Mars sol. 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.
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).
This suggested that a calendar based on the sol and the Martian year might be a useful timekeeping system for astronomers in the short term and for explorers in the future. For most day-to-day activities on Earth, people do not use Julian days, as astronomers do, but the Gregorian calendar, which despite its various complications is quite ...

Seasons. Mars has an axial tilt of 25.19°, quite close to the value of 23.44° for Earth, and thus Mars has seasons of spring, summer, autumn, winter as Earth does. As on Earth, the southern and northern hemispheres have summer and winter at opposing times. However, the orbit of Mars has significantly greater eccentricity than that of Earth.
Images were taken around 12:00:00 +/- 00:05:00 Martian local mean solar time each Martian day through out the rover's mission (10+ years). The images span from sol 2 to sol 3203. In each image the shadow cast by the gnomon is marked with a color corresponding to the solar longitude, which is a measure of the Martian year in degrees (e.g. solar ...
Others on this list reflect on the legacy your late father left behind. This quote by Connie Britton is a good example: “He shaped me into who I am. Dads can be so powerful and generous that way ...
Paradiso. (Dante) Paradiso (Italian: [paraˈdiːzo]; Italian for "Paradise" or "Heaven") is the third and final part of Dante 's Divine Comedy, following the Inferno and the Purgatorio. It is an allegory telling of Dante's journey through Heaven, guided by Beatrice, who symbolises theology.
