NASA has granted the Science Applications International Corp. (SAIC) of San Diego a pair of six-month contract extensions valued at $32.9 million for continued safety and mission assurance and technical support services at the Johnson Space Center in Houston. The agreement provides support for the International Space Station, Orion/Multi-Purpose Crew Vehicle and yet-to-be-named programs managed from Houston by the space agency, according to a Jan. 26 announcement. The extension period begins May 1.

COLLISION: The U.S. Coast Guard is investigating the Jan. 26 collision of a barge carrying Atlas V rocket stages with a bridge over the Tennessee river that caused part of the bridge to collapse. The 312-ft. vessel, which is owned and operated by Foss Marine, was carrying an Atlas V booster and Centaur upper stage for the U.S. Air Force’s AEHF-2 mission scheduled to launch in April, along with an interstage adapter for NASA’s Radiation Belt Storm Probes mission slated to launch in August.

The launch of a telecommunications satellite has been postponed due to an unspecified technical problem.

DATA DUMP: The Japan Aerospace Exploration Agency (JAXA) plans to distribute some of the minute samples its Hayabusa probe returned from the asteroid Itakowa. The spacecraft, which imaged its shadow against the type-S asteroid as it approached in the fall of 2005, returned more than 1,000 asteroid particles measuring about 10 micrometers (0.0004 in.), despite control problems at its target. The tiny samples have been analyzed by Japanese scientists, and now will be available in a peer-reviewed opportunity.

NASA does not have adequate plans to deal with the significant likelihood that the International Space Station (ISS) may have to be abandoned at some point during the remainder of this decade, nor is it addressing safety issues with its plan to use commercial vehicles to deliver crews to the orbiting outpost, the agency’s outside safety review organization has concluded. In its 2011 annual report, the Aerospace Safety Advisory Panel (ASAP) sees “more than an outside possibility” that the ISS will suffer a loss-of-mission event during its projected lifetime.

LONDON — China’s plan to launch 12 more Compass navigation satellites and inaugurate their operational use this year is only one of several key satellite activities planned for 2012.

Boeing says the big news in pulse manufacturing is not limited to production ramp-ups in its 737 factories in Washington. It also is making news in manufacturing satellites on an assembly line in El Segundo, Calif. Boeing Satellite Systems has four identical Global Positioning System IIF satellites pulsing through an assembly line with 13 distinct manufacturing “post” positions as part of a U.S. Air Force contract with a total value of $1.35 billion.

Boeing CEO James McNerney predicts that more of the company’s military sales will originate overseas, as the U.S. defense budget comes under pressure. McNerney told analysts Jan. 25 that with “tough U.S. defense budgets,” the company sees “significant upside in the international defense market” for Boeing Defense, Space and Security (BDS). He forecasts that as much as 25-30% of revenues for the unit could come from international sales “in the next few years.”
