A camera on the International Space Station captured this Oct. 2, 2025, photo of the Bassac River in Cù Lao Dung, a river islet district in southern Vietnam. The Bassac River surrounds the district 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 as the space station orbited 260 miles above Earth.

国际空间站上的一台相机于2025年10月2日拍摄了这张越南南部九龙江三角洲岣崂榕县（Cù Lao Dung）巴萨河的照片。巴萨河环绕该河中岛区后汇入南海。河口呈现褐色的河水，源于大量来自湄公河流域上游的淤泥、黏土和有机物质，同时叠加海洋潮汐作用搅动沉积物所致。这张照片拍摄时，国际空间站正以距地约260英里的高度环绕地球运行。
