Our sun observing spacecraft took a spin! On July 6, engineers instructed the Solar Dynamics Observatory to roll 360 degrees on one axis. It 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.
