Why OCO's Launch Failed

NASA Releases Orbiting Carbon Observatory Accident Summary
“A NASA panel that investigated the unsuccessful Feb. 24 launch of the Orbiting Carbon Observatory, or OCO, has completed its report. NASA’s OCO satellite to study atmospheric carbon dioxide launched aboard a Taurus XL rocket from Vandenberg Air Force Base in California on Feb. 24 at 4:55 a.m. EST, but it failed to reach orbit. The Mishap Investigation Board led by Rick Obenschain, deputy director at NASA’s Goddard Space Flight Center in Greenbelt, Md., verified that the Taurus launch vehicle fairing failed to separate upon command. The fairing is a clamshell structure that encapsulates the satellite as it travels through the atmosphere. The failure to shed the fairing mass prevented the satellite from reaching its planned orbit and resulted in its destruction.”
