Caption: Principal Investigator Terry Hurford poses with a 21-inch-diameter mirror originally built for a telescope that helped calibrate an engineering test unit of the Cassini Composite Infrared Spectrometer (CIRS). A CIRS team member found the mirror and Hurford is now repurposing it for the OPIS project.
