USA TODAY NETWORK Like most SpaceX launches, the liftoff will be livestreamed. But the rocket launch will also be widely visible for many spectators across California and even neighboring Arizona. There's a potential that many in the Southern California area could hear sonic booms. Owned by SpaceX founder Elon Musk, Starlink is a constellation of more than 6,700 satellites that provide internet service to customers around the world. SpaceX, which one week ago called off an attempt to launch a batch of Starlink satellites into orbit from Southern California, is planning to give it another go. The company's famous 230-foot Falcon 9 rocket is scheduled to launch as early as Friday, May 9, from Vandenberg Space Force Base, according to a launch alert from the base. On board the Falcon 9 will be a payload of 26 internet-beaming Starlink satellites for deployment into what's called low-Earth orbit – an altitude that allows for things like satellites to circle Earth fairly quickly. The possible impending launch comes nearly a week after SpaceX, owned by billionaire Elon Musk, called off a previous attempt to get the rocket off the ground to deploy the satellites. Like most SpaceX launches, the liftoff will be livestreamed. But the rocket launch will also be widely visible for many spectators across California, neighboring Arizona and, in some cases, Las Vegas. Here's what to know about the launch, as well as when and where to watch it: What time is the SpaceX rocket launch from California? The launch window opens at 5 p.m. PT (8 p.m. ET) Friday, May 9, and lasts until 7:21 p.m. PT, according to an alert from Vandenberg Space Force Base in Vandenberg, California. If SpaceX opts to scrub the launch, backup opportunities are available beginning at 5 p.m. PT Saturday, May 10. The launch, using a SpaceX Falcon 9 rocket to deliver the Starlink satellites, will take place from Launch Complex 4E from Vandenberg Space Force Base in Santa Barbara County, California. Following the delivery and deployment of the satellites, the Falcon 9 rocket's first stage booster will aim to land on a SpaceX drone ship, nicknamed "Of Course I Still Love You," in the Pacific Ocean. This allows for SpaceX personnel to recover the booster so it can be reused in future spaceflights.
