In what lunar valley did Apollo 17 land?

Apollo 17 landed in the Taurus-Littrow Valley.

The Lunar Module Challenger touched down there on December 11, 1972, with Eugene Cernan and Harrison Schmitt aboard. Command module pilot Ronald Evans remained in lunar orbit while the landing crew explored the valley and nearby highlands.

Mission planners selected Taurus-Littrow because it offered access to rocks of very different ages. The valley lies at the southeastern edge of Mare Serenitatis, near the rim of a huge impact basin. Samples could help scientists compare ancient lunar crust with younger volcanic material and improve the Moon’s geologic timeline.

Cernan and Schmitt spent roughly 75 hours on the surface, completing three moonwalks and driving the Lunar Roving Vehicle. They returned about 254 pounds of rocks and soil. Fra Mauro was Apollo 14’s region, while Hadley-Apennine was Apollo 15’s site; neither is the Apollo 17 landing valley.
