Important notice about STEREO Behind

Status

The STEREO Ahead observatory is currently performing as expected, and taking science data on a regular basis.

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. On Sunday, August 21, contact was reestablished with the STEREO Behind spacecraft for the first time in 22 months. Follow this link for more information.

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.
