sol

A local day on a planet, defined by its period of rotation. On Mars, for example, a local day lasts 24 hours and 37 minutes. During the Mars Pathfinder mission, scientists began counting Sols with the successful landing of the spacecraft on July 4, 1997 (Sol 1). Images from the Mars Pathfinder mission always contain a reference to the Sol on which it was taken.
