The International Space Station orbits Earth at roughly 250 miles up, moving at about 17,500 miles per hour, and this film uses that vantage point to build a time-lapse record of the planet turning below it. Astronaut Ron Garan, who flew on Expeditions 27 and 28, narrates the footage and makes the case for why NASA bothers with it: he argues that seeing the planet this way turns viewers from spectators into something closer to crew, invested in what the space program is actually doing up there. The film walks through how the images get made, from cameras mounted to withstand vacuum and radiation to the editing that turns thousands of still frames into smooth motion of auroras, city lights, and cloud systems sliding across continents. There's little narrative beyond that process and Garan's framing of it, but the footage itself, city grids at night, lightning storms seen from above, is the point, and it runs uninterrupted long enough to let the orbital motion register.
