Um, how about survival? I think we all agree that it's a good idea
to put some distance between the earth and oneself once people
start toying with nanoweapons and such. If I remember correctly,
even Eliezer himself proposed a nanolab in space/on the moon to
make sure that the technology (and the species) doesn't get lost
in a future conflict/accident. If you consider that to be feasible,
then there's no reason to reject the Mars variant of this idea.

Who needs a full-blown civilization? All you need is a colony which can
sustain itself until uploading, or at least advanced human-machine
integration becomes possible (likely a couple of decades).

The real innovations usually come from a handful of people, the
rest does work which can (certainly by the time that this would
take place, say 20 or 30 years in the future) be automated to
a high degree. Especially if you include weak AI, but even without
that. Food etc. would be partially brought along (as with today's
space missions), and the rest would be grown on location in
automated greenhouses (meat could be grown in vitro). Only
a handful of specialized people would be needed for maintainance
(this assumes that the scientists wouldn't have any knowledge
whatsoever of such matters, which is unlikely).
Note that equipment can be sent to Mars well in advance of
the actual mission, so you can have quite a pile when you
arrive, and you don't have to drag everything along during the
mission. Also, if (in retrospect) it turns out that the earth won't
be destroyed after all, the Mars colony can stay in touch and
abreast of the latest tech "back home", which can be implemented
on the base.
