Panels? I thought those were for writers, specifically professionals. In any case, I doubt that the folks dressed up as comic, Star Trek, etc. characters would be interested in rover planning and scheduling software, Mars drilling, field-deployed wireless exploration communications, impact crater geophysics, or the current mission design reference trades for Project Constellation (the new human exploration initiative to the Moon and eventually Mars). Maybe some historical stuff on SETI would garner interest, given the reaction to the shirt there... hmm.

In any case, hope that the algae disappears... the fish would be easier to see, too :).
