Abstract The Ramaty High Energy Solar Spectroscopic Imager (RHESSI) spacecraft was launched on February 5, 2002. With two years of operation on-orbit, its Sunpower M77 cryocooler is maintaining the array of nine germanium detectors at 86K, at higher temperature and input power than intitial conditions. As commercial coolers similar to this are of some interest for other flight instruments, we offer an update on its status and health, and discuss the prospects for continued operation.
