The Ramaty High Energy Solar Spectroscopic Imager (RHESSI) spacecraft was launched on February 5,2002. With more than a year of operation on-orbit, its Sunpower M77 cryocooler continues to maintain the array of nine germanium detectors at 7% Trends have begun to emerge in cryocooler power and vibration, suggesting that the cooler's operating point is slowly changing. Possible causes are identified and discussed.
