A little while ago SpaceX’s Crew Dragon spacecraft blasted off atop a Falcon 9 rocket from Cape Canaveral in its SpX-DM2 (SpaceX Demonstration Mission 2) or SpaceX Demo-2 mission. After about eleven minutes, it successfully separated from the rocket’s last stage and went en route to carry out its mission. This is the first crewed mission of the Crew Dragon spacecraft, in this case with Doug Hurley and Bob Behnken on board.
