A Federal Court of Claims judge has rejected a motion by the Sierra Nevada Corporation to re-impose a stop-work order on NASA’s commercial crew program, according to press reports. It is not immediately clear why Judge Marian Blank Horn rejected the motion.

NASA has initially ordered Boeing and SpaceX to stop work on commercial crew contracts the agency awarded the two companies while the Government Accountability Office (GAO) reviewed an appeal by Sierra Nevada, which did not receive an award.

However, NASA later lifted the order, saying any delay would imperil efforts to keep the commercial crew program on schedule and meet its commitments for operating the International Space Station. Sierra Nevada subsequently appealed that decision.

The GAO has until Jan. 5 to rule on Sierra Nevada’s appeal of the commercial crew awards.
