This behemoth machine is carrying the Artemis 2 Moon rocket out to the launch pad. It carried the Shuttles I launched in too. A massive, clanking crawler and skilled crew, taking infinite care.

Academic vs. media representations of a new Antarctic under-ice dataset. The sequential (University of Grenoble-Alpes) palette emphasizes overall structure, divergent (BBC) emphasizes the extremes.

I've been inside of both a tornado and a volcano! This is a wide angle photo I shot from within the evacuated magma chamber of a volcano, roughly 400 ft below the surface, looking up toward the vent. If you look closely, you'll see the lift in the vent that brought me down! #Photography
