PRISM (Polarized Radiation Imaging and Spectroscopy Mission): An
  Extended White Paper
  PRISM (Polarized Radiation Imaging and Spectroscopy Mission) was proposed to
ESA in May 2013 as a large-class mission for investigating within the framework
of the ESA Cosmic Vision program a set of important scientific questions that
require high resolution, high sensitivity, full-sky observations of the sky
emission at wavelengths ranging from millimeter-wave to the far-infrared.
PRISM's main objective is to explore the distant universe, probing cosmic
history from very early times until now as well as the structures, distribution
of matter, and velocity flows throughout our Hubble volume. PRISM will survey
the full sky in a large number of frequency bands in both intensity and
polarization and will measure the absolute spectrum of sky emission more than
three orders of magnitude better than COBE FIRAS. The aim of this Extended
White Paper is to provide a more detailed overview of the highlights of the new
science that will be made possible by PRISM
