Important notice about STEREO Behind


The STEREO Ahead observatory is back to normal operations on the main lobe of the high gain antenna.

Communications with the STEREO Behind spacecraft were interrupted on October 1, 2014 immediately after a planned reset of the spacecraft performed as part of a test of solar conjunction operations. The spacecraft telemetry indicated an anomaly in the guidance and control system, but this is still being evaluated. No further communications have been successful since Oct. 1st. Follow this link for more information.

Attempts to reestablish communications with the STEREO Behind spacecraft are ongoing.

Launched in 2006, the STEREO mission achieved its prime science goals within the two-year prime mission, but continues to explore solar and heliospheric activity through the current solar maxmimum and beyond.
