During the Viking Lander missions to Mars in the 1970s, NASA began using the time increment "sol" as the equivalent of a Martian "day" because a day on Mars lasts 24 hours, 39 minutes and 35.244 seconds — about 3% longer than a day on Earth. Timekeeping for a NASA mission to Mars typically begins at Sol 0 when a spacecraft touches down on Martian soil. Curiosity Rover has been rolling around the surface of the Red Planet since 10:32 p.m. PDT on Aug. 5, 2012, more than 2,780 sols ago.
