The Apollo 15 mission launched from Kennedy Space Center on 26 July 1971 with astronauts David R. Scott, Alfred M. Worden, and James B. Irwin on board. Scott and Irwin took their first steps onto the lunar surface on 30 July with Scott remarking, “As I stand out here in the wonders of the unknown…I sort of realize there’s a fundamental truth to our nature. Man must explore. And this is exploration at its greatest.”
