NASA's Mars Exploration Rover Spirit used its navigation camera to take the images combined into this 210-degree view of the rover's surroundings during the 1,861st to 1,863rd Martian days, or sols, of Spirit's surface mission (March 28 to 30, 2009).
The center of the scene is toward the south-southwest. East is on the left. West-northwest is on the right.
The rover had driven 22.7 meters (74 feet) southwestward on Sol 1861 before beginning to take the frames in this view. The drive brought Spirit past the northwestern corner of Home Plate.
In this view, the western edge of Home Plate is on the portion of the horizon farthest to the left. A mound in middle distance near the center of the view is called "Tsiolkovsky" and is about 40 meters (about 130 feet) from the rover's position.
This view is presented as a cylindrical projection with geometric seam correction.
