The story so far

  1. August 11: This became the lead update after today's public launch records changed.
  2. August 11: Executives made the schedule risk explicit: too much critical testing remains to treat a year-end debut as secure, even if the vehicle reaches Wallops on time.
  3. August 12: Both missions are now complete, turning two scheduled attempts into 53 additional satellites in orbit.

Interpretation

Why this matters

The mission cargo were routine; operating from both coasts within hours is the more useful measure of Falcon 9’s launch cadence.

Known facts

  • SpaceX launched two dozen of its Starlink satellites to low Earth orbit from Vandenberg Space Force Base. Liftoff happened at 9:46 p.m. PDT. The mission used Falcon 9 first stage B1103 on its fifth flight, and the booster landed on the droneship Of Course I Still Love You.
  • SpaceX launched 29 more of its Starlink internet satellites to orbit from Florida's Space Coast today (Aug. 11).
  • SpaceX launched 24 more of its Starlink global internet satellite constellation to orbit from California on Aug. 11, wrapping the second Starlink launch of the day.

Unknowns

  • Whether the target, status, webcast, or mission outcome changes again after the next public update.
