Explanation: Broken metal and scorched Mars make the impact site of Opportunity's heat shield one of the more interesting sites inspected by the rolling robot.
Visible on the image left is the conical outer hull of the shattered heat shield expelled by Opportunity as it plummeted toward Mars last year.
Scrolling right will show not only another section of the heat shield but the impact site itself.
The site is of interest partly because its creation was relatively well understood.
The impact splattered subsurface light red dirt, while a darker material appears to track toward the large debris.
