Who ordered the Martian pizza? As Mars Pathfinder [ http://mpfwww.jpl.nasa.gov/default1.html ] and its mobile robot Sojourner [ http://mpfwww.jpl.nasa.gov/rover/sojourner.html ] continue to explore [ http://mars.sgi.com/default.html ] Mars [ http://www.seds.org/nineplanets/nineplanets/mars.html ], new and interesting rocks are being discovered, even though the primary mission [ http://www.jpl.nasa.gov/releases/pfprime.html ] has been successfully completed. The rock [ http://eis.jpl.nasa.gov/~skientz/little_rock/ ] pictured above [ http://mpfwww.jpl.nasa.gov/ops/sol71.html ] has been dubbed "Half Dome" and was visited by Sojourner in late August. The shape and fine-scale textures of Half Dome are still being studied. As part of the extended mission, Sojourner [ http://antwrp.gsfc.nasa.gov/apod/ap970814.html ] has been sent on its longest journey yet [ http://www.jpl.nasa.gov/releases/pfextend.html ] - a 50 meter stroll around the Sagan Memorial Station [ http://antwrp.gsfc.nasa.gov/apod/ap970710.html ].
