"NASA's Orbiting Carbon Observatory satellite failed to reach orbit after its 4:55 a.m. EST liftoff Tuesday from California's Vandenberg Air Force Base. Preliminary indications are that the fairing on the Taurus XL launch vehicle failed to separate. The fairing is a clamshell structure that encapsulates the satellite as it travels through the atmosphere. A Mishap Investigation Board will be immediately convened to determine the cause of the launch failure."
"The satellite was launched from Vandenberg Air Force Base in California aboard a Taurus XL rocket, at 1:55 am (0951 GMT), live images on NASA TV showed. It was the first time NASA has used a Taurus rocket, built by Orbital Science Corp., the US space agency said in a statement posted Monday on its website."
