NASA's Operation IceBridge is a six-year mission to survey land and sea ice at the poles. The program's DC-8 research plane, loaded with remote-sensing equipment, captured spectacular images of Antarctica's mountains and glaciers in October 2012, the first half of this year's campaign. Combining new measurements with previously gathered data gives researchers a more detailed view of ice dynamics. The resulting information will help improve computer models that predict how ice sheets change over time.
