OCO Fails to Reach Orbit

NASA's Orbiting Carbon Observatory satellite failed to reach orbit after its 4:55 a.m. EST liftoff Feb. 24 from California's Vandenberg Air Force Base.

Preliminary indications are that the fairing on the Taurus XL launch vehicle failed to separate. The fairing is a clamshell structure that encapsulates the satellite as it travels through the atmosphere.

The spacecraft did not reach orbit and likely landed in the ocean near Antarctica, said John Brunschwyler, the program manager for the Taurus XL.

A Mishap Investigation Board is to determine the cause of the launch failure.
