Ice, Cloud and land Elevation Satellite 2
The Ice, Cloud and Land Elevation Satellite 2 (ICESat-2) is part of NASA?s Earth Observing System. It observes ice sheet elevation, sea ice thickness, land topography, vegetation characteristics and clouds. The satellite was launched in 2018 for a three-year mission.
The ICESat-2 has enabled the American space agency to precisely map the subglacial lakes in Antarctica. It measures the height of the ice surface, which, despite its enormous thickness, rises or falls as lakes fill or empty under the ice sheet. The satellite assesses how the hidden plumbing system influences the speed at which ice slips into the Southern Ocean.
