Figuring Out What Really Happened to Glory and OCO

After failed space flights, NASA investigation leads to Portland, The Oregonian

"Twice in the past decade, NASA launched unmanned spacecraft ferrying advanced satellites into Earth's orbit as part of a mission that could offer researchers an unprecedented new source of data on climate change. But the satellites failed to deploy and, within minutes, NASA's $550 million investment and years of work vaporized in fiery balls of space junk. NASA has been investigating ever since. Now the inquiry has led to a nondescript industrial building in Northeast Portland, where a company called Sapa Extrusions acknowledges it has been dealing in bad aluminum and bad faith for as long as two decades."

NASA Creates Glory Satellite Mishap Investigation Board, earlier post

"NASA's Glory mission ended Friday after the spacecraft failed to reach orbit following its launch from Vandenberg Air Force Base in California. NASA has begun the process of creating a Mishap Investigation Board to evaluate the cause of the failure. Telemetry indicated the fairing, a protective shell atop the satellite's Taurus XL rocket, did not separate as expected. The launch proceeded as planned from its liftoff at 5:09 a.m. EST through the ignition of the Taurus XL's second stage. However, the fairing failure occurred during the second stage engine burn. It is likely the spacecraft fell into the South Pacific, although the exact location is not yet known. NASA's previous launch attempt of an Earth science spacecraft, the Orbiting Carbon Observatory onboard a Taurus XL on Feb. 24, 2009, also failed to reach orbit when the fairing did not separate."
