If this got you worried about the calendrical complications facing future Mars settlers, you might find some consolation in the fact thatno one will ever settle on Jupiter. Jupiter has different rotation periods per latitude, so devising a calendar system for the gas giant would pose a whole n...
2016. The ultraviolet colors of the planet have been rendered in false color, to show what we would see with ultraviolet-sensitive eyes. The movie uses four MAVEN images to show about 7 hours of Mars rotation during this period, and interleaves ...
Phobos rises in the west, sets in the east, and rises again in just 11 hours. Deimos, being only just outside synchronous orbit—where the orbital period would match the planet's period of rotation—rises as expected in the east but very slowly. Despite the 30 hour orbit of Deimos, it...

Because of the rotation period of Mars, the view of the planet changes slightly from night to night. Mars rotates in the same direction as Earth every 24 hours and 37 minutes, just a little longer than the rotation period of Earth. If you observe Mars with a correct view with north up...

Whereas a year on Mars is significantly longer than a year on Earth, the difference between an day on Earth and a Martian day (aka. “Sol”) is not significant. For starters, Mars takes 24 hours 37 minutes and 22 seconds to complete a single rotation on its axis (aka. a sidereal day...
is what we Earthlings usually mean by the word “day.” It’s the 12 a.m. on Monday to 12 a.m. on Tuesday kind of day. A sidereal day (pronounced si-der-e-al) is more like a planet’s true rotation period, relative to the rest of the universe. Why are these things different...
The Moon varies in orbit around Earth, going from 362,600 km at perigee to 405,400 km at apogee. And like most known satellites within our Solar System, the Moon’s sidereal rotation period (27.32 days) is the same as its orbital period. This means that the Moon is tidally locked with...
struck Mars. The impact of those objects created craters of all sizes. The Noachian was also a time of great volcanic activity. In addition, erosion by water probably carved the many small valley networks that mark Mars's surface during the Noachian Period. Liquid water requires higher atmospher...
