It was, however, hoped and even expected that they would last two to four "lifetimes." The "design" lifetime is, in effect, the length of the warranty, the period of maximum assurance of full function. But few would have been willing to predict they would be effectively functional in their thirteenth "lifetime"! http://www.engineeringnews.co.za/article.php?a_id=111921 Sterling K.

I seem to recall asking Ed Stone before launch about how long they hoped them to last, and he told me two weeks. So the current criticism about how NASA has to ask for continuing funding for operations seems entirely unwarranted. The reason for my interest in this is that I was looking at running russian rovers through the private sector back in the early 90's. I analyzed Gump et al's else's business plans, and came up with a variant that I thought would work. This was before the internet, and the plan I came up with was to ship Mars images in realtime to museums via private lines, where shows would be given with projection TV systems. After these two rovers are dead, I think that if one can use the converted Russian ICBM launchers (say about $5-10 million) for launch, and the little 4 wheel rover from Mashinotroeniye (price unknown), and ships the images from Mars via the internet for a nominal subscription fee, the plan might work. Hit numbers and lifetimes are of great interest for such a scheme. How is this meteorite related? Well, the rovers are finding meteorites, and by the way, I still would like to be acknowledged for spotting the first meteorite on Mars, which I mistakenly identified as a tektite. Can anyone dig up a URL for that post? I made the mistake of shipping a 39k image of it to the list then - my apologies. good hunting (great stuff, rueben!), E.P.
