Has anyone any idea what kind of imaging system is being proposed for the MSL? Would it be the same or simiilar to the MER's, or as improved as the MER pancams are to those that were used on Pathfinder?
With a nuclear power source for the rover, and hopefully the mars telecoms orbiter in place the data rate and data volume could be phenomenal |

The MER Navcam lenses (esp. Oppy's) have dust accumulations ranging from light to very heavy -- Oppy's are quite occluded on the right sides of the images. However, this isn't a result of general dust accumulation, it happened almost entirely during the global dust storm (which also deposited dust onto the "protected" optics of the mini-TES instruments on both MERs, enough that it might possibly render the devices useless).
I think there's a difference between designing optics to remain "as clean as possible" during normal accumulation cycles and designing dust-storm-proof optics. I'm positive that MSL's cameras are good for the former, but doubt they're designed to handle the latter. -the other Doug -------------------- “The trouble ain't that there is too many fools, but that the lightning ain't distributed right.” -Mark Twain

Aren't they concerned enough to make a mechanism for removing dust from the lenses? If I recall well, the Beagle 2 lander had a 'wiper' for each eye of its stereo imaging payload. Why on earth won't anyone consider such a thing? -------------------- |
