Northrop Grumman has launched NASA’s ICON mission aboard its Pegasus XL rocket on Thursday following a lengthy standdown that began during the initial attempt last November when an electrical short scrubbed the mission. The air-drop launch of Pegasus XL from underneath the L-1011 Stargazer aircraft occurred at 22:00 EDT (0200 UTC), 50-100 miles east of Daytona Beach, Florida.
