The average duration of the day-night cycle on Mars — i.e., a Martian day — is 24 hours, 39 minutes and 35.244 seconds, [3] equivalent to 1.02749125 Earth days. [4] The sidereal rotational period of Mars—its rotation compared to the fixed stars—is 24 hours, 37 minutes and 22.66 seconds. [4]
The basic time periods from which the calendar is constructed are the Martian solar day (sometimes called a sol) and the Martian vernal equinox year.The sol is 39 minutes 35.244 seconds longer than the Terrestrial solar day, and the Martian vernal equinox year is 668.5907 sols in length (which corresponds to 686.9711 days on Earth).
Thus, the MSD is a running count of sols since 29 December 1873 (coincidentally the birth date of astronomer Carl Otto Lampland). Numerically, the Mars Sol Date is defined as MSD = (JD − 2451549.5)/1.0274912517 + 44796.0 − 0.0009626, where JD is the Julian Date using Terrestrial Time. [6] [7]

The calculation takes into account that a Mars Sol is a few dozen minutes longer than an Earth day. NASA and secondary sources provide Sol numbers, but do not always give a UTC time or any Earth time zone for the events on Mars. NASA provides photographs from the events with a timestamp in local Mars time that facilitates the calculation. See here.
Along with hitting a record-setting altitude of 40 feet, the helicopter clocked its first mile on its 152nd sol (Mars day) after landing with Perseverance in February. Tweet may ha.
