Q&A with Elon Musk, founder and CEO of SpaceX (members only)

The four-member crew will now fly onboard Dragon Endurance instead of SpaceX’s fifth Crew Dragon spacecraft as originally intended. Launch has moved up to Wednesday, March 12, “pending mission readiness and completion of the agency’s certification of flight readiness process.”

Liftoff of the Starlink 17-23 mission occurred at 2:10:39 a.m. PST (5:10:39 a.m. EST / 1010:39 UTC). The rocket, carrying 25 Starlink V2 Mini satellites, took southerly trajectory on departure from Vandenberg Space Force Base.

For the third time in 10 days, SpaceX is readying a Falcon 9 rocket for launch Sunday from Florida’s Space Coast with another 60 Starlink internet satellites. This time, SpaceX aims to extend the record for reusing a Falcon 9 booster to nine flights.
