For purposes of enumerating Mars years and facilitating data comparisons, a system increasingly used in the scientific literature, particularly studies of Martian climate, enumerates years relative to the northern spring equinox (L s 0) that occurred on April 11, 1955, labeling that date the start of Mars Year 1 (MY1).
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).
Mars Years have no officially adopted month systems. Scientists generally use two sub-units of the Mars Year: the Solar longitude (L s) system: 360 degrees per Mars Year that represent the position of Mars in its orbit around the Sun, or; the Sol system: 668 sols per Mars Year. This system consists of uniform time units. However, Mars Year sols ...
The large eccentricity causes the insolation on Mars to vary as the planet orbits the Sun. (The Martian year lasts 687 days, roughly 2 Earth years.) As on Earth, Mars' obliquity dominates the seasons but, because of the large eccentricity, winters in the southern hemisphere are long and cold while those in the north are short and relatively warm.
A Martian year is approximately 668.6 sols, equivalent to approximately 687 Earth days [1] or 1.88 Earth years. The sol was adopted in 1976 during the Viking Lander missions and is a measure of time mainly used by NASA when, for example, scheduling the use of a Mars rover .
A collection of Martian rocks could reveal details about potential past life on the Red Planet – but first NASA has to get them back to Earth.. For years, the U.S. space agency's Perseverance ...

Extra-close oppositions of Mars happen every 15 to 17 years, when we pass between Mars and the Sun around the time of its perihelion (closest point to the Sun in orbit). The minimum distance between Earth and Mars has been declining over the years, and in 2003 the minimum distance was 55.76 million km, nearer than any such encounter in almost ...
