Orbiting Carbon Observatory

The Orbiting Carbon Observatory (OCO) was a failed NASA satellite mission intended to provide global space-based observations of atmospheric carbon dioxide (CO2). The original spacecraft was lost in a launch failure on 24 February 2009, when the payload fairing of the Taurus rocket which was carrying it failed to separate during ascent.[3] The added mass of the fairing prevented the satellite from reaching orbit.[4] It subsequently re-entered the atmosphere and crashed into the Indian Ocean near Antarctica.[5][6] The replacement satellite, Orbiting Carbon Observatory-2, was launched 2 July 2014 aboard a Delta II rocket.[7][8] The Orbiting Carbon Observatory-3, a stand-alone payload built from the spare OCO-2 flight instrument, was installed on the International Space Station's Kibō Exposed Facility in May 2019.[9]
