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...
Although better remembered for mapping the Moon, Johann Heinrich M"adler and Wilhelm Beer were the first "areographers". They began by establishing that most of Mars’ surface features were permanent, and more precisely determining the planet's rotation period. In 1840, M"adler combined ten yea...

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 ...
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...
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...
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...
In the case of the Earth and Moon, where the orbital period of the Moon is much longer than the rotation period of the Earth, the same effect that causes one side of the Moon to always face the Earth is causing the Earth's rotation to slow by 1 or 2 thousandths of a second per ...
Theoretically, this error amounts to only one sol in 10,000 Martian years; however, the actual error will depend on the changes in Mars' orbital elements, rotational period, and the rate of the precession of the pole vector over this period of time....
Led by the Mohammed bin Rashid Space Centre (MBRSC) in the UAE, the mission was jointly conceived and developed over a six year period by MBRSC and its Knowledge Transfer partners at the University of Colorado Boulder, Arizona State University, and the University of California, Berkeley. Hope ...
