PICO: Probe of Inflation and Cosmic Origins
  The Probe of Inflation and Cosmic Origins (PICO) is a proposed probe-scale
space mission consisting of an imaging polarimeter operating in frequency bands
between 20 and 800 GHz. We describe the science achievable by PICO, which has
sensitivity equivalent to more than 3300 Planck missions, the technical
implementation, the schedule and cost.
