Important notice about reduced STEREO science operations

Status

The STEREO Ahead spacecraft is currently in "safe mode" for superior solar conjunction. Normal operations are expected to resume in July 2015. See this important notice for more information.

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.
