The Clancy Mars year is reckoned from one Martian northward equinox to the next (L s = 0°), and specific dates within a given year are expressed in L s. The Clancy Mars year count is approximately equal to the Darian year count minus 183. The Allison Mars sol date epoch equates to L s = 276.6° in a year that is undefined in the Clancy Mars ...
Mars Pathfinder used the local apparent solar time at its location of landing. Its time zone was AAT-02:13:01, where "AAT" is Airy Apparent Time, meaning apparent (true) solar time at Airy-0. The difference between the true and mean solar time (AMT and AAT) is the Martian equation of time.
Sol (borrowed from the Latin word for sun) is a solar day on Mars; that is, a Mars-day. 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.
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 ...
The days were named after the classical planets of Hellenistic astrology, in the order: Sun , Moon , Mars , Mercury , Jupiter , Venus , and Saturn . [6] The seven-day week spread throughout the Roman Empire in late antiquity. By the fourth century CE, it was in wide use throughout the Empire.
Water was first discovered on Mars in 2008 by NASA’s Phoenix Mars lander. The agency’s rovers have been exploring the Martian surface and looking for the ingredients and signs of ancient ...
The idea of transforming Mars into a world more hospitable to human habitation is a regular feature of science fiction. Scientists are now proposing a new approach to warm up Earth's planetary ...
Mars is the fourth planet from the Sun.The surface of Mars is orange-red because it is covered in iron(III) oxide dust, giving it the nickname "the Red Planet". [22] [23] Mars is among the brightest objects in Earth's sky, and its high-contrast albedo features have made it a common subject for telescope viewing.
