Nineteen years ago this month, the Clementine mission arrived at the moon. A joint project of NASA and the Department of Defense, Clementine's goals focused on testing lightweight sensors and other deep-space technology demos—but the results reached far beyond that. Besides several technical accomplishments, the mission returned a complete map of the moon, images of the Earth, and confirmed the existance of lunar water ice.

Compared to the instruments on current spacecraft, Clementine's images were relatively small and low resolution. But a search through the raw data reveals some hidden gems. Here are some of my favorite postcards that the intrepid robotic explorer sent home.

The orbiter carried geologic mapping cameras, which let us see some lovely landscapes.
