NASA has launched a new mission to unravel some of the universe’s most intense mysteries. Scientists sent GLAST — the Gamma-ray Large Area Space Telescope — into orbit from the Kennedy Space Center. A Delta 2 rocket catapulted the high-tech scope to its destination Wednesday in a meager 90 minutes. Now, the effort to answer centuries-old questions begins. The $690 million telescope will pick up the puzzle left behind by its predecessor — the Energetic Gamma-Ray Experiment Telescope, or EGRET — which was put to rest eight years ago.
