WASHINGTON (NASA PR) — NASA’s Commercial Crew Program and the agency’s industry partners completed 23 agreement and contract milestones in 2014 and participated in thousands of hours of technical review sessions. The sessions focused on creating a new generation of safe, reliable and cost-effective crew space transportation systems to low-Earth orbit destinations.

SPARKS, Nev., Dec. 2, 2014 (SNC PR) – Sierra Nevada Corporation (SNC) announces the successful completion of a major milestone relating to the Reaction Control System (RCS) propulsion risk reduction for the Dream Chaser®  Space System, known as Milestone 15a. The achievement further matures the design toward Critical Design Review (CDR) and positions SNC one step closer to concluding all milestones laid out in NASA’s Commercial Crew Integrated Capability (CCiCap) agreement. To date, SNC has received 96 percent of the total award value of the CCiCap agreement, having successfully completed 12 of 13 milestones.

Sources report that Sierra Nevada Corporation (SNC) has shut down its rocket engine test facility in Poway, Calif., where the company has tested propulsion systems for the Dream Chaser space shuttle and Virgin Galactic’s SpaceShipTwo suborbital vehicle.

The company laid off more than 100 employees last week, including around 70 in Poway with the rest in Colorado, sources report.

Sierra Nevada lost out on two big contracts this year. In May, Virgin Galactic announced it was switching from SNC’s rubber hybrid to a nylon hybrid engine developed by Scaled Composites to power SpaceShipTwo. The rubber hybrid had been tested down in Poway.

In September, SNC lost out on the next round of NASA Commercial Crew Program contracts when the space agency selected Boeing and SpaceX to develop vehicles to fly to the International Space Station. SNC’s Dream Chaser shuttle was not selected.

SNC has appealed the decision. The Government Accountability Office has until early January to make a decision on the appeal.

NASA Commercial Crew Partners Continue System Advancements

WASHINGTON (NASA PR) — NASA’s industry partners continue to complete development milestones under agreements with the agency’s Commercial Crew Program. The work performed by Blue Origin, Boeing, Sierra Nevada Corporation and SpaceX during partnership and contract initiatives are leading a new generation of safe, reliable and cost-effective crew space transportation systems to low-Earth orbit destinations.

Blue Origin conducted an interim design review of the subsystems in development for its Space Vehicle spacecraft designed to carry people into low-Earth orbit. The September review was performed under an unfunded Commercial Crew Development Round 2 (CCDev2) agreement with NASA. In October, NASA and Blue Origin agreed to add three additional unfunded milestones to the agreement to continue the development work and partnership. Those milestones will include further testing of Blue Origin’s propellant tank, BE-3 engine and pusher escape system.

The Wall Street Journal has a good piece on all the problems Scaled Composites and Virgin Galactic have had with SpaceShipTwo and WhiteKnightTwo over the years. It pretty confirms everything I’ve been writing for the last few years, adding some interesting details but getting a few of them wrong.

There were a number of interesting elements here:

The article claims that Sierra Nevada Corporation was brought in by Scaled Composites to develop SpaceShipTwo’s engine  in 2009. That’s not accurate.

SPARKS, Nev. (Oct. 23, 2014) – Sierra Nevada Corporation’s (SNC) Space Systems presents the Dream Chaser Science Mission Mock-Up at the American Society for Gravitational and Space Research (ASGSR) conference in Pasadena, California, through Oct. 26. In addition to the primary function of transporting crew and cargo to and from low-Earth orbit (LEO), SNC’s Dream Chaser® program team has been developing a science mission variant which leverages the inherent capabilities of the vehicle to offer a free-flying microgravity science laboratory.

Judge Knocks Down SNC’s Motion for Commercial Crew Work Stoppage

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.

Court Holds Initial Hearing on Sierra Nevada’s Effort to Reimpose Commercial Crew Stop Work Order

U.S. Court of Federal Claims Judge Marian Blank Horn heard initial arguments on Friday on a motion by Sierra Nevada Corporation to stop Boeing and SpaceX from continuing work on recently awarded NASA commercial crew contracts pending an appeal of the awards.

The judge did not rule on the motion, but set an additional hearing on Tuesday to hear further arguments, according to press reports.

Sierra Nevada has appealed the awards NASA has made to Boeing and SpaceX citing alleged irregularities in the process. NASA’s decisions left Sierra Nevada without additional government funding to complete its Dream Chaser shuttle.

NASA initially ordered Boeing and SpaceX to stop work under the contracts, but the space agency later reversed its decision. Sierra Nevada is seeking to reinstate the stop work order.

The Government Accountability Office has until early January to rule on Sierra Nevada’s protest of NASA’s commercial crew awards.

Sierra Nevada Files Suit to Reinstate Hold on Commercial Crew Work

Space News reports that Sierra Nevada Corporation has filed suit to stop Boeing and SpaceX from continuing commercial crew work while the company’s appeal of the awards to the two companies is pending.

In filings with the U.S. Court of Federal Claims in Washington, Sierra Nevada filed requests for both a temporary restraining order and a preliminary injunction to overturn a NASA decision Oct. 9 lifting an order stopping work on Commercial Crew Transportation Capability (CCtCap) contracts awarded Sept. 16 to Boeing and Space Exploration Technologies Corp.

NASA had issued a stop-work order shortly after Sierra Nevada filed a protest regarding the CCtCap awards with the U.S. Government Accountability Office Sept. 26. On Oct. 9, NASA lifted the order, citing “statutory authority available to it” in order to keep the program on schedule.

NASA justified the decision by warning that any delay in carrying out the contracts “poses risks” to the international space station crew and could jeopardize operations of the station. “NASA has determined that it best serves the United States to continue performance of the CCtCap contracts,” the agency said in a statement posted on the commercial crew program website.

A hearing is scheduled for Friday morning.
