HOUSTON, June 14: An innovative X-ray telescope blasted off aboard an unmanned air-launched rocket yesterday to begin a two-year mission to ferret out black holes and other high-energy celestial phenomena in space, NASA officials said. The Nuclear Spectroscopic Telescope Array, nicknamed NuStar, shot toward orbit aboard a Pegasus XL rocket seconds after being released from an aircraft flying about 40,000 feet over the Pacific Ocean south of the Kwajalein Atoll in the Marshall Islands.
