While many artists and photographs aim to get up close-up images of the national parks, NASA is able to offer a unique perspective by capturing national parks from space. In honor of the recent centennial of the U.S. National Park Service, NASA's Earth Observatory compiled this collection of "NASA's best images of national parks and other federal lands, along with stories of earth science in those parks." When visitors select an image, they can view a short essay and links that provide context for the Image of the Day. For example, one image in this collection features a photograph of Crater Lake taken by an International Space Station (ISS) astronaut, accompanied by an essay with a number of embedded links to resources from the U.S. Geological Survey that provide insight into Crater Lake and Wizard Island. Another image portrays North Cascades National Park as captured by Operational Land Imager (OLI) on the Landsat 8 satellite. This satellite image is accompanied by a number of photographs of, as well as information about, the North Cascades.
