SpaceX to Begin December at Vandenberg with 27 Starlink Launches on Monday

SpaceX is kicking off its December launches at Vandenberg Space Force Base in California by sending the 27 Starlink satellites to low-Earth orbit from the Space Launch Complex 4 East (SLC-4E) at night on December 1, 2025. 

This will be the 20th flight for the first stage booster supporting the mission, which has also launched Crew-7, CRS-29, PACE, Transporter-10, EarthCARE, NROL-186, Transporter-13, TRACERS, NROL-48, and 10 Starlink missions, according to SpaceX. 

Following stage separation, the Falcon 9 rocket is expected to land on the ‘Of Course I Still Love You’ droneship, which will be stationed in the Pacific Ocean. 

A live webcast of the mission will begin roughly five minutes before lift off and can be viewed on the SpaceX website, on X, and on the X TV app.

Residents of Santa Barbara, San Luis Obispo, and Ventura counties may hear one or more sonic booms during the launch, SpaceX said. However, weather and other factors determine what residents will hear. 

A sonic boom is a brief, thunder-like noise that residents can hear when a rocket travels faster than the speed of sound. While sonic booms do not usually cause injuries, the loud sound can startle and awaken residents. 

In addition to the upcoming launch in California, SpaceX launched 29 Starlink satellites into orbit from NASA’s Kennedy Space Center in Florida on December 1 at 2:44 a.m. ET (November 30 at 11:44 p.m. PT).

About Starlink

Starlink is an advanced satellite constellation that uses a low Earth orbit to deliver broadband internet capable of supporting streaming, video calls, online gaming, and more. 

Starlink is a constellation of thousands of satellites orbiting the planet much closer to Earth, at nearly 550 km, and covers the entire Earth. Since the satellites are in a low orbit, latency is much lower, around 25 ms compared to 600+ ms, according to SpaceX. 

Currently, more than 6,750 satellites are in orbit, serving millions of users with high-speed, low-latency internet, the company stated on its website.

One of the largest satellite constellation operators in the world, Starlink has introduced a space safety service to ease coordination with other satellite operators and launch service providers. 

Starlink’s satellites are produced and operated in Redmond, Washington, while Starlink Kits for customers are manufactured in Bastrop, Texas. Together, the satellites and kits deliver high-speed, low-latency internet globally. 

The satellites feature a compact, flat-panel design that reduces volume, enabling a dense launch stack to take maximum advantage of the Falcon 9’s launch capabilities.
