The SNAP satellite couples an extremely stable 2.0 m space telescope to a one square degree focal plane. This is instrumented with a combination of fully depleted optical CCDS and HgCdTe near-infrared sensors, providing multi-band imaging from 400 to 1700 nm. A pick-off within the focal plane feeds a low resolution (R~150) integral field spectrograph with wavelength coverage from 600 to 1700 nm. This satellite will be used to conduct an optical-NIR survey of more than 20 square degrees to a depth of 32 AB magnitudes. We describe briefly essential features of the SNAP mission design, with an emphasis on recent advances. We also describe basic parameters of the SNAP survey. This description provides the context for understanding the science reach of SNAP.
