Video: Falcon 9 launch replays

NASA announced Monday that the launch of the first operational crew rotation mission to the International Space Station on SpaceX’s Crew Dragon spacecraft is set for the predawn hours of Halloween, eight days later than previously planned.

United Launch Alliance said Thursday it is targeting Sept. 26 for the next attempt to send a classified U.S. government spy satellite into orbit aboard a Delta 4-Heavy rocket, following an abort Aug. 29 just three seconds before liftoff from Cape Canaveral.

NASA’s Tracking and Data Relay Satellite-M, a communications router for the space station and dozens of science spacecraft, blasted off from Cape Canaveral at 8:29 a.m. EDT on Friday atop a United Launch Alliance Atlas 5 rocket.
