[61.01] Overview of the SNAP Primary Science Mission

S. Perlmutter (LBNL), SNAP Collaboration

The SuperNova / Acceleration Probe (SNAP) is a dedicated cosmology satellite mission, now in its study phase. The talks of this session will provide an introduction to the design and goals of this project. With a 1-square-degree imager and an optical-to-near-IR spectroscopy system, SNAP is able to find thousands of supernovae, and follow them through their rise and fall with high-signal-to-noise photometry and spectra. The same data set will allow several complementary cosmology approaches, including a weak-lensing survey. Together, the resulting cosmological measurements will dramatically improve our constraints on the cosmological parameters, and in particular address the properties of the ``dark energy" of the universe that apparently dominates over the dark matter energy, accelerating the expansion.

This research has been supported in part by the United States Department of Energy and the National Science Foundation.
