The map came from Mars Global Surveyor, and was created early in
that mission. You can see it at:

http://www.msss.com/mars_images/moc/7_19_99_fifthMars/01_daymap/

The caption says that "...The high southern latitudes at the bottom
of the image (from about 60°S to 90°S) are black because this region
was in total winter darkness at the time the data were collected."
About the best I can suggest at present is to use one of the other
Mars maps. (Click on Mars, then on Display... Options; you will
see a list of available maps.)

I've hopes of adding more maps, for Mars and some other objects.
