SpaceX Launches 23 Starlink Satellites in First Flight Since July 11 Anomaly

SpaceX successfully launched 23 of its Starlink broadband satellites into low Earth orbit (LEO) atop a Falcon 9 rocket from NASA's Kennedy Space Center in Florida, marking its first mission since a July 11 failure led to the loss of 20 Starlink spacecraft. The launch, which took place on July 27 at 1:45 a.m. EDT, marked the 17th launch and landing for the particular booster. The Falcon 9's first stage returned to Earth about eight minutes after launch, making a vertical touchdown on SpaceX's Just Read the Instructions drone ship in the Atlantic Ocean.

Key Takeaways:

  • SpaceX launched 23 Starlink broadband satellites into low Earth orbit (LEO) on July 27, marking its first mission since a July 11 failure.
  • The launch used a Falcon 9 rocket from NASA's Kennedy Space Center in Florida, and the first stage successfully returned to Earth, making a vertical touchdown on SpaceX's Just Read the Instructions drone ship.
  • The mission was the 17th launch and landing for the particular booster, with 13 of its flights being Starlink missions.
  • The July 11 failure resulted from a leak of liquid oxygen, which prevented the Falcon 9's upper stage from performing an orbit-raising burn as planned.
  • SpaceX's anomaly investigation found the likely cause of the leak to be a crack in a line for a pressure sensor in the liquid-oxygen system.
  • The Falcon 9's upper stage continued hauling the 23 Starlink satellites to LEO, deploying them right on schedule, about 63 minutes after launch.

Statistics:

  • 23 Starlink broadband satellites launched into low Earth orbit (LEO) on July 27.
  • The launch was the 17th launch and landing for the particular Falcon 9 booster.
  • 13 of the 17 launches by this particular booster were Starlink missions.
  • The July 11 failure resulted in the loss of 20 Starlink spacecraft.
  • The Falcon 9's upper stage failed to perform an orbit-raising burn due to a leak of liquid oxygen.
