NASA Views Laser Landscapes of Helheim Glacier

The video explores the changes in Greenland's glaciers, focusing on the Helheim Glacier. Over two decades, NASA missions have used laser altimeters and other advanced instruments to map and analyze the glacier's surface, revealing significant retreat and thinning. The video highlights the importance of continuous monitoring through initiatives like Operation Icebridge and future satellite missions to understand and respond to climate change impacts on glaciers.
