Here's a full-resolution picture taken by the descent imager as the heat shield fell away:

The descent imager uses the same sensor as the main mast cameras, but with different optics.

If that camera works for 10+ years, I'll take that resolution any day! Beautiful!

If you want to blow up a giant printout wait for the stitched-together shots, I suppose.

I haven't found any full resolution examples, but there's a resized sample here: http://mars.jpl.nasa.gov/msl/mission/instruments/cameras/mas...
