The Mars time of noon is 12:00 which is in Earth time 12 hours and 20 minutes after midnight. For the Mars Pathfinder, Mars Exploration Rover (MER), Phoenix, and Mars Science Laboratory missions, the operations teams have worked on "Mars time", with a work schedule synchronized to the local time at the landing site on Mars, rather than the ...
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).
A sol is the apparent interval between two successive returns of the Sun to the same meridian (sundial time) as seen by an observer on Mars. It is one of several units for timekeeping on Mars. A sol is slightly longer than an Earth day. It is approximately 24 hours, 39 minutes, 35 seconds long.
Mars is rotating more quickly than it used to, according to data that NASA’s InSight lander collected on the red planet. ... A Martian day lasts about 40 minutes longer than a day on Earth ...
up to one Sun or Moon diameter (about 0.5° or 30') every 2 minutes; up to one diameter of the planet Venus in inferior conjunction (about 1' or 60") about every 4 seconds; 2,000 diameters of the largest stars per second; Star trail and time-lapse photography capture diurnal motion blur. The apparent motion of stars near the celestial pole ...
Spotting Mars at opposition is easier than you might think because the planet will stand out due to its color and radiance. Instead of appearing a whitish yellow shade like the stars, it will be a ...
[1] [2] The planet orbits the Sun in 687 days [3] and travels 9.55 AU in doing so, [4] making the average orbital speed 24 km/s. The eccentricity is greater than that of every other planet except Mercury, and this causes a large difference between the aphelion and perihelion distances—they are respectively 1.666 and 1.381 AU.

Rotation and Interior Structure Experiment (RISE) is a radio science experiment onboard InSight Mars lander that will use the spacecraft communication system to provide precise measurements of Mars' rotation and wobble. RISE precisely tracks the location of the lander to measure how much Mars's axis wobbles as it orbits the Sun.
