SpaceX uses a brand new Falcon 9 booster to deploy 51 Starlink satellites to orbit

SpaceX launched another batch of Starlink satellites to orbit from California after eight delays. The mission was delayed due to unfavorable weather conditions along the West Coast, including “15+ foot waves in the Pacific Ocean, as well as high winds across Central and Southern California,” shared SpaceX on January 13. Weather in the ocean must be favorable in order to recover the first-stage booster to reuse. The mission was also delayed for “pre-launch checkouts” of the rocket. SpaceX opted to use a brand new booster for this mission. Usually, the company reserves new boosters for its customers. The Falcon 9 finally lifted off on Thursday, January 19, at 7:43 a.m. PT from Space Launch Complex 4 East at Vandenberg Space Force Base, carrying 51 Starlink Group 2-4 satellites to Low Earth Orbit (LEO).  

 Approximately 8-minutes after liftoff, the new Falcon 9 first-stage booster (identified as B1075-1) returned from space with a propulsive landing on the ‘Of Course I Still Love You’ droneship which was stationed in the Pacific Ocean around 673 kilometers downrange. It marked SpaceX’s 166 landing of an orbital-class rocket. Recovering boosters enables the company to reuse in order to perform frequent cost-effective spaceflights. SpaceX is the only company in the world capable of such rocket reusability.  

This mission is referred to by the company as ‘Starlink Group 2-4’, it is the second launch of 51 satellites into the second orbital shell. SpaceX is arranging Phase 1 of the Starlink constellation into five orbital shells with different parameters. Orbital Shell 2 will consist of a total of 720 satellites divided into groups of 20 across 36 orbital planes in a 70° 570 kilometer orbit. Shell 2 will enable SpaceX to have Starlink coverage in around 94% of Earth. The 51 internet-beaming satellites were deployed by Falcon 9’s upper-stage nearly 30 minutes after liftoff. With this newly deployed batch, SpaceX now operates approximately 3,425 Starlink satellites in LEO which provide high-speed internet to over one million subscribers living across all seven continents.  SpaceX has approval from the U.S. Federal Communications Commission (FCC) to launch 7,500 next-generation Starlink satellites in the coming years.
