I'll be curious what kind of resolution the newly arrived MRO will provide..
hopefully Opportunity will be able to get some good shots of the outcrops
The High Resolution Imaging Science Experiment camera consists of a 0.5 meter reflecting telescope, the largest of any deep space mission, and has a resolution of 1 microradian, or 0.3 meter at a height of 300 km. (For comparison purposes, satellite images of Earth are generally available to a resolution of 0.1 meter, and satellite images on Google Maps are available to 1 meter.[8]) It can image in three color bands, 400-600 nm (blue-green or B-G), 550-850 nm (red) and 800-1,000 nm (near infrared or NIR).Not too shabby! :-)
