This site currently resides at the Goddard Space Flight Center and was redesigned in February of 2001.

The following tools were used to create the site:

• HTML 4.0 (see, for example, The HTML 4.0 Sourcebook).
• The extremely powerful Gnu Image Manipulation Program (GIMP).
• GNU Emacs .
• Images from Polar and NASA.

The Curator for this site wholeheartedly welcomes comments, problems, and suggestions. Please email me.
