"NASA's newest space telescope will start searching the universe for black holes on Wednesday. Scientists hope the NuSTAR X-ray telescope, which launched about six weeks ago and is now flying about 350 miles above the Earth, will help shed some light on the mysteries of these space oddities."

"Mission control for the telescope is a small room on the University of California, Berkeley, campus, where about a dozen people with headsets rarely look up from their screens."

"Fiona Harrison, a professor of physics and astronomy at the California Institute of Technology, is the principal scientist for the mission. If there's one word that describes her past few weeks, it's "nail-biting," she says."
