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 ...
Twilight lasts a long time after the Sun has set and before it rises, because of all the dust in Mars' atmosphere. At times, the Martian sky takes on a violet color, due to scattering of light by very small water ice particles in clouds.

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.
When this happens, Earth sits directly between Mars and the Sun, positioning the red planet directly opposite of the Sun in the sky. Because of this, Mars will look grander and more vivid than ...
The best time to see the planetary parade in January is during the first couple of hours after the Sun goes down, with Saturn and Venus appearing close to each other in the southwest, Jupiter high ...
Sky-gazers can look forward to catching glimpses of four bright planets at the same time in the night sky. Venus and Saturn will appear in the southwest, Jupiter will gleam overhead, and Mars will ...
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 ...
