Schmitt, an experienced geologist, is the only scientist to have walked on the Moon. He and Eugene Cernan explored the surface with a lunar rover, collecting rock samples, taking photographs and setting up science experiments.
Schmitt was also involved in the scientific aspects of the other Apollo landings and instructed crew members in lunar geology and feature recognition.

In 1972, Apollo 17's Harrison Schmitt, the only scientist to walk on the Moon, and his fellow astronaut Eugene Cernan discovered orange volcanic soil. At first, it was thought that this was evidence of recent lunar volcanism.

Harrison Hagan "Jack" Schmitt (born July 3, 1935) is an American geologist, a retired NASA astronaut, university professor, and a former U.S. senator from New Mexico.
Schmitt was the first of NASA's first scientist astronaut group to fly in space, on the Apollo 17 mission in December 1972. He was the twelfth and last man to set foot on the Moon. As of 2013[update] he is the only professional geologist to visit the Moon. He was influential with the community of lunar geologists supporting the Apollo program, and used this to improve the geological training of the pilot-astronauts who landed on the Moon.
Schmitt resigned from NASA in August 1975 to run for election to the United States Senate from New Mexico in the 1976 election. He ran as a Republican and defeated the two-term incumbent. He was defeated for a second term in 1982.
