- The last time a person visited the moon was in December 1972, during NASA's Apollo 17 mission.
- Astronauts say the reasons why are budgetary and political, not scientific or technical.
- NASA could land people on the moon again by 2026 at the earliest. Now a US lander is on the moon again.
Landing 12 people on the moon remains one of NASA's greatest achievements, if not the greatest.
