The following account was recorded in the agent's log during your transmission: Umm, rocks are piled up in massive, haphazard stacks throughout a massive asteroid crater, some of them reflecting an otherworldly blue-purple sheen in the low-angle sunlight filtering in from the rim. Air's still and dry, with an acrid metallic scent, like from an arc welder or something. The crater's somehow containing an internal, self-sustaining rain cycle – water vapor's condensing into droplets and then raining back down on the rocks, feeding these wispy, alien-looking vines that're crawling all over the boulders, even as the entire scene remains bone-dry outside this localized weather anomaly.
