iss073e0818427 (Oct. 2, 2025) --- The Bassac River surrounds Cù Lao Dung, a river islet district in southern Vietnam, before emptying into the South China Sea. The river’s brown waters at its mouth result from massive amounts of silt, clay, and organic matter carried from upstream regions of the Mekong River Basin, combined with tidal forces from the sea that stir up sediment. This photograph was taken from the International Space Station as it orbited 260 miles above Earth.
