Clementine Mission to Asteroids Clementine Mission to Earth's Moon

Goals: Clementine was to test sensors and spacecraft components under extended exposure to the space environment and to make scientific observations of the Moon and the near-Earth asteroid 1620 Geographos.

Accomplishments: The mission succeeded in its lunar objectives, but a malfunction caused cancellation of the asteroid flyby. Clementine provided our first complete look at the lunar surface, including the poles. And it found evidence suggesting that a crater at the south pole, with a floor that is permanently shielded from the Sun, harbors water ice. The spacecraft obtained multi-spectral imaging of the entire lunar surface, assessed the surface mineralogy, and obtained altimetry from 60°N to 60°S latitude and gravity data for the near side.

Fast Facts
Clementine Facts Clementine was the first U.S. lunar mission in more than two decades.

Clementine was the first spacecraft to photograph the Moon's south polar region.
