After a lull in launch activity this fall, SpaceX teams at Cape Canaveral are preparing for up to four Falcon 9 missions in December to close out 2019 with a surge of launches.

A commercial Cygnus resupply craft that received a new corporate owner while berthed at the International Space Station — thanks to Northrop Grumman’s acquisition of Orbital ATK in June — departed the research complex Sunday. The supply ship was released by Canadarm 2 on the space station at 8:37 a.m. EDT (1237 GMT).

NASA says initial checks show no damage to the Atlas 5 rocket or the agency’s asteroid-bound OSIRIS-REx spacecraft that stood within the Vertical Integration Facility just a mile away from the SpaceX explosion Thursday.
