The addition of a U.S. Air Force communications satellite has capped the assembly of a 218-foot-tall United Launch Alliance Delta 4 rocket at Cape Canaveral set for liftoff the evening of March 13.

Rocket Lab’s Electron rocket took off at 1:12 a.m. EDT (0512 GMT) Saturday carrying five payloads for the National Reconnaissance Office, NASA and the University of New South Wales at Canberra in Australia. The launch was the first for Rocket Lab since January due to delays related to the coronavirus pandemic.

SpaceX launched a Falcon 9 rocket Thursday from Cape Canaveral with the U.S. Space Force’s newest third-generation Global Positioning System navigation satellite, helping clear the way for the launch of SpaceX’s first operational Crew Dragon astronaut mission later this month.
