On December 7, 1972, NASA launched the Apollo 17 mission, which would become the last manned mission to the Moon in the 20th century. The crew consisted of Commander Eugene Cernan, Lunar Module Pilot Harrison Schmitt, and Command Module Pilot Ronald Evans.

What made this mission particularly significant was the presence of Harrison Schmitt, who was a professional geologist. He was the first scientist-astronaut to land on the Moon, and his expertise greatly enhanced the scientific value of the mission.

During their three days on the lunar surface, Cernan and Schmitt conducted three moonwalks, covering a total distance of about 35 kilometers (22 miles) using the Lunar Roving Vehicle. They collected a record 110 kilograms (243 pounds) of lunar samples, including a deep-drill core sample that provided insights into the Moon's geological history.

One of the most iconic moments of the mission occurred when Cernan, the last man to walk on the Moon, delivered his parting words: "We leave as we came and, God willing, as we shall return: with peace and hope for all mankind."

The Apollo 17 mission marked the end of an era in human spaceflight. It was the longest manned lunar landing flight with the longest total moonwalks and the largest lunar sample return. The mission's success was a testament to the incredible achievements of the Apollo program and the dedication of the thousands of people who worked tirelessly to make it possible.
