NASA successfully launched its first spacecraft dedicated to studying atmospheric carbon dioxide at 2:56 a.m. PDT (5:56 a.m. EDT) Wednesday.
The Orbiting Carbon Observatory-2 (OCO-2) raced skyward from Vandenberg Air Force Base, California, on a United Launch Alliance Delta II rocket. Approximately 56 minutes after the launch, the observatory separated from the rocket’s second stage into an initial 429-mile (690-kilometer) orbit. The spacecraft then performed a series of activation procedures, established communications with ground controllers and unfurled its twin sets of solar arrays. Initial telemetry shows the spacecraft is in excellent condition.
OCO-2 soon will begin a minimum two-year mission to locate Earth’s sources of and storage places for atmospheric carbon dioxide, the leading human-produced greenhouse gas responsible for warming our world and a critical component of the planet’s carbon cycle.
