                    Ulysses, launched in 1990, circles the sun in a unique orbit 
                    that carries it over both the sun's poles and equator, giving 
                    Ulysses a global view of solar wind activity:</FONT></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://science.nasa.gov/headlines/y2008/23sep_solarwind.htm"><div align="center"><img src="http://content6.clipmarks.com/blog_cache/science.nasa.gov/img/5D165016-123C-470A-A0A8-318437481B08" alt="" /></div></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://science.nasa.gov/headlines/y2008/23sep_solarwind.htm"><FONT face="Verdana, Arial, Helvetica, sans-serif" size="2"><STRONG>Above:</STRONG>
