Which Apollo mission was the last one in NASA's Apollo program?

Apollo 17 was the last mission in NASA's Apollo program because it was the sixth and final successful lunar landing mission. Launched on December 7, 1972, the mission aimed to explore the Taurus-Littrow region of the Moon's surface. Astronauts Eugene Cernan, Harrison Schmitt, and Ronald Evans were part of the crew, with Cernan and Schmitt being the last two humans to walk on the lunar surface to date. This mission concluded the Apollo program as subsequent missions were canceled due to budget constraints and shifting priorities within NASA, marking the end of human exploration on the Moon for the foreseeable future.
