Earth’s Crest Over the Lunar Horizon
This view of the Earth’s crest over the lunar horizon was taken during the Apollo 15 lunar landing mission. Apollo 15 launched from NASA’s Kennedy Space Center on July 26, 1971. Aboard was a crew of three astronauts: David R. Scott, James B. Irwin, and Alfred M. Worden. The primary scientific objectives were to observe the lunar surface, survey and sample material and surface features in a preselected area of the Hadley-Apennine region, setup and activation of surface experiments and conduct in-flight experiments and photographic tasks from lunar orbit.
