- Abstract
- This mosaic shows Mercury's surface in "enhanced color," a term used to describe a color scheme created to emphasize color differences on Mercury's surface. This is not what Mercury would look like to the human eye, but rather by applying mathematical analysis to MESSENGER images, color differences on Mercury's surface can be accentuated beyond those visible to a person. This view uses a global mosaic with 430, 750, and 1000 nm bands and places the second principal component, the first principal component, and the 430/1000 ratio in the red, green, and blue channels respectively. This mosaic contains data acquired by the MErcury Surface, Space ENvironment, GEochemistry and Ranging (MESSENGER) Mercury Dual Imaging System (MDIS) instrument.
