SpaceX Mission Audio
Keeping up a rapid-fire launch cadence to begin 2022, SpaceX launched launch another Falcon 9 rocket Tuesday night from Kennedy Space Center in Florida with 49 Starlink internet satellites.
Liftoff from pad 39A occurred at 9:02:40 p.m. EST Tuesday (0202:40 GMT Wednesday) to kick off a 15-minute launch sequence before deploying the 49 flat-panel Starlink satellites into orbit.
SpaceX delayed the launch from Monday night to wait for better conditions in the booster recovery zone in the Atlantic Ocean. The mission was again delayed from an earlier launch opportunity at 7:04 p.m. EST Tuesday (0004 GMT Wednesday), without explanation.

The 229-foot-tall Falcon 9 rocket arced southeast from Kennedy Space Center to deploy the Starlink payloads into an orbit inclined 53.2 degrees to the equator. The mission aimed to release the Starlink satellites at T+plus 15 minutes, 32 seconds, into an orbit ranging in altitude between 130 miles and 210 miles (210 by 339 kilometers).
This mission, designated Starlink 4-6, was SpaceX’s third Falcon 9 launch of the year. The first stage booster, tail number B1060, made its 10th trip to space and back.
SpaceX’s drone ship “A Shortfall of Gravitas” was on station in the Atlantic Ocean north of the Bahamas for landing of the first stage booster.
