Photos: Atlas 5 rocket soars from West Coast

SpaceX has delayed liftoff of its next cargo ship bound for the International Space Station until Friday, setting up a one-shot attempt to launch the commercial supply carrier from Cape Canaveral before a potential slip to late December due to high solar angles in orbit.

An early bird rocket launch from the Florida spaceport will take to the skies before dawn Saturday when an Atlas 5 lofts a classified U.S. government satellite.

Despite a growing number of rocket options, the availability of on-time launch services remains a key factor in getting BlackSky’s constellation of Earth-imaging smallsats into orbit. SpaceX’s rideshare launch service will give BlackSky a chance to add two more spacecraft to its fleet on a Falcon 9 rocket with the next batch of Starlink Internet payloads.
