Reading thru lots of little PDF's I've found, i get a figure that mentions up to 12 Gbits for a single full HiRISE image.....BUT - look at this...

To me, it would seem that they might get as few as one full HiRISE image per day ohmy.gif

BUT - at the best data rates of say, up to 6Mbits/sec - 12 Gbits is only 34 minutes of downlink.

Can anyone sync those two facoids? It seems that the suggested performance, and the expected return, don't match by an order of magnitude.
