Abstract

The Supernova / Acceleration Probe (SNAP) is a space experiment to measure the properties of the accelerating universe and study both the dark energy and the dark matter of the universe. Each year, SNAP will discover and obtain high-quality data for ~ 2800 Type Ia supernovae in the redshift range 0.1 < z M) to +/-0.02, vacuum energy density (Ω Λ ) to +/-0.05, and curvature (Ω K) to +/-0.06. The data set can test the nature of the ``dark energy'' that is accelerating the expansion of the universe by measuring the ratio of the dark energy's pressure to its density to +/- 0.05, and by studying this ratio's time dependence. This project is supported by the US Department of Energy/Office of High Energy Physics.
