Go Home, SDO. You’re Drunk.

Every year, NASA's Solar Dynamics Observatory performs a “roll maneuver”, spinning around as it points to the Sun. This is done for many reasons, including to help define exactly where the Sun's spin axis is, which makes it easier for the various cameras on the satellite to compensate for the Sun’s motion as they take data.

Sound technical? It is. But that doesn’t mean we can’t have fun with it.

Oh, how I wish the satellite were named Rick.
