NASA asked the public to vote for their favorite satellite image from the series created by the U.S. Geological Survey, “Earth as Art,” and posted the five most favorited images about a month ago. “Earth as Art” is composed of images taken by satellites part of the Landsat Program, which is managed by both NASA and the U.S. Geological Survey.
