Balloon-borne astronomy experiment X-Calibur racing to hit wind window

In a few days, a balloon-borne telescope sensitive to the polarization of high-energy “hard” X-rays will ascend to the edge of the atmosphere above Fort Sumner, N.M. Once aloft, the telescope will stare at black holes, neutron stars and other exotic astronomical objects that shine brightly in the X-ray part of the spectrum in order to learn about their nature and structure. After years of preparation, the X-Calibur team is racing to get the experiment mission-ready in time for the stratospheric wind event they hope to ride.
