Schmitt is the first scientist and twelfth and last person to step on the Moon
Joining NASA in its first astronaut class to include scientist-astronauts in June 1965, geologist Harrison H. "Jack" Schmitt was on the backup crew for Apollo 15. In August 1971, he was assigned as the Lunar Module Pilot for the last Apollo mission to the Moon, Apollo 17.

The Moon on the Path to Mars
Humans landing on the Moon still resonates as an inspiration and hope for future exploration. 44 years after the last Apollo mission, the Moon is now seen as a frontier for resource utilization and international collaboration by the emerging commercial industry and space agencies around the globe.
