| Above, one of many pictures sent back from Mars of a rock garden near the Pathfinder. The red arrow points to "Barnacle Bill," the first rock scientists studied on the robot rover's trip from the Mother Ship. | Scientists on Earth, meanwhile, discovered a rock which, some scientists believe, both comes from Mars and contains microscopic Martian life. Whether the life is really Martian, though, is still being debated. |
