Our sec­ond pan­el today…deals with the inter­sec­tions between Mars as a plan­et, a real phys­i­cal space, and the way that we think about envi­ron­ments in Earth his­to­ry. And nowa­days we know more than we ever have before about the Martian envi­ron­ment and some of the his­to­ry there. But as I men­tioned this morn­ing, in many ways, we’ve still just scratched the sur­face. And so, we want to look in this pan­el at what we can do to think about the explo­ration of oth­er worlds, or human beings liv­ing off-world, in light of the his­to­ry that we’ve had here on our own planet.
