CMBPol Mission Concept Study Stephan Meyer Unversity of Chicago July 28, 2008
this study? o enhance the priority of inflation science within the funding agencies. There is an opportunity to do this because the 2010 NRC Decadal Surve of Astrophysics will begin its wor in the Fall 2008 and accept input from communities through early 2009.

Decadal Surveys 1990 Bahcall 2000 McKee-Tayl he surveys take an overview of the state of astrophysics and make a prioritized list of recommendations for the upcoming decade.
