What to Expect When Curiosity Starts Snapping Pictures
nasa.govThey should put a terabyte of solid storage on the orbiter(s) and just have it send stuff from the surface non-stop and then stream back to earth so there's zero downtime in the signals...
But I guess once you've seen a mars rock in highdef, for the untrained they are all mostly the same... interest will be sadly waining after a month.
So...only the Hazard Cameras are active, the rest are closed until Curiosity is finished with self-tests?
There is a picture from the MAHLI:

the best camera is the one you have with you
