This map shows the Mars Exploration Rover Spirit's travels since arriving on the red planet Jan. 3, 2004 PST. Spirit is on its way to a large crater nicknamed "Bonneville." On the 45th day, or sol, of its mission (Feb.18, 2004), it stopped off at the shallow depression dubbed "Laguna Hollow" to investigate the fine-grained soil contained there. The rover is not far from Bonneville's ejecta, the blanket of material expelled from the crater when it was hit by whatever celestial object created it. So far, Spirit has traveled about 120 meters from its lander. Data within the yellow box represent a digital map made of images taken by rover's panoramic and navigation cameras. Data outside this box are a composite of images from the rover's descent image motion estimation system camera and the orbiter Mars Global Surveyor.
