Current and Proposed CMB Programs/Facilities

Direct observations of the CMB are uniquely within the purview of RMS astronomy and huge advances have occurred in the last decade, thanks to a coordinated strategy of both space- and ground-based programs. A Task Force on the overall US CMB research program (TFCR) will soon report to the Astronomy and Astrophysics Advisory Committee and HEPAP; we are trying to avoid duplicating the efforts of the TFCR. The TFCR charge can be found at this link to the HEPAP page.

For the purpose of educating our RMSPG on the state of CMB experiments, we include here a draft compilation of both space and ground based CMB experiments either in the data analysis phase, operational or in development. We fully recognize that this list is probably not complete and apologize in advance to any projects which feel slighted by omission here. Absence of a project from this list carries no significance other than the lack of time/effort on the part of the RMSPG. Please feel free to suggest additions/corrections to this page by writing to Martha Haynes.
