A few hours ago SpaceX Dragon spacecraft blasted off on a Falcon 9 rocket from Cape Canaveral in its CRS-8 (Cargo Resupply Service) mission, also referred to as SPX-8. After about twelve minutes it successfully separated from the rocket’s last stage and went en route. This is the 8th of 12 missions that include sending the Dragon spacecraft to the International Space Station with various cargoes and then return to Earth, again with various cargoes.
