Results After a successful on-orbit insertion, SNaP-1 was not contacted until 6 January 2014 when the spacecraft experienced near full sun on-orbit conditions (high beta). It was discovered that the spacecraft went into power saver mode during initial de-tumble maneuver. Due to high momentum in the vehicle the spacecraft was never able to de-tumble leaving it unable to maintain sun-tracking. Contact was lost shortly after the end of on-orbit full sun conditions.
Failure cause High tumble and contact lost after full Sun illumination conditions ended.
