Interestingly, that's apparently not quite correct. From the ESA link in the article:
> Rosetta's original trajectory and engineering design did not include an eclipse, but unavoidable launch delays forced the trajectory to be replanned. Mission controllers working on Rosetta have spent months carefully planning and testing a low-power configuration which will allow the spacecraft to safely operate on batteries.
No way everyone can click through every link in every article they read. Glad we were jointly able to bring something interesting from the article to people's attention.
