Apollo 17 (December 1972)
Gene Cernan and Harrison Schmitt landed in the Taurus-Littrow valley on December 11, 1972. They spent three days on the surface, drove 22 miles in the lunar rover, and collected 243 pounds of rock samples. Cernan was the last human to walk on the Moon.
Apollo 18, 19, and 20 were cancelled. NASA shifted its budget to the Space Shuttle program.
Fifty-four years passed with no human returning to the Moon. The institutional knowledge of how to land humans on another body had to be rebuilt from scratch.
Artemis is the first credible attempt to restore that capability. The May 2026 contracts buy surface infrastructure Apollo never had: a base camp instead of a campsite.
