A weather satellite set to bring new storm tracking capabilities to the western United States and the Pacific Ocean rode into space atop a United Launch Alliance Atlas 5 rocket Thursday.

Early Friday morning, the 8-million-pound mobile service tower was retracted from around the Atlas 5 rocket, revealing the 189-foot-tall vehicle for liftoff from Vandenberg Air Force Base, California, carrying the commercial WorldView 4 Earth-imaging satellite.
