The first photo of the United States by NASA satellite
In 1974, NASA published their first satellite photo of the contiguous United States by stitching together a bunch of individual images.
A giant photo map of the contiguous 48 states of the United States, the first ever assembled from satellite images, completed for NASA by the U.S. Department of Agriculture Soil Conservation Service Cartographic Division. The map is 10 by 16 feet, is composed of 595 cloud-free black-and-white images returned from NASA’s first Earth Resources Technology Satellite (ERTS-1). The images were all taken at the same altitude (912 kilometers: 560 miles) and the same lighting angle. The images were produced by the spacecraft’s Multi-spectral Scanner System (MSS) in Band 5, or the red portion of the visible spectrum, during the period July 25 to October 31, 1972.
