The landing site selected for Apollo 17 was in the Taurus-Littrow Valley on the eastern rim of Mare Serenitatis. The two primary objectives were obtaining samples of ancient highland material that were older than the Imbrium impact and investigating the possibility of young, explosive volcanism in this region.
The mission lasted 12 days, with a stay on the lunar surface of 75 hours. During this time the crew embarked on three extravehicular activities, which lasted a total of 22 hours. They collected 741 individual rock and soil samples with a total mass of 111 kilograms.
Apollo 17 was launched on December 7th 1972.
