All of the scientists, engineers, pilots, and crew onboard the NASA DC-8 and the NASA Airborne Science Program support staff on the ground were deeply saddened by the launch failure of the Glory satellite. For more information about the specifics of what went wrong, watch the NASA news conference. For information on what the loss of Glory means to climate science, see here.
The NASA DC-8 left its home base at the NASA Dryden Aircraft Operations Facility in California at 9:47PM PST.

The DC-8 flew 1800 miles south to 7.5N 120W (a spot over the Pacific Ocean 2800 miles off the coast of Panama) where it circled for approximately thirty minutes at 41,000 ft, waiting to track the launch at 2:09 AM PST.

Instruments installed on the DC-8 by the KTech Corporation first detected Glory approximately four minutes after launch and tracked it for ten additional minutes. The failure of the fairing (a protective cover) to separate approximately three minutes after launch was revealed in Glory’s unexpected trajectory.
Telemetry data collected by the NASA DC-8 and from other locations will be used to better understand what went wrong.

|The NASA ER-2 in flight|
After the ER-2 returned, instrument scientists from NASA’s Goddard Space Flight Center were literally jumping and yelling for joy in the hangar at Dryden when they took their first look at the data!
Wind profile data collected by TWiLiTE will be important for analyzing atmospheric dynamics, for weather predictions, and for understanding Earth’s hydrological cycle. Data reduction and processing is now in progress. The data will also be compared with ground validation measurements to verify TWiLiTE’s performance.

The TWiLiTE instrument was developed with funding from the Earth Science Technology Office as a demonstration for the 3D-WINDS Global Wind Space Mission. ER-2 flight testing of TWiLiTE was provided by the NASA Airborne Instrument Technology Transfer program.
