+    ** proposing to ESA (6 March deadline), building up a consortium for a larger 3 year cubesat project.  Will study the performance gains for a larger mission (e.g. CORE)
+    ** The idea: a piggyback satellite that autonomously deploys and positions itself.  Attitude and orbital control are the key issues.
+    ** goal is a few kg mass, and cost ~ 1% of total cost of mission.
+    ** The idea is to "Calibrate Everything"!  Polarization angle, photometry, main beams, far sidelobes.
+       * Cover wide frequency band: 10's of GHz, 40-400 GHz originally conceived.
+       * Monochromatic tones that can be swept in frequency.
+     * Future ESA work will study some key trades, cost, mass, etc., and even possibly look at hardware demos.
+   * Do Galactic science need better than 1 degree precision in polarization angle?
