Perhaps a new topic is in order at the very special occasion of 3000 sols for Oppy. Congratulations to everyone on the team for what's become a truly epic mission. And with a whole new destination ahead of her: Tribulation! smile.gif wheel.gif

The MER filenames clock has now turned to sol 3000, a bit before the jpl site and SPICE:

Congratulations to the whole MER team -- designers, fabricators, testers, operators, planners, managers, etc.! Remarkable to have a rover operating so long with so much capability still remaining. It would be ironic if a photovoltaic-powered craft was able to operate longer on the surface of Mars than a radioisotope-powered one. :-)

There are more reasons that just longevity when it comes to having an MMRTG on Curiosity. Reliability for one ( 2400Whrs/sol rather than 900, then 700, then 300, then camp for winter at 200 etc etc etc ) An MMRTG also produces a lot of spare heat to keep the rover itself warm.

I wrote that it would be ironic for a MER to operate longer than MSL, because solar cells 1) are subject to dust accumulation and slant-angle/darkness issues to which an RTG is not susceptible, and 2) do not produce the critical heat of an RTG. If Curiosity manages to operate longer than Opportunity then no irony will have occurred. :-) Let's hope that turns out to be the case!
