Thales Alenia Space and Gazprom Space Systems are confident that efforts to recover Russia's Yamal 402 Ku-band commercial telecom satellite will succeed, but it remains unclear how much of the spacecraft's 15-year service life will be lost. A premature shutdown of the Briz M upper stage on its International Launch Services (ILS) launch vehicle Dec. 9 left Yamal 402 in the wrong orbit, and controllers are using its onboard station-keeping/attitude control propellant to adjust it.

Odds of losing climate satellite ran as high as 50%.

NASA will spend the next 16 months nailing down exactly how its three commercial crew contractors plan to meet the agency's detailed requirements for flying astronauts to the International Space Station and bringing them back to Earth in one piece. The agency will spend almost $30 million with the three companies—Boeing, Sierra Nevada Corp. and SpaceX—on the first phase of the “certification products contracts” (CPC) that will bring the vehicle designs they are developing into line with NASA's formal safety requirements.

A probe into an upper-stage low-thrust anomaly during an October GPS launch has verified that a leak occurred in the RL10B-2 engine. But, a root cause continues to elude investigators, and satellite owners are proceeding with Evolved Expendable Launch Vehicle (EELV) missions only if they are willing to accept any extra risk resulting from the unknowns surrounding the incident.

They could not have timed it better: One day after France launched its second high-resolution Pleiades satellite, shareholders of U.S. commercial imagery provider GeoEye approved a buyout by the company's chief U.S. competitor that will leave Longmont, Colo.-based DigitalGlobe operating the largest fleet of high-resolution optical Earth-imaging satellites.

As Hurricane Sandy wound its way north along the Atlantic Coast in late October, the storm appeared to be on a track to head harmlessly out to sea. But data from the National Oceanic and Atmospheric Administration's (NOAA) polar orbiting weather satellites indicated that the deadly storm would take a sharp left turn and hit some of the most densely populated regions of the U.S., providing days of warning.
