The SpaceX Falcon 9 rocket and the Crew Dragon spacecraft taking the astronauts to the ISS are already positioned at Kennedy Space Center’s Launch Complex 39A.

SpaceX has just test-fired the Falcon 9’s first-stage engines as part of the final series of tests needed before launch.

The Demo-2 mission team still has to complete a final readiness review, which will incorporate data from the critical static fire test, on May 25th.
