On Tuesday, May 27, at just after 7:30 P.M. Eastern Time, Starship Flight 9 lifted off the launchpad in Starbase, Texas. The launch was a first for Starship, since it was the first time SpaceX were going to refly a Super Heavy booster, using the one flown on Flight 7. As part of reflying the booster, SpaceX put the booster through a battery of tests, intending to test how it would respond to a variety of situations. As well as reflying a booster, SpaceX hoped to deploy a set of Starlink simulators using the Ship upper stage.
