Hi-res images from HiRISE: a transform fault on Mars
HiRISE (The High Resolution Imaging Science Experiment) is on the Mars Reconnaissance Orbiter (MRO) and offers 1 meter / pixel resolution. They've just taken a few images from yesterday and released them. (The official blurb says the resolution is 25cm/pixel on this image).
Big images--this one is a 1.3MB JPEG, it shows a region in Valles Marineris called Ius Chasma.
Take a look in the middle of the big image, or look at my crop above--that sure looks like a transform fault!

UPDATE: They've spotted it and added commentary. They are intrepreting it as a thrust fault tilted on its side. Great resolution on their images.
