SUMMARY: The most intriguing part about Opportunity's landing spot is the big slab of bedrock exposed on the rim of the crater the rover is in. The region is important because it means that planetary geologists know where this rock was formed - right there. Other rocks can be moved by water and wind erosion, volcanic events or asteroid impacts, but this bedrock hasn't been moved. When the rover is ready to drive off its lander, it will climb up to the bedrock and examine it carefully for any layers that could answer if there was once standing water in this region. And where there was once water, there could be life.
