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.”

The MIGHTI FMA sensor is currently going through proto-flight vibration testing. FMB completed testing 2 weeks ago. Final optical tests will be performed after vibration then both A and B will be packed up and shipped to Space Dynamics Laboratory (SDL) in Logan Utah on December 9, 2015. Once at SDL it will go through Thermal Vacuum and Calibration activities prior to delivery to ICON at the end of January 2016.
