KENNEDY SPACE CENTER, FLA. --Racing into the night sky atop columns of fire, space shuttle Endeavour on mission STS-123 shows blue cones of light beneath its engines. The shock or mach diamonds are a formation of shock waves in the exhaust plume of an aerospace propulsion system. Liftoff was on time at 2:28 a.m. EDT. The crew will make a record-breaking 16-day mission to the International Space Station and deliver the first section of the Japan Aerospace Exploration Agency's Kibo laboratory and the Canadian Space Agency's two-armed robotic system, Dextre.
