Our rover might not last that long.

The images provide measurements of surface features and are allowing us to assess the slopes more carefully and develop a map of where the good slopes will be to have our solar panels in a good position.

It looks like a loose rock that is blacker and rougher than the material of Home Plate and so we wanted to spend some time checking that out.

When you look at this image you can really say that Spirit has found some interesting stuff.

Putting all the clues together -- the mineral, chemical and textural clues -- we have found good evidence that there was ground water.

We're interested in finding out whether that bright rim material is the same as the outcrop rock or something different. It may have a different water story.
