There is a list of interesting topics, including the MER audio briefings, at these two sites: http://www.jpl.nasa.gov/multimedia/ and<br />http://www.jpl.nasa.gov/multimedia/index.cfm?MMCategory=Audio <br />Unfortunately, the accompanying images may no longer be available -- at least I was unable to find them like I did the first time I looked, on about 11/10/04. But the audio is plenty interesting on its own. <div class="Discussion_UserSignature"> </div>
