  High energy polarization can be an indication of geometry, orientation, and
other physical phenomena for a variety of sources, but has heretofore been a
virtually unmeasured phenomenon. PoGOLite is a balloon-borne instrument
intended to measure the polarization of X-rays between 25 and 100 keV. The
pathfinder version of the instrument is scheduled to be launched from northern
Sweden in summer 2013. The primary targets are the Crab pulsar and nebula and
Cygnus X-1.
