Lunar Temperature vs. Water Signal (Comparison)

Image Credit: NASA/JPL-Caltech/University of Maryland

Original Caption: This chart highlights observations from NASA's Deep Impact mission of the northern polar regions of the moon acquired on June 9, 2009. The image at left is a map of the moon taken by the U.S. Clementine satellite -- the rest of the images are different representations of Deep Impact data, including measurements of brightness, temperature, and strength of a signature for water and hydroxyl molecules. The water signature varies significantly across the lunar surface; the strength of the signature is not correlated with terrain type but is highly dependent on temperature ...
