USA TODAY NETWORK SpaceX's famous two-stage Falcon 9 rocket will get off the ground to deliver a batch of Starlink satellites into orbit. The rocket launch will also be widely visible for many spectators across both California and even neighboring Arizona. Update: The launch is now scheduled for 1:36 p.m. PT (4:36 p.m. ET) Friday, May 23, the Vandenberg Space Force Base said in an updated launch alert. If needed, additional launch opportunities are also available on Saturday, May 24 starting at 1:14 p.m. PT. A SpaceX satellite launch in California could provide quite a show for spectators eager to see a rocket soaring toward orbit. For the fourth time in May, Elon Musk's commercial spaceflight company is preparing to send a Falcon 9 to deploy a batch of Starlink satellites into orbit following liftoff from Vandenberg Space Force Base in Vandenberg, California. SpaceX's famous two-stage rocket will likely get off the ground Thursday, May 22, to deliver more of the internet-beaming satellites into what's called low-Earth orbit – an altitude that allows for things like satellites to circle Earth fairly quickly. SpaceX always provides livestreams of its Starlink missions for the public to follow along, but for some in California, seeing the rocket launch may be as easy as stepping outside and looking up. Here's what to know about the SpaceX Falcon 9 rocket launch from Vandenberg Space Force Base in California, as well as when and where to watch it: What time is the SpaceX rocket launch from California? The SpaceX Falcon 9 rocket is slated to get off the ground as early as 3:03 p.m. PT (6:03 p.m. ET ) Thursday, with backup opportunities available until 5:51 p.m. PT, according to a launch alert from the Vandenberg Space Force Base. If SpaceX opts to scrub the launch, additional liftoff opportunities are available beginning at 1:36 p.m. PT Friday, May 23. 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. Will there be sonic booms? Residents of Santa Barbara County, San Luis Obispo County and Ventura County could hear sonic booms, according to an alert from Vandenberg Space Force Base in California. Sonic booms are brief, thunder-like noises that are often heard from the ground when a spacecraft or aircraft travels faster than the speed of sound.
