NASA’s Landsat satellite looks for a cloud-free view

For decades, Landsat satellites have documented the desiccation of the Aral Sea in Central Asia. Once one of the largest seas in the world, it shrunk to a tenth of its original volume after Russia diverted its feeder rivers in the 1960s. Scientists studying the Aral Sea’s changing ecology and retreating shoreline have looked to Landsat — and a new feature of the Landsat Data Continuity Mission will help ensure they get a clear, cloud-free view.
