Although possibly the first to make the mistake of describing the Martian year as lasting 687 Martian days, he was far from the last. [40] In the Robert A. Heinlein novel Red Planet (1949), humans living on Mars use a 24-month calendar, alternating between familiar Earth months and newly created months such as Ceres and Zeus. For example, Ceres ...
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 .
The basic intercalation formula therefore allocates six 669-sol years and four 668-sol years to each Martian decade. The former are still called leap years, even though they are more common than non-leap years, and are years that are either odd (not evenly divisible by 2) or are evenly divisible by 10: this produces 6,686 sols per ten years ...
[clarification needed] Mars Orbiter Camera data beginning in March 1999 and covering 2.5 Martian years [14] show that Martian weather tends to be more repeatable and hence more predictable than that of Earth. If an event occurs at a particular time of year in one year, the available data (sparse as it is) indicates that it is fairly likely to ...
Like something where you can put in Earth notation {{Earth to Mars Time|years|months|days}} and get it to spit out "2 Martian years and 78 sols" on the page. Yes, I know it's like going to the auto industry and saying "Hey, let's make a car that gets 200 miles to the gallon" - it's easy to say, and sounds simple; but it isn't - but I'm just ...
Solar longitude, commonly abbreviated as Ls, is the ecliptic longitude of the Sun, i.e. the position of the Sun on the celestial sphere along the ecliptic.It is also an effective measure of the position of the Earth (or any other Sun-orbiting body) in its orbit around the Sun, [1] usually taken as zero at the moment of the vernal equinox.

Mars Year 1 is the first year of Martian timekeeping standard developed by Clancy et al. [1] originally for the purposes of working with the cyclical temporal variations of meteorological phenomena of Mars, but later used for general timekeeping on Mars. Mars Years have no officially adopted month systems.
The chosen orbit was also Sun-synchronous, allowing the daylit side of Mars to always be captured during the mid-afternoon of each Martian Sol. While some instruments could provide a real-time data link when Earth was in view of the spacecraft, data would also be recorded to the digital tape recorders and played back to Earth each day.
