ULA Erring On The Side Of Caution... X-37B Orbital Test Vehicle Launch Postponed


[SatNews November 4, 2012] The Company’s leadership and the Air Force have decided to postpone the launch two weeks to allow for additional flight data anomaly investigation activities and a thorough crossover assessment.

The launch of an Atlas V carrying the third X-37B Orbital Test Vehicle (OTV-3) payload for the U.S. Air Force is rescheduled for November 27, pending confirmation from the 45th Space Wing regarding the revised range reservation.

Although the team investigating the lower than normal upper-stage engine chamber pressure from the recent Global Positioning System (GPS) IIF-3 launch has been making good progress reviewing and analyzing the data, ULA leadership and the Air Force have decided to postpone the launch two weeks to allow for additional flight data anomaly investigation activities and a thorough crossover assessment for the X-37B OTV launch vehicle to be completed. 

This flight data anomaly investigation is being conducted with investigative processes that have been refined over decades of launch experience and include extensive reconstruction of the flight data with analytical models, as well as detailed inspections of several engines. The OTV-3 launch will be the third launch of the Air Force's test vehicle.
