The SNAP science program requires photometric discovery and detailed follow-up observations of at least 2000 Type Ia supernovae with redshifts ranging from 0.3 to 1.7. The data are sent to a ground station and analyzed every few days in order to schedule a spectroscopic measurement near peak luminosity. The instrument consists of a 2-m three error anastigmat telescope with a 1.4 square degree FOV, a photometer that instruments 0.7 square degree of the FOV, and a low resolution spectrograph. Both the photometer and spectrograph use visible and NIR detectors to span the wavelength range 350 nm to 1700 nm. A 2D-symmetric array of fixed filters is deployed over the photometer sensors and the focal plane is operated in a step-and-stare mode to perform broadband photometry over fixed regions of the sky. The multi-object spectrograph is based on an image slicer. The R&D activities we are undertaking to insure technology maturity for a mission proposal will be presented.
