WASHINGTON, Nov. 5 (Xinhua) -- U.S. space company Orbital Sciences Corp. said Wednesday that an engine failure is the likely cause of last week's Antares rocket launch explosion that destroyed an unmanned Cygnus spacecraft loaded with supplies for the International Space Station (ISS).

"While the work of the AIB (Accident Investigation Board) continues, preliminary evidence and analysis conducted to date points to a probable turbopump-related failure in one of the two Aerojet Rocketdyne AJ26 stage one main engines," the Virginia- based company said in a statement.
