Live coverage: Falcon 9 disintegrates after launch

The Crew Dragon and Falcon 9 rocket roll to the launch pad on a foggy Florida morning before going upright shortly before sunset later in the day.

SpaceX kicked off Memorial Day weekend with an overnight launch Saturday from Cape Canaveral, boosting a nearly five-ton communications satellite into orbit for Arabsat, a multinational consortium providing TV and video broadcast services across the Middle East.

The NASA manager overseeing development of Boeing and SpaceX’s commercial crew ferry ships says the space agency has approved SpaceX’s proposal to strap in astronauts atop Falcon 9 rockets, then fuel the launchers in the final hour of the countdown as the company does for its uncrewed missions.
