Spirit's View From 'Troy'
Today, Aug. 18, 2009, marks the Mars Exploration Rover Spirit's 2,000th sol, or Martian day, on the Red Planet.
This scene combines seven frames taken by the navigation camera on Spirit during the 1,891st Martian day, or sol, of Spirit's mission on Mars (April 28, 2009). It covers a vista from south-southeast on the left to northeast on the right.
The site from which Spirit obtained this view has been informally named 'Troy.' Layers of differently hued soil uncovered by the sinking wheels became the subject of intense analysis by the instruments on Spirit's robotic arm.
