Spirit - 2010 Winter@Troy, The first stationary science campaign Options

[Astro0]

Well, with perhaps a few more weeks of tilt-enhancing drives to go and then settling in for the winter, I thought it might be a good time to have a thread dedicated to ideas and observations that will come. It's likely that we won't hear much from Spirit during the coldest part of winter (April-June) possibly longer. There'll hopefully be beeps to tell us that she's still alive.

Already there are plans for radio science and determining the fluidity or otherwise of the Martian core, plus weather observations, surface changes etc.
What else could you think of that Spirit could do? Remember that she's not going anywhere (vonBraun is out)

In the meantime, have you sent your postcard to Spirit yet?! It's a great idea from the Mars outreach team.

What would you say to Spirit?

Something I've been wondering about for some time, (Mods move this if I'm posting in the wrong topic):
When/where did Spirit last catch a glimpse of the lander? I don't recall it being visible from the top of Husband Hill, due to haze and/or distance, so it must have been much earlier than that, correct? Looking at the panorama, It would be nice to see a sort of 'goodbye' image, like when Oppy left Eagle crater and took some last photos of the place.
