To be fair, most modern (CMOS) digital cameras work like that too, it's called a rolling shutter. The scanning speed is the cause of that wobbly effect you see on videos made with mobile phones.

True, but if you can do 1m fps on earth[1] and the MRO travels at a speed of 133,879.68 inches/second then you could take 7.4693934 pictures per inch even if you had a rolling "scanning" shutter. I know that would be way to much data for them to process, but for the 172 seconds from parachute deployment to touchdown you could have one amazing high speed film.
I am sure NASA can fund a high speed camera for MRO... or do we need to crowdfund that one as well... [1] http://www.youtube.com/watch?v=QfDoQwIAaXg
