SpaceX's rocket got off the ground six times in May from Vandenberg Space Force Base and is due to make its next delivery of Starlink satellites.

SpaceX on Wednesday afternoon launched another batch of 27 Starlink satellites to low-Earth orbit from Vandenberg Space Force Base in California on the 15th anniversary of the first Falcon 9 rocket launch.

A SpaceX Falcon 9 rocket launch took place Wednesday night from the Vandenberg Space Force Base in California. The rocket launched Starlink V2 Mini optimized satellites into low-Earth orbit.

Liftoff, as usual, will take place from the Vandenberg Space Force Base. The two-stage 230-foot-tall rocket, one of the world's most active, has become crucial in regularly deploying batches of internet-beaming Starlink satellites into what's called low-Earth orbit — an altitude that allows for things like satellites to circle Earth fairly quickly.

The company is developing a larger vehicle, named Helios, that could meaningfully improve the ability of SpaceX's Falcon 9 and Falcon Heavy to transport large payloads to the Moon, Mars, and other destinations in the Solar System.

About 8 minutes later, the Falcon's first stage returned to Earth, landing vertically on the ocean-based droneship "Of Course I Still Love You." This was the 25th flight for this booster, including 14 previous Starlink launches, according to SpaceX's website for Saturday's mission.

A SpaceX spacecraft has caused a sonic boom over California as it returned to Earth's atmosphere, and some on social media initially mistook the sound for an earthquake. One even thought a bomb had gone off.

The next rocket launch from Vandenberg Space Force Base in Southern California is due to liftoff Friday, May 16.

About 8.5 minutes after liftoff, the booster landed safely on SpaceX's Of Course I Still Love You drone ship, stationed in the Pacific Ocean. This was the 450th successful landing of a Falcon 9 rocket, according to SpaceX.
