The 52 satellites, each a little more than a quarter-ton, will use krypton-fueled ion thrusters to maneuver into their operating orbits at an altitude of 335 miles (540 kilometers), joining the rest of the Starlink fleet providing global internet service. With the newest batch of satellites, SpaceX has launched 1,944 Starlink spacecraft since May 2019.
A tabulation maintained by Jonathan McDowell, an astrophysicist and widely-respected tracker of spaceflight activity, showed that before the Starlink 4-4 mission, SpaceX had 1,729 functioning Starlink satellites in orbit. Of those, 1,467 satellites are operational, while the rest are still maneuvering into their slots in the constellation, or are otherwise working but not providing internet service. (...)

More than seven months since her most recent flight, B1051 was transported to the pad last week and underwent a customary Static Fire Test of her nine Merlin 1D+ engines early Friday. SpaceX announced shortly thereafter that it was targeting 1:24 a.m. PST Saturday for launch, but late Friday this T-0 was nudged to the backup opportunity a little more than three hours later at 4:41 a.m. PST.
The record-setting booster for last night’s flight first entered service in March 2019, when she delivered an unpiloted Crew Dragon to the International Space Station (ISS) for the critical Demo-1 mission in support of the Commercial Crew Program. She then lifted Canada’s three-spacecraft Radarsat Constellation Mission (RCM) the following June. Those two opening missions of her career saw B1051 fly both from historic Pad 39A at the Kennedy Space Center (KSC) in Florida and from SLC-4E at Vandenberg.
In 2020, she became the first Falcon 9 core to launch four times and five times in a single calendar year. Just last January, she established a new record—now beaten—for the shortest launch-to-launch interval of an orbital-class booster. And in 2021, she became the first Falcon 9 core to record eighth, ninth, tenth and now 11th missions. (...)
