A few hours ago SpaceX Dragon spacecraft blasted off atop a Falcon 9 rocket from Cape Canaveral in its CRS-9 (Cargo Resupply Service 9) mission, also referred to as SPX-9. After almost ten minutes it separated successfully from the rocket’s last stage and went en route. This is the ninth mission to send the Dragon spacecraft to the International Space Station with various cargoes and then return to Earth, again with various cargoes.
