- This mosaic picture of the Moon was compiled from 18 images taken
- with a green filter by Galileo's imaging system during the
- spacecraft's flyby on December 7, 1992, some 11 hours before its
- Earth flyby at 1509 UTC (7:09 a.m. Pacific Standard Time)
- December 8. The north polar region is near the top part of the
- mosaic, which also shows Mare Imbrium, the dark area on the left;
- Mare Serenitatis at center; and Mare Crisium, the circular dark
- area to the right. Bright crater rim and ray deposits are from
- Copernicus, an impact crater 96 kilometers (60 miles) in
- diameter. Computer processing has exaggerated the brightness of
- poorly illuminated features near the day/night terminator in the
- polar regions, giving a false impression of high reflectivity
- there. The digital image processing was done by DLR, the German
- aerospace research establishment near Munich, an international
- collaborator in the Galileo mission. The Galileo project, whose
- primary mission is the exploration of the Jupiter system in 1995-
- 97, is managed for NASA's Office of Space Science and
- Applications by the Jet Propulsion Laboratory.
