This week a European Earth-observing satellite confirmed that a large iceberg broke off of Pine Island Glacier, one of Antarctica's largest and fastest moving ice streams. The rift that led to the new iceberg was discovered in October 2011 during NASA's Operation IceBridge flights over the continent.
