attempt at Vandenberg Space Force Base won’t occur until Friday.

Liftoff will aim for a window extending from 9:18 a.m. to 9:39 a.m. Friday, Firefly confirmed Wednesday afternoon.

“Today’s launch attempt of our Alpha rocket has been scrubbed due to weather conditions. Firefly will work with the range to determine our next launch opportunity – stay tuned for more details,” Firefly representatives said approximately two hours before the planned liftoff.

Wednesday’s attempt coincided with the stormy weather expected to soak the Central Coast through Friday.

Despite a forecast calling for just a 30% chance of favorable conditions, the team began counting toward liftoff Wednesday morning before halting efforts.

Earlier this week, Firefly officials said they had backup opportunities through Friday morning if the launch didn’t take place as planned Wednesday.

“The rocket and payload remain healthy – we’re just waiting on Mother Nature,” Firefly said Wednesday afternoon while confirming they skip Thursday and try again Friday.

The rocket will carry a Lockheed Martin Corp. spacecraft while also demonstrating responsive space operations, or the ability to quickly conduct a mission to place a payload in space. 

A livestream of the countdown and liftoff will start 1 hour before the planned liftoff, according to Firefly.
