Why Apollo 17 is considered the last moon mission?

 

The Apollo 11 was the first manned mission that successfully landed on the Moon. Manned by three American astronauts, Apollo’s lunar module, the Eagle, landed on the face of the Moon on July 20th, 1969. Neil Armstrong and Edwin Aldrin were the first men to walk on the Moon. Three years later, Apollo 17 was the last Apollo Mission to land men on the Moon. It carried the only trained geologist to walk on the lunar surface – Harrison Schmitt. The Apollo 17 astronauts traversed the greatest distance on the Moon, using the lunar roving vehicle. They also returned the greatest amount of samples of rock and soil. The last human being to walk on the Moon was the Commander of Apollo 17, Eugene Cernan. No humans have visited the Moon since December 14th 1972.
