Orbiting Carbon Observatory (OCO)

Status: Other
Mission Category: Earth System Science Pathfinder Program
Launch Date: February 24, 2009
Launch Location: Vandenberg Air Force Base, CA
Actual Completion Date: February 24, 2009

The Orbiting Carbon Observatory (OCO) was designed to provide space-based global measurements of atmospheric carbon dioxide (CO2) with the precision and resolution needed to identify and characterize the processes that regulate this important greenhouse gas. With its three high-resolution grating spectrometers, data collected by OCO could be combined with meteorological observations and ground-based CO2 measurement to help characterize CO2 sources and sinks on regional scales at monthly intervals for 2 years.

Shortly after launch on February 24, 2009, the fairing-a clamshell structure that encapsulates the satellite-on the Taurus XL launch vehicle carrying OCO failed to separate and OCO did not reach orbit.
