     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:

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.
The Galileo project, whose primary mission is the exploration o.f
the Jupiter system in 1995-97, is managed for NASA's Office of
Space Science and Applications by the Jet Propulsion Laboratory.

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.  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.

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.  The Galileo project, whose primary mission is the
exploration of the Jupiter system in 1995-97, is managed for

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.  The Galileo project, whose primary mission is the
exploration of the Jupiter system in 1995-97, is managed for

                                                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.  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.
