You will be surprised to learn that it is even easier to plan your vacation than you thought! But before you do, take some time to learn more about the Martian year and how it differs from the rest of the year.
Astronomers of Earth used the Roman calendar as the basis for the Martian calendar. The Martian year is divided into twelve months, the first nine months being made up of 56 sols and the last three of 55. The year begins on 1 March, the northward equinox. Other significant dates on the Martian calendar are the northern and southern solstices, as well as the perihelion and aphelion, which occur on 31 May and 31 November, respectively. Some believe that this was the first use of the Martian calendar in astronomical publications.
Mars’ elliptical orbit has important consequences. The planet’s southern spring and summer swings closer to the sun, thereby heating the atmosphere and sucking up fine dust and particles from the Martian soil. Dust storms on Mars are common during the second half of the Martian year and can sometimes become planet-wide. While this astronomical fact makes Mars’ year seem like a mystery, it is nonetheless fascinating.
In addition to this, Mars has four seasons. The northern hemisphere receives more sunlight than the southern hemisphere during summer. Therefore, the northern summer and winter seasons on Mars are longer than the southern ones. Mars has a slightly more elliptical orbit around the sun than Earth, so the seasons differ slightly. In general, the Martian year is longer than the Earth year. However, it is not entirely certain how the seasons on Mars change with the season.
There are many theories of the seasons on Mars, including the possibility of creating a calendar based on its lunar system. While the moon would have provided the calendar with a year-round cycle, Mars lacks a leisurely orbiting moon. As a result, there have been many imaginative calendar systems proposed to account for this. One such system divides Mars’ year into 12 months, each with its own distinctive seasonal events.
On Earth, seasons are defined by ecliptic longitude, with aphelion occurring on the summer solstice of the Northern Hemisphere. In addition, the seasons of Mars are based on solar longitude, or L sub s. The angle of the line between Mars and the Sun is zero at the vernal equinox, ninety degrees at summer solstice, and 270 degrees at winter solstice.
The Martian year is nearly twice as long as the Earth’s. Since the planet’s orbit is elliptical compared to the Earth’s, seasons are different in length and intensity. The northern hemisphere receives more sunlight during summer and less in winter. Mars also experiences aphelion and perihelion, the longest times of the year. And because of the tilt of the planet’s orbit, the northern and southern hemispheres experience different seasons.
Despite the differences between Earth’s seasons, Mars’ seasons are the most similar to Earth’s. As it is tilted about 25 degrees towards the Sun, Mars experiences similar temperatures. It is also tilted about the same way that the Earth is, so Mars experiences similar temperatures. Because the Martian seasons are longer than Earth’s, Mars has a higher amount of sunlight than Earth’s. This extra heat makes the surface temperature of the planet much hotter than its northern counterpart.
The Martian calendar has a unique quirk. Leap year occurs on odd years, and the last sol of Vrishika (February 29 in the Gregorian calendar) occurs only on such occasions. This is because the Martian year begins near the spring equinox in the northern hemisphere, and since Mars has a similar axial inclination to Earth, it is possible to discern seasons there. In addition, the orbital period of Mars is much more eccentric than the Earth’s, meaning that the last sol of the year is a leap sol.
Other planets also have leap years, but Mars’s system is particularly complex. While other planets have a standard leap year, Mars has two more than four. Mars has a solar year with 668 sols, but its calendar is so far behind that sometimes it needs to add a sol to catch up. That means that over the course of a 10-year period, it would have 4 668 sols years and six 669 sols years.
The Darian calendar was originally created by Tomas Gangale in the 1980s and includes 24 months. The first five months of each season have 28 days each, while the sixth month is seven days longer. The last month is a leap year, and the month of April is the only year that is not a leap year. This calendar is similar to the solar calendar, and Dr. Allison calls it a “whimsical exercise.”
The Mars year is divided into 12 equal intervals (56 sols) and a longer unit (month) called the aphelion. Both of these intervals are considered the same length, but the lunar calendar has a broader base. Thus, the lunar calendar’s aphelion coincides with the northern summer solstice. For purposes of comparison, a lunar calendar starts at Ls = 0 and ends at Ls = 270. The differences between these two calendars are so subtle that it is difficult to discern natural phenomena. In addition, calendars for Mars year use a different starting date than that of the traditional lunar year.
The date for the beginning of the Mars year is the same as that of the Gregorian calendar. A Gregorian calendar’s year number begins with A.D. and has a corresponding year number of BCE. Those wishing to know more about timekeeping on Mars can learn more about this new calendar. ESA has published some interesting facts on timekeeping on Mars. Here are some facts that will help you get started:
The first month in a Mars year is called March, and is derived from the Latin word martius, which means “of Mars.” As such, it is a fitting month name for the first month in a Mars calendar. However, the length of the months varies from calendar to calendar, depending on whether or not the algorithm of the leap year was used. When the lunar calendar is used, the last month on Mars is also called March.
Recent research shows dust storms on Mars may be caused by the extreme imbalance of energy a planet receives from the sun and releases as heat. University of Houston researchers, Liming Li, Xun Jiang, and Ellen Creecy, published their findings this week in the Proceedings of the National Academy of Sciences. They say the dust storms are the most likely cause of sand dunes on Mars. To see whether Mars is a potential habitable planet, we need to study its seasonal energy budget.
The orbit-spin coupling hypothesis suggests that Mars seasons are characterized by cyclical cycles of intensification and de-intensification. Moreover, these cycles are thought to be triggered by the phasing of angular momentum. These cycles could be coupled with Mars dust storms, which could explain the occurrence of global dust storms. For example, dust storms occur during Mars’ southern summer season.
Researchers have observed Mars’ dust storms for more than a century. The data came from the orbiting spacecraft and the Mars Global Surveyor. They studied the occurrence of large dust storms, or discrete dust events, on Mars. They have identified 65 dust storms within the Ls = 135-30 deg seasonal window. Scientists believe that Mars is able to host global dust storms multiple times per year.
NASA’s Viking and 2 spacecraft
The Mars year for NASA’s Viking and 2 is 2020. The Viking spacecraft landed on the planet’s northern equatorial region in April and will be followed by the Zhurong rover in 2021. During the 1970s, there were high hopes for the Viking missions, but the initial odds of landing were very low. Project manager Jim Martin estimated that only 75 percent of the Viking missions would be successful. The Viking project was one of the most challenging technological achievements of the twentieth century.
The Viking orbiters took almost 6,000 photographs each during their Mars year. They measured atmospheric opacity, and determined the average size of Martian aerosols. The Viking landers observed and analyzed radio signals from landers, which they could not see before. Viking was also the first to map 97 percent of the Martian surface. But Viking’s earliest photos may not be the best.
In the fall of 2017, scientists of NASA’s Viking and 2 spacecraft had mixed results. While the Viking lander did not find any evidence of organic life, scientists said it provided definitive analysis of Martian air. They also detected undetected trace elements in the Martian soil. Scientists were still deliberating the results of their experiments. However, they can only speculate that life exists on Mars, and they will continue to study the results.
