This is a saved data archive of the Balloon Rapid Response for Comet ISON
(BRRISON) mission. 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. The anomaly and its cause will not be
discussed in this archive. Instead, a full description of the anomaly, its
cause, and recommended corrective actions is provided in the 'BRRISON
Anomaly Investigation Team Final Report.'
