SAN FRANCISCO — The first ever global map of Mercury was released here Tuesday at the American Geophysical Union meeting. The map combines new observations from the Messenger spacecraft with earlier images captured by Mariner 10 in the 1970s.
The U.S. Geological Survey built the map from 917 images of variable resolution and lighting conditions, but sophisticated software was able to match up planetary features from different images to create the near seamless mosaic.
