GALILEO EARTH-MOON FLYBY ANIMATIONS                    March 1993


This black-and-white animation of the Earth and Moon as seen by
the Galileo spacecraft is available in the following format:

     -- EARTMO.FLI, an animation in FLI for PC and Unix

The following viewing software is available in the previous
directory:  Play version 0.80 for MS-DOS (PLAY.ZIP); xanim
(XANIM.Z) and xflick (XFLICK.Z) for Unix/X-Windows.
There is a program 'uncompre.exe' for MS-DOS
to uncompress the .Z files too.

The animation is part of a time-lapse sequence taken by the
Galileo spacecraft on December 16, 1992, eight days after its
flyby of the Earth-Moon system en route to Jupiter.  The full-
color sequence used the 0.968, 0.727 and violet filters; this
black-and-white version was made with the 0.968-micron filter so
that both vegetated and unvegetated land masses appear bright in
contrast to the oceans.  The 46 frames span 15 hours of motion by
the Earth, Moon and spacecraft as viewed from the perspective of
Galileo, with south at the top.  Visible are the Pacific basin,
Australia, Southeast Asia, India, and finally Arabia and the horn
of Africa.  A remarkable feature of this sequence is the specular
reflection or sun glint from the sea surface.  Depending on the
roughness of the water the extent of specular reflection varies
rapidly, expanding over rough seas and contracting to a point
over still oceanic pools such as near the west coast of
Australia.
