  Title: Moon taken by Galileo after completing its first Earth Gravity Assist
  Description:
  Galileo spacecraft images of the Moon were taken at (right photo) 6:47 pm 
  Pacific Standard Time (PST), 12-08-90, and at (left photo) 9:35 am PST, 
  12-09-90, at a range of more than 350,000 miles.  The picture on the right 
  shows the dark Oceanus Procellarum in the upper center, with Mare Imbrium 
  above it and the smaller circular Mare Humorum below.  The Orientale Basin, 
  with a small mare in its center, is on the lower left near the limb or
  edge.   Between stretches the cratered highland terrain, with scattered
  bright young  craters on highlands and maria alike.  The picture at left
  shows the globe of  the Moon rotated, putting Mare Imbrium on the eastern
  limb and moving the  Orientale Basin almost to the center.  The extent of
  the cratered highlands  on the far side is very apparent.  At lower left,
  near the limb, is the  South-Pole-Aitken basin, similar to Orientale but
  very much older and some  1,200 miles in diameter.  This feature was
  previously known as a large  depression in the southern far side; this
  image shows its Orientale-like  structure and darkness relative to
  surrounding highlands.  Photo was provided  by Jet Propulsion Laboratory
  (JPL) with alternate number P-37364, 12-19-90.
