BRRISON GROUND CALIBRATION - BIRC RAW DATA V1.0

This mission was performed by The Johns Hopkins University Applied Physics Laboratory (APL) to develop and fly a balloon-borne gondola with a scientific payload for the observation of Comet ISON and other planetary objects, during a one-day flight demonstration in September 2013. The mission was flown on the evening of September 28, 2013, just 11 days after the originally targeted launch date of September 17.

Ascent to float altitude lasted about 2 hours. During the very early phase of commissioning, an anomaly occurred that caused the telescope to rapidly retract to the stowed orientation and become stuck in that orientation. Efforts were made to free the telescope to no avail.
