YAHOO.COM - The U.S. Air Force's launch of the next secret mission by its unmanned X-37B space plane has been officially delayed to mid-November.

The upcoming X -37B space plane mystery mission, also known as Orbital Test Vehicle-3 (OTV-3), was slated to blast off atop an Atlas 5 rocket on Oct. 25 from Space Launch Complex 41 at Cape Canaveral Air Force Station in Florida. The liftoff is now scheduled for Nov. 13, according to ULA.

The delay was announced Saturday (Oct. 20) in an update by the mission's launch provider, United Launch Alliance (ULA). ULA officials said an engine glitch during an Oct. 5 launch of a Delta 4 rocket that successfully orbited a Global Positioning System 2F-3 satellite.

An unexpected lower than normal chamber pressure was observed on the booster's RL10 upper stage engine. The onboard inertial guidance and flight control systems compensated for the lower thrust, with the Delta second stage placing the spacecraft into the proper orbit. click here to read more
