A few hours ago, Northrop Grumman’s Cygnus XL spacecraft blasted off atop a SpaceX Falcon 9 rocket from Cape Canaveral on its NG-23 or CRS NG-23 mission. After about 15 minutes, it successfully separated from the rocket’s last stage and set on its course. This is the third resupply mission to the International Space Station with various payloads launched using the Falcon 9 rocket while waiting for the new version of Northrop Grumman’s Antares rocket to be ready. It’s also the first to see the use of the new version of the Cygnus cargo spacecraft.
