Apollo 15 leaves the launch pad at Cape Kennedy, FL

Apollo 15 was the ninth manned mission in the US Apollo program, the fourth to
land on the Moon, and the eighth successful manned mission. It was the first of
what were termed "J missions," long stays on the Moon, with a greater focus on
science than had been possible on previous missions. It was also the first mission
on which the Lunar Roving Vehicle was used.

The mission ended on August 7. At the time, NASA called it the most successful
manned flight ever achieved.

Commander David Scott and Lunar Module Pilot James Irwin spent three days on
the Moon, including 18½ hours outside the spacecraft on lunar extra-vehicular
activity (EVA).
