There have been six attempts to contact the STEREO Behind spacecraft using 70 meter stations between September 27 and October 9 without success. The last telemetry received from Behind was on September 18, and the last time the carrier wave was detected was on September 23. Recovery attempts for STEREO Behind have moved back to a monthly schedule until the spacecraft has returned to a point in its orbit where the attitude is in a favorable configuration for power and communications.
