In the last few years NASA has built and launched two world-class climate satellites, both of which promised new data on the natural and human influences on Earth's changing climate. Neither of them, however, will ever deliver the data that climate scientists so eagerly expected from them. Both spacecraft, in fact, are at the bottom of the ocean, having succumbed to nearly identical rocket mishaps that prevented them from reaching orbit.
The latest incident occurred in the morning hours of March 4, just after the Glory spacecraft lifted off atop a Taurus XL rocket from Vandenberg Air Force Base in California. About three minutes into the flight the protective nose cone, or fairing, enshrouding Glory failed to separate from the rocket as commanded, and the entire assembly came tumbling back to Earth. That is just what happened in February 2009, when NASA's Orbiting Carbon Observatory (OCO) blasted off on board another Taurus XL rocket and came crashing down in the waters off Antarctica.
