On July 6, 2016, engineers instructed NASA’s Solar Dynamics Observatory, or SDO, to roll 360 degrees on one axis. SDO dutifully performed the seven-hour maneuver, while producing some dizzying data: For this period of time, SDO images – taken every 12 seconds – appeared to show the sun spinning, as if stuck on a pinwheel.
Who’s visiting who? This chart of solar system exploration shows every robotic space probe currently exploring (or about to explore) a major solar system object… except for the Earth and Sun of course, because there are way to many of those to show on one chart.
We are used to see the epic, awe-inspiring, perfect photos from the golden age of NASA, during the Mercury, Gemini, and Apollo missions. Those are not the photos that you will find in Drewatts Bloomsbury's auction. These are all pretty shitty—poorly exposed, badly framed, out of focus, or just plain boring.
