SpaceX failure probe complete; flights to resume Sunday from California

After an exhaustive investigation, SpaceX engineers have identified the most likely cause of the spectacular explosion of a Falcon 9 rocket during a pre-launch test Sept. 1 that destroyed the booster and its $195 million satellite payload, the company announced Monday. SpaceX engineers believe the Cape Canaveral Air Force Station mishap was triggered by the failure of a high-pressure helium tank, one of three used to pressurize the second stage liquid oxygen tank. Putting corrective actions in place, the company said Monday it plans to resume flights with a launch from Vandenberg Air Force Base northwest of Los Angeles on Jan. 8 to boost 10 Iridium NEXT satellite telephone relay stations into orbit.
