This is the last year for Operation IceBridge, NASA’s most comprehensive airborne survey of ice change. Since the launch of its first Arctic campaign in spring 2009, IceBridge has enabled discoveries ranging from water aquifers hidden within snow in southeast Greenland, to the first map indicating where Now, for the first time since its inaugural flights a decade ago, while IceBridge is mapping Greenland’s ice from the air, one of NASA’s newest satellite missions, the Ice, Cloud and land Elevation Satellite-2 (ICESat-2), is simultaneously mapping that ice from space.
