In case you missed it there's 9 minutes on MSL (actual hardware visible) + 5 minutes with Dr Elachi on "This week in Space" there: http://www.spaceflightnow.com/
14 minutes out of 23 regarding Unmanned, not bad. -------------------- |

Glad to see her coming together so well!
Late comment on duty cycles for complex systems: Ask any aircraft mechanic anywhere in the world how planes behave if they sit idle for too long; you'll get an earful. My guess is that near-continuous operation of a system within normal parameters (vs. near upper tolerances, as is often necessary with high-current devices) actually reduces the likelihood of malfunction since the individual components are subjected to their designed operational loads & environment (thermal being probably the most significant) as well as generally steady inputs from interfacing devices. What frequently kills integrated systems are abrupt transients (mechanical & electrical), and those are more likely to arise due to subtle, often random, changes in the performance of individual components that occur for a variety of reasons as a result of prolonged periods of inactivity. -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.
