• To figure out what kind of rock Barnacle Bill is, the camera on the Pathfinder craft was to take high-resolution pictures Tuesday using 12 different filters designed to let geologists identify mineral types by their characteristic colors.
• By the time that final results of the mission were described in a series of articles in the Journal Science ( December 5, 1997 ), it was believed that the rock Yogi contained a coating of dust, but was similar to the rock Barnacle Bill.
