There is no end to the fascinating geology, the inner and outer workings of the planets, their moons, asteroids, comets and other space flotsam and jetsam. It has almost become commonplace, that new data and images announce some new discovery, often unexpected, even weird. Satellites and landing craft sample atmospheres and rocks, give witness to distant eruptions and collisions, or search for possible landing sites for futures explorations.
I’ve never been involved in this kind of geological exploration, but I do enjoy writing about it, and in my imagination conduct geological field work in an ancient Martian river channel.
The posts linked here are in no particular order. For pictorial images I rely mostly on those available from NASA and the European Space Agency (ESA) that are publicly available.
