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.

The history of the East Antarctic Ice Sheet is written in stones along the Transantarctic Mountains. Over the past two years, researchers ventured to remote areas along the mountain range to decipher how high ancient glaciers reached, by studying the rocks they left behind. By measuring the amount of cosmic radiation the rocks have been exposed to, the research team can map out the reach of ancient glaciers at different points in the past.
