From: baalke@kelvin.jpl.nasa.gov (Ron Baalke) Newsgroups: comp.graphics,comp.misc Subject: Galileo GIF Images Available Date: 28 Dec 92 17:23:00 GMT Organization: Jet Propulsion Laboratory ======================= GALILEO GIF IMAGES December 28, 1992 ======================= Five Galileo images released at last week's press conference are now available in GIF format (GIF89a). The images were scanned in from photographs and are not the raw data. Caption files accompanying each image are attached below, and the caption files are also embedded in the image. Make sure you are in binary mode when downloading the images, and in ascii mode when downloading the caption files. The Galileo images are available using anonymous ftp to: ftp: ames.arc.nasa.gov (128.102.18.3) user: anonymous cd: pub/SPACE/GIF files: andes.gif - False color mosaic of the Andes Mountains andes.txt - caption file earthmo2.gif - Color image of the Earth and Moon earthmo2.txt - caption file mideast.gif - Color image of the Middle East including Somalia mideast.txt - caption file moonfals.gif - False color mosaic of the northern regions of the Moon moonfals.txt - caption file moongrid.gif - Gray scale Moon image with overlayed grid moongrid.txt - caption file ----------------------------------------------------------------------------- andes.txt PUBLIC INFORMATION OFFICE JET PROPULSION LABORATORY CALIFORNIA INSTITUTE OF TECHNOLOGY NATIONAL AERONAUTICS AND SPACE ADMINISTRATION PASADENA, CALIF. 91109. TELEPHONE (818) 354-5011 PHOTO CAPTION GALILEO December 22, 1992 P-41493 TOP GLL/EM21 This false-color mosaic of the central part of the Andes mountains of South America (70W, 19S) is made up of 42 images taken by the Galileo spacecraft from an altitude of about 25,000 kilometers (15,000 miles). The combination of visible and near- infrared filters (green, 0.76 micron and 1.0 micron) was chosen for this picture to separate regions with distinct vegetation and soil types. The mosaic shows the area where Chile, Peru, and Bolivia meet. North is to the left, and the Pacific coast (bottom of picture) is in the foreground. Lakes Titicaca and Poopo are nearly black patches left to right; a large light blue area below and left of Lake Poopo is Salar de Uyuni, a dry salt lake some 120 kilometers (75 miles) across. These lakes lie in the Altiplano, a region between the western and eastern Andes, which are covered by clouds. The water/ice content of the clouds is indicated by their shade of pink. The vegetated Gran Chaco plains east of the Andes are pale green (top of picture). Light blue patches in the mountains to the north (left) are glaciers.

TELEPHONE (818) 354-5011 PHOTO CAPTION GALILEO December 22, 1992 P-41508 TOP GLL/EM23 Eight days after its encounter with the Earth, the Galileo spacecraft was able to look back and capture this view of the Moon in orbit about the Earth, taken from a distance of about 6.2 million kilometers (3.9 million miles), on December 16. The picture was constructed from images take through the violet, red, and 1.0-micron infrared filters. The Moon is in the foreground, moving from left to right. The brightly-colored Earth contrasts strongly with the Moon, which reflects only about one-third as much sunlight as Earth. Contrast and color have been computer- enhanced for both objects to improve visibility. Antarctica is visible through clouds (bottom). The Moon's far side is seen; the shadowy indentation in the dawn terminator is the south- Pole/Aitken Basin, one of the largest and oldest lunar impact features, extensively studied from Galileo during the first Earth flyby in December 1990.

TELEPHONE (818) 354-5011 PHOTO CAPTION GALILEO December 22, 1992 P-41474 TOP GLL/EM22 This color image of North-East Africa and Arabia was taken from an altitude of about 500,000 kilometers (300,000 miles) by the Galileo spacecraft on December 9, 1992, as it left the Earth enroute to Jupiter. Most of Egypt (center left) including the Nile Valley, the Red Sea (slightly above center), Israel, Jordan, and the Arabian peninsula are cloud-free. In the center, below the cloud on the coast, is Khartoum, at the confluence of the Blue Nile and the White Nile. Somalia (lower right) is partly cloud- covered.

TELEPHONE (818) 354-5011 PHOTO CAPTION (TOP) P-41490 GLL/EM17 December 22, 1992 This false-color mosaic was constructed from a series of 53 images taken through three spectral filters by Galileo'simaging system as the spacecraft flew over the northern regions of the Moon on December 7, 1992. The part of the Moon visible from Earth is on the left side in this view. The color mosaic shows compositional variations in parts of the Moon's northern hemisphere. Bright pinkish areas are highlands materials, such as those surrounding the oval lava-filled Crisium impact basin toward the bottom of the picture. Blue to orange shades indicate volcanic lava flows. To the left of Crisium, the dark blue Mare Tranquillitatis is richer in titanium than the green and orange maria above it. Thin mineral-rich soils associated with relatively recent impacts are represented by light blue colors; the youngest craters have prominent blue rays extending from them.

TELEPHONE (818) 354-5011 PHOTO CAPTION (TOP) P-41475 GLL/EM15 December 22, 1992 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.
