A little while ago, the SpaceX Dragon 2 spacecraft blasted off atop a Falcon 9 rocket from the Kennedy Space Center in its CRS-23 (Cargo Resupply Service 23) mission, also referred to as SPX-23. After almost exactly 12 minutes it separated successfully from the rocket’s last stage and went en route. This is the 23rd mission, the 3rd for the Dragon 2 version, for the Dragon spacecraft to resupply the International Space Station with various cargoes and then return to Earth, again with various cargoes.
