Resuming space launches from the U.S. Western Range at Vandenberg Air Force Base in California after a half-year infrastructure outage, an Atlas 5 rocket will boost a commercial Earth-imaging bird into orbit on Friday.

A SpaceX Falcon 9 rocket lifted off from Space Launch Complex 4-East at Vandenberg Air Force Base in California at 12:17 p.m. EST (9:17 a.m. PST; 1717 GMT) Saturday with an oceanography satellite jointly developed by U.S. and European space and weather agencies. The rocket’s first stage booster returned to a bullseye landing back at Vandenberg.

A large rocket stage left in space after the successful launch of China’s heavy-lift Long March 5B rocket May 5 fell into the atmosphere Monday over the Atlantic Ocean, becoming the most massive object in nearly 30 years to perform an uncontrolled re-entry from orbit.
