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 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).

In summer 1965, the first close-up images from Mars showed a cratered desert with no signs of water. [1] [2] [3] However, over the decades, as more parts of the planet were imaged with better cameras on more sophisticated satellites, Mars showed evidence of past river valleys, lakes and present ice in glaciers and in the ground.

Earth orbits the sun in a slightly uneven circle, keeping an average distance of 93 million miles. Mars’s orbit is much more elliptical—with an aphelion, or furthest remove from the sun, of ...
During the ordinary course of day to day life, we tend to think of planets as being unmoving and unchanging. There are few things more dependable than the ground beneath our feet, but that’s ...
Echus Chasma is a chasma in the Lunae Planum high plateau north of the Valles Marineris canyon system of Mars. It is in the Coprates quadrangle. [1] Clay has been found within it, meaning that water once sat there for a time. [2] It may have been one of the many lakes that have been advanced for the Martian past.
