Q&A with Curt Blake, president of Spaceflight Industries (members only)

The world’s most powerful operational rocket flashed to life at 2:30 a.m. EDT (0630 GMT) Tuesday and climbed into a moonlit summer sky from pad 39A at NASA’s Kennedy Space Center in Florida, the same site where the Apollo 11 astronauts left Earth for their historic moon landing nearly 50 years ago.

SpaceX test-fired the Falcon 9 rocket early Saturday ahead of launch with the next four astronauts heading to the International Space Station. The static fire test before sunrise Saturday in Florida was a major step toward liftoff Thursday.

After a terminal countdown abort Sunday night, SpaceX launched a Falcon 9 rocket with the next 60 Starlink internet satellites Thursday at 3:24 a.m. EST (0824 GMT). The Falcon 9 took off from pad 39A at the Kennedy Space Center, and its first stage booster successfully landed on SpaceX’s offshore drone ship in the Atlantic Ocean.
