SpaceX poised to launch 21 new Starlink satellites on Falcon 9 rocket

SpaceX launched another batch of its Starlink internet satellites early Tuesday (Sept. 12) and landed the returning rocket on a ship at sea.

A SpaceX Falcon 9 rocket launched 21 Starlink craft from California’s foggy Vandenberg Space Force Base on Tuesday at 2:57 a.m. EDT (0657 GMT; 11:57 p.m. Sept. 11 local California time). 

The Falcon 9’s first stage returned to Earth as planned for a landing in the Pacific Ocean, on the SpaceX droneship Of Course I Still Love You, about 8.5 minutes after launch.

This was the 11th launch and landing for this first-stage booster, according to the SpaceX mission description on the company’s website.

The Falcon 9’s upper stage is scheduled to deploy the Starlink satellites about 62 minutes after liftoff.

Tuesday morning’s launch was the 64th of 2023 for SpaceX, which is blowing past the record it set last year with 61 launches. 

SpaceX is outpacing the rest of the world in space missions this year, with the majority of its launches supporting the company’s Starlink megaconstellation. 

The total number of operational Starlink satellites in orbit currently exceeds 4,600, according to astrophysicist Jonathan McDowell, who tracks the constellation on his website, and SpaceX hopes to increase the number to as many as 42,000 over the long haul.
