More than 50 years ago, on Dec. 11, 1972, two US astronauts from the Apollo 17 lunar landing mission, Gene Cernan and Harrison Schmitt, became the most recent humans to step onto the gray, dusty, and rocky surface of the Moon.
Today, NASA (the National Aeronautics and Space Administration) is partnering with international space agencies and commercial enterprises to make the 238,855-mile (384,400-kilometer) return trip a reality in the 2020s.
They’re calling it the Artemis program.
