Rod HiltonI have a feeling I'm about to get a lot of activity today
Carolyn Porco@rodhilton I do know about space exploration and he says outrageously stupid shit about that, too. Don't get distracted by rockets. Listen (or rather, don't listen) to what he says about living on Mars.

@carolynporco @rodhilton I find it amusing when he explains that the sun will eventually expand to engulf the Earth and so we had better be a multi-planetary species. Yes, we better get our act together before that happens in about four billion years.
