Astronaut Don Pettit posting from space…

Post List[Letters to Earth: Astronaut Don Pettit].

Looking through the cupola windows on Space Station, it’s only natural to reflect upon who we are and where we fit into the world below. Like something out of Alice in Wonderland, this orbital looking glass can be both a window through which to observe the jeweled sphere of Earth and a mirror that (sometimes, depending on your viewing angle) shows you a translucent reflection of yourself superimposed on the planet.

From orbit, the more you know about our planet, the more you can see. You see all the geological features described in textbooks. You see fault zones, moraines, basins, ranges, impact craters, dikes, sills, braided channels, the strike and dip of layered rocks, folding, meanders, oxbow lakes, slumps, slides, mud flows, deltas, alluvial fans, glaciers, karst topography, cirques, tectonic plates, rifts zones, cinder cones, crater lakes, fossil sea shores, lava flows, volcanic plumes, fissures, eruptions, dry lakes, inverted topography, latteric soils, and many more.
