SpaceX pulled-off a predawn launch with Starlink G4-17 mission.
53 satellites placed in orbit by the Falcon9 'core' B1058.12
May 6, 2022 SpaceX launched today – Friday, May 6th, the Falcon 9 B1058.12 rocket with fifty-three Starlink satellites into orbit with inclination of 53.2 degrees northeast azimuth with perigee of 325 km and apogee of 337 km. The rocket lifted off from Launch Complex 39A at the Kennedy Space Center in Florida at 05:42 EDT (09:42 UTC), just few hours after the SpaceX's NASA Crew-3 landing and recovery, which took place at Gulf of Mexico. This launch is the 44th Starlink mission was named Starlink Group 4-17.
The first B1058.12 stage of this mission previously launched Crew Demo-2, ANASIS-II, CRS-21, Transporter-1, Transporter-3 and six other Starlink missions. After stage separation, Falcon 9's first stage landed on the ferry A Short Fall of Gravitas , and towed by the ship Doug and stationed in the Atlantic Ocean 634 km from the Cape; The shells of the head fairing fell from parafoil at about 643 km and were 'fished' in the sea by the recover vessel Bob, and second stage re-entry after two ignitions (SECO-1 and 2) occurred in South Australia.
The mass of a Starlink v1.5 satellite is about 300 kg after adding ISL laser terminals (it's previous versions are 270 kg). Each satellite features a compact flat-panel design that minimizes bulk, allowing a 'dense launch stack' to take full advantage of Falcon 9's payload launching capabilities.
