This comes just two years after a similar failure mode occurred for the Orbiting Carbon Observatory (OCO)—also launched on a Taurus XL. There was an extensive investigation following that February 2009 failure; the fairing underwent a redesign of its separation system and had been cleared for use for the Glory mission. A mishap investigation board has been...
