Apollo 15 | Simple Site

Earth’s Crest Over the Lunar Horizon

This view of the Earth’s crest over the lunar horizon was taken on July 29, 1971, during the Apollo 15 lunar landing mission. Astronauts David Scott, Alfred Worden, and James Irwin launched from NASA’s Kennedy Space Center in Florida aboard a Saturn V launch vehicle. Designed to explore the Moon over longer periods, greater ranges, and […]
