On Nov. 19, Northrop Grumman flew the L-1011 Stargazer and Pegasus XL rocket carrying ICON back to Vandenberg Air Force Base in California. On Nov. 20, they completed the de-mate of Pegasus from the L-1011 and transported the rocket safely into the integration facility. The Northrop Grumman/NASA team continues its investigation into the off-nominal data observed during the Nov. 7 launch attempt. Once the analysis is complete, a new launch date will be determined.

NASA and Northrop Grumman have postponed today’s (Nov. 7)  launch attempt of NASA’s Ionospheric Connection Explorer, or ICON, mission due to off-nominal data observed on the Pegasus XL rocket, during the captive carry flight. The L-1011 Stargazer carrier aircraft returned to Cape Canaveral Air Force Station in Florida and the team will begin an investigation into the issue. The ICON spacecraft remains healthy. The team is evaluating the next launch attempt.

Continuing a series of delays keeping NASA’s Ionospheric Connection Explorer on Earth, NASA announced Tuesday that the satellite’s launch aboard an air-dropped Northrop Grumman Pegasus XL rocket will not occur as scheduled Friday.

The $252 million science mission was set launch from an airborne carrier jet around 4:05 a.m. EDT (0805 GMT) Friday, but NASA said Tuesday mission managers decided to delay the flight “to conduct further pre-launch testing on the rocket.”
