This color picture of Antarctica is one part of a mosaic of pictures covering the
     entire Antarctic continent taken during the hours following Galileo's historic first
     encounter with its home planet. The view shows the Ross Ice Shelf. An occasional
     mountain can be seen poking through the ice. It is late spring in Antarctica, so the
     sun never sets on the frigid, icy continent. This picture was taken on December 8,
     1990.
