NASA and Northrop Grumman completed a test flight of the L-1011 Stargazer aircraft from Cape Canaveral Air Force Station in Florida on Sunday, Oct. 28. Carrying Pegasus and NASA’s Ionospheric Connection Explorer (ICON), the 4-hour, 45-minute flight tested the aircraft’s systems prior to launch.

A new launch date for the ICON mission will be determined after the team finishes processing and reviewing the data.
