This photograph shows the first pass of Echo 1, America’s first communications satellite, over the Goldstone Tracking Station managed by NASA’s Jet Propulsion Laboratory, in Pasadena, California, in the early morning of Aug. 12, 1960. The movement of the antenna, star trails, and Echo 1 (the long streak in the middle) are visible in this image.
