SpaceX has said liftoff would aim for 1:48 a.m. from Space Launch Complex-4 on the South Base, bypassing an earlier opportunity.
If needed, four backup opportunities are available ending at 4:04 a.m. Monday.
However, if the rocket doesn’t get off the ground early Monday morning, the team also has reserved time for a second attempt with six backup opportunities starting at 11:59 p.m. Monday and ending at 3:42 a.m. Tuesday.
The two-stage rocket will carry another 21 Starlink spacecraft from the system’s second-generation satellites.
Deployment of the satellites from the rocket will take place approximately one hour after liftoff, according to SpaceX.
It’s the sixth flight for the first-stage booster supporting this launch, which previously carried a Space Development Agency mission and four other batches of Starlink satellites from Vandenberg.
After doing its job, the first-stage booster will land on a drone ship, dubbed Of Course I Still Love You, which will be stationed in the Pacific Ocean.
SpaceX has launched more than 5,000 satellites for Starlink, designed and manufactured by the firm to provide high-speed Internet service to remote and rural locations where access remains unreliable or unavailable.
This month marks two years since Vandenberg’s first mission to deliver Starlink satellites into orbit, with 24 launches taking place since Sept. 13, 2021.
Most of the firm’s Starlink deliveries have occurred from Florida.
“Starlink is available on all seven continents, in over 60 countries and many more markets, connecting 2M+ active customers and counting with high-speed internet,” Starlink representatives said on social media.
A live webcast of the mission will begin on the firm’s account on the site formerly known at Twitter, X @SpaceX, about five minutes before liftoff.
