Members of the Landsat 7 project, involving scientists from NASA and the U.S. Geological Survey (USGS), announced that, in the course of mapping Antarctica, the team had discovered a giant new crack in one of the world’s largest ice sheets. The team believed that the crack, formed within the past five weeks, would result in the calving of the Pine Island Glacier, creating a major new iceberg within 18 months. NASA had obtained the image from the Landsat 7 satellite, which had passed over Antarctica 16 times daily since its 1999 launch.
