Stereo-B [NORAD 29511]

Stereo-B (Behind) is in a heliocentric orbit around the sun with its sister satellite, Stereo-A (Ahead). It was used for sun imaging and SEM monitoring. A planned test of the spacecraft’s automation just before the satellite passed behind the sun failed on 01-10-2014, causing the satellite to spin too quickly for the reaction wheels to correct it, resulting in a loss of communication with the spacecraft. After 22 months, on 21-08-2016, communications were restored and recovery attempts were performed through to September. On 23-09-2016, the carrier wave stopped being detected. It is suspected a frozen thruster valve came loose, increasing the spin rate even more. All subsequent attempts to find the satellite have failed.
