Dec. 7 (UPI) — SpaceX launched another 28 satellites into low-Earth orbit Sunday, the company announced.

In a news release, SpaceX said the satellites were launched by a Falcon 9 rocket from Space Launch Complex 4 East at the Vandenberg Space Force Base in California around 9:58 a.m. local time.

“This was the 12th flight for the first stage booster supporting this mission, which previously launched NROL-126, Transporter-12, SPHEREx, NROL-57, and now eight Starlink missions,” SpaceX said in the news release.

After stage separation, the first stage booster landed on a floating barge in the Pacific Ocean.

“There was a possibility that residents of Santa Barbara, San Luis Obispo, and Ventura counties may have heard one or more sonic booms during the launch, but what residents experienced depended on weather and other conditions,” SpaceX said.

SpaceX has another launch scheduled for later Sunday from NASA’s Kennedy Space Center in Florida, with that rocket due to deliver another 29 Starlink satellites into orbit.
