Signs of a Busy Rover

January 10, 2005
This image taken by the navigation camera on the Mars Exploration Rover Opportunity shows the first seven holes the rover drilled into the slopes of "Endurance Crater." Starting from the uppermost pictured (closest to the crater rim) to the lowest, the holes were drilled on sols 138 (June 13, 2004), 143 (June 18), 145 (June 20), 148 (June 23), 151 (June 26), 153 (June 28) and 161 (July 7), respectively. Each hole is 4.5 centimeters (1.8 inches) in diameter.

Each of the holes has a name for the rock it is on, and for the specific target on the rock. On the rock "Tennessee," the target is "Vols;" on the rock Kentucky, the target is "Cobblehill;" on the rock "Virginia," the target is Virginia; on the rock "Ontario," the target is "London;" on the rock "Manitoba," the targets are "Grindstone" and "Kettlestone;" on the rock "Millstone," the target is "Drammensfjorden."
