Christmas Eve Launch of the Cosmic Ray Electron Synchrotron Telescope (CREST)
On Christmas Eve 2011, the balloon-borne CREST instrument was successfully launched from McMurdo Station, Antarctica. It is now safely on the ground after completing a 10-day orbit of Antarctica at altitudes between 110,000-120,000 feet. Recovery operations are still in progress. CREST is designed to observe ultra-high energy (multi-TeV) electrons in the cosmic radiation to discover how they are accelerated. CREST is a Collaboration between The University of Michigan, Indiana University, Pennsylvania State University, the University of Chicago and Northern Kentucky University. The Michigan group, led by Professor Gregory Tarlé and consisting of Associate Research Scientist Michael Schubnell, Graduate Student Joseph Gennaro and Electronics Engineer Jon Ameel, was responsible for the flight computer and electronics.
