Visiting an Unmanned Pioneer Surveyor 3 landed on the Moon in April 1967. It was visited in November 1969 by Apollo 12 astronaut Alan Bean, who took pieces of the spacecraft back to Earth for analysis. (The Apollo 12 lunar module is visible in the distance.) The retrieved pieces showed evidence of damage by micrometeoroid impacts, demonstrating that small bits of space debris are still colliding with the Moon.
