 SNAP, the SuperNova/Acceleration Probe, is one of three concepts competing for NASA and DOE's Joint Dark Energy Mission (JDEM).
The National Research Council's Beyond Einstein Program Assessment Committee has recommended that the Joint Dark Energy Mission (JDEM), jointly supported by the National Aeronautics and Space Administration and the Department of Energy, be the first of NASA's Beyond Einstein cosmology missions to be developed and launched.
One of the three competing projects in the JDEM program is Lawrence Berkeley National Laboratory's SuperNova/Acceleration Probe, or SNAP, a versatile space-borne observatory with a powerful two-meter-class telescope and a half-billion pixel imager, designed to study dark energy by recording the distance and redshift of some 2,000 Type Ia supernovae a year and mapping the sky with unprecedented resolution. Dark energy is the name given to the mysterious entity which is causing the universe to expand ever more rapidly. It accounts for nearly three-quarters of all the energy in the universe.
