Earth II (Blue Marble)

Next Generation is a mosaic of satellite data taken mostly from a NASA sensor called the Moderate Resolution Imaging Spectroradiometer (MODIS) that flies board NASA’s Terra and Aqua satellites. The 2002 Blue Marble featured land surfaces, clouds, topography, and city lights at a maximum resolution of 1 kilometer per pixel. (NASA image by Robert Simmon and Reto Stöckli)
