GLAST has a launch date of next Tuesday, June 2. The telescope is now on the launch pad atop a Delta II rocket. The space-borne observatory
"will open a wide window on the universe through the study of Gamma rays, the highest-energy form of light. GLAST data will enable scientists to answer persistent questions across a broad range of topics, including supermassive black-hole systems, pulsars, the origin of cosmic rays, and searches for signals of new physics."
GLAST could help scientists get closer to answering what Dark Matter is made of. A more complete list of the science that this instrument will undertake is here.
