I guess Opportunity would be better placed to come out of a low power fault state. Spirit had to try and survive the depths of winter. With the dust storm maximum temperatures will be cool but minimum temperatures will be higher than normal for this time of year and the radioisotope heaters may be able to cope.

I guess Opportunity would be better placed to come out of a low power fault state. Spirit had to try and survive the depths of winter. I'm not sure that the specific failure mode that got Spirit has ever really been identified. The presumption was that it was related to cold, but it would surprise me a little if there was anything about MER that could be rendered non-functional by a few deep thermal cycles. (Well, maybe the batteries, but the system would still work in the daytime.) Hopefully there isn't some inherent flaw in the low power fault state, or better yet, that it never gets entered. -------------------- Disclaimer: This post is based on public information only.
