Measurement of the polarization of the Cosmic Microwave Background (CMB) has the potential to provide one of the few quantitative observable consequences of the inflationary epoch. A community-wide study of the theory, analysis, instrumentation and technology is being supported by a NASA Mission Concept Study grant. This study will culminate in a report to NASA and to the 2010 NRC Decadal Survey Committee on Astrophysics with recommendations for the most expeditious path to realizing that potential.
