Spirit soldiers on
The hazard avoidance camera on the front of Nasa’s Mars Exploration Rover Spirit took this image after a drive on the 1 806th Martian day, or sol, (31 January 2009) of Spirit’s mission on the surface of Mars.
The wheel at the bottom right of the image is Spirit’s right-front wheel. Because that wheel no longer turns, Spirit drives backwards dragging that wheel. The drive on Sol 1 806 covered about 30 cm. The rover team had planned a longer drive, but Spirit stopped short, apparently from the right front wheel encountering the partially buried rock visible next to that wheel.
The hazard avoidance cameras on the front and back of the rover provide wide-angle views. The hill on the horizon in the right half of this image is Husband Hill. Spirit reached the hill’s summit in 2005.
