Most of our time on this simulated Mars mission is spent inside a geodesic dome. We conduct research, make and document meals for our food study, do chores, and fill out psychological and behavioral surveys. It’s no surprise, then, that adventure is hard to come by. But on Wednesday of this week, three of us gave it our best shot.
We donned our green spacesuit simulators and took a hike. For two and a half hours, we clambered over the shifty and crumbling lava rocks just east of our habitat. We walked to the edges of pits and peered over steep drop-offs. And we investigated a nearby lava tube cave, hollowed out years ago by an immense column of molten lava.
