The Mercury Messenger spacecraft is being lauched on August 2nd 2004. Mercury is one of the least photographed planets. This mission should be interesting. Although Messenger will only orbit Mercury in 2011. It flies by the planet a couple of times in 2008. Something else to look forward to!<br /><br />http://www.nasa.gov/mission_pages/messenger/main/index.html <br />
