Watch the Falcon 9 launch from pad 39A

NASA launch commentator George Diller called the Atlas 5 with Cygnus, his final liftoff as the voice of launch control before retirement next month. He has worked at the Kennedy Space Center for nearly four decades and served as the commentator for such memorable launches as Hubble, Cassini, Mars Pathfinder, the Spirit, Opportunity and Curiosity rovers and the final space shuttle mission.

Nearly a decade in the making, NASA and SpaceX have set May 27 as the target launch date for the first crewed space mission to launch into orbit from U.S. soil since the retirement of the space shuttle in 2011.

SpaceX launched its huge Starship rocket on the program’s eighth test flight Thursday, but a malfunction of some sort triggered multiple upper stage engine shutdowns and for the second flight in a row, the vehicle failed to reach its planned sub-orbital altitude and broke apart in a shower of debris.
