Apollo 17 Lunar Roving Vehicle

The Apollo 17 Lunar Roving Vehicle carried astronauts Eugene Cernan and Harrison Schmitt — the only professional geologist to walk on the Moon — across the Taurus-Littrow valley. They drove 35.9 km over three EVAs, venturing 7.6 km from the Lunar Module at the farthest point. Schmitt discovered orange soil near Shorty Crater, later identified as 3.7-billion-year-old volcanic glass beads, providing critical evidence of ancient lunar volcanism. The mission collected 110.5 kg of samples, the most of any Apollo mission.
