In late 2017, a specially modified airplane contracted by NASA crisscrossed Antarctica, mapping the ice below and filling in a data gap left by a now-defunct NASA satellite called ICESat, which measured the elevation of the ice surface using a laser. Operation IceBridge flights are bridging the gap between ICESat and its successor, ICESat-2.

In January, researchers went for a more than 750-kilometer drive around the South Pole. The team followed the arc of the 88th parallel for a quarter of its distance ringing the South Pole. Their cargo was a sensitive GPS unit to record the exact elevation of the ice sheet they drove over. The effort is in support of NASA's ICESat-2 satellite, a mission devoted to measuring ice levels around the world, particularly in the polar regions.
