Barnacle Bill And Sojourner

Deployed on a pop-up mast [ http://imp.lpl.ariz…] to its full height, the Sagan Memorial Station [ http://mars.compuse…]'s IMP camera now stands about 5 feet above the surface of Ares Vallis - on Mars [ http://antwrp.gsfc.…]. This is one of the first images [ http://www.jpl.nasa…] from its new vantage point, showing the rover Sojourner near a rock named Barnacle Bill. This particularly interesting rock, with a variety of surface textures, appears to be about 8 to 10 inches high. Sojourner performed [ http://antwrp.gsfc.…] an analysis of Barnacle Bill by successfuly maneuvering to place its Alpha Proton X-Ray Spectrometer [ http://mars.compuse…] (APXS) instrument against the rock. The APXS, located at the rear of the rover, is not visible in this picture. Sojourner's next destination is ... a rock named Yogi. Results describing the composition of Barnacle Bill, the martian soil and a color panorama of the landing site will be presented at a Pathfinder press briefing [ http://www.jpl.nasa…] today scheduled for 11:00 AM Pacific Daylight Time.
