A Falcon 9 rocket and its 50 satellites will wait until Thursday night before trying to depart from Vandenberg Space Force Base.
The two-stage rocket’s liftoff will target 11:47 p.m. from Space Launch Complex-4 on South Base.
“The additional time allows teams to complete pre-launch checkouts and for weather conditions to improve,” according to to an update posted Tuesday afternoon to the Space Exploration Technologies Twitter account.
The team initially planned for a Monday night launch and then announced it would not occur before Tuesday night before revealing the latest delay.
Following the launch, the first-stage booster will return to Vandenberg, likely accompanied by sonic booms that could be audible in Santa Barbara, Ventura and San Luis Obispo counties.
The mission known as Transporter-7 involves a dedicated rideshare payload including CubeSats, MicroSats, hosted payloads, and orbital transfer vehicles carrying spacecraft to be deployed at a later time, according to SpaceX.
Among customers for this mission is Santa Barbara-based Umbra, manufacturer of synthetic aperture radar satellites capable of delivering images despite clouds, smoke and total darkness with industry-leading resolution.
A batch of cremated remains of people and a few cats also will head to space on the newest memorial spaceflight for Celestis Inc.
Deployment of the Transporter-7 payloads will begin approximately an hour after launch and end more than 2 1/2 hours later.
A live webcast of this mission will begin about 10 minutes prior to liftoff at SpaceX and on the firm’s channel on YouTube.
