A robotic space shuttle with stubby wings, tail fins, its belly covered with black thermal tiles, clam-shell doors that swing open to reveal a payload bay and a solar array for ultralong-duration missions rode into orbit Wednesday on the fourth mission of the Air Force’s reusable X-37B spaceplane project.

Rocket Lab’s second launch from Virginia took off at 6:38 p.m. EDT (2238 GMT) Thursday. The company’s carbon fiber Electron small satellite launcher carried two commercial radar remote sensing satellites into orbit for Capella Space.

Orbital ATK’s Antares rocket will deliver the commercial Cygnus supply ship to an orbit with an altitude between 117 miles (189 kilometers) and 184 miles (296 kilometers) within about nine minutes of liftoff Saturday from Virginia’s Eastern Shore.
