Your "rewrite" rules are not taking affect (as evident by the fact that apache 
is looking for a folder named "galaxy" in your document root folder 
(/usr/local/apache/htdocs/).

First thing to try is to take the "RewriteRules" statements outside the 
"<location>" block.

Then, enable mod_rewrite logging with the following two statements:
  RewriteLog /tmp/rewrite.log
  RewriteLogLevel 9

and restart apache.
you'll then see every URL access in "/tmp/rewrite.log", and whether mod_rewrite 
handled it or not.
