Soaring, snow-capped peaks and ridges of the eastern Himalaya Mountains create an
irregular white-on-red patchwork between major rivers in southwestern China. The
Himalaya are made up of three parallel mountain ranges that together extend more
than 2,900 kilometers.
This scene was acquired by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER), flying aboard NASA’s
Terra satellite, on February 27, 2002. This false-color composite image was created by
combining near-infrared, red, and green wavelengths (ASTER bands 3, 2, and 1, respectively).

The braided streams of the Betsiboka Estuary have largely returned to their normal size, leaving puddles of blue and green water to show the extent of earlier flooding. Tropical Cyclone Gafilo moved across Madagascar on March 7 and 8, dumping heavy rain in its path. As time passed, the waters eventually flowed down the rivers to the coast, flooding the low-lying land in the west. The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on the Terra satellite captured this image of the estuary on March 20, 2004. The false-color image uses green, red, and near-infrared light (ASTER bands 3, 2, 1) so that the main river is green, other water is blue, and vegetation is red.
