NASA | Operación IceBridge: Explorando la Antártida

NASA's Antarctic missions focus on studying changes in the ice sheet and sea ice. Using a DC 8 aircraft, the missions explore remote areas, employing instruments like lasers and radars to measure ice thickness and changes. The missions have identified significant changes in glaciers, such as the Pine Island Glacier, and continue to monitor these areas to understand ice flow evolution.
