Luckily, researchers have encountered the secret to resting well on Mars: having a long circadian rhythm. ![]() #Mars24 time clock how toA seemingly less considered hurdle will be learning how to sleep on the red planet - and that in and of itself could make or break a mission. They’ll need to learn to cultivate Martian dirt, come to grips with the fact they’re probably not going home, and figure out a sexual situation. An excellent JAVAscript implementation of the MARS24 calculationsĬhangelog 0.9 - Initial public release to Google Play.The first human colonists on Mars will have to undergo some major adjustments. A thorough explanation of how to tell the time on Mars This application is based on the calculations explained within the worked examples from this site the definitive Mars clock, as produced by NASA. A now defunct Rover that landed on Mars in January 2004. Spirit Rover - Mars Exploration Rover A (MER-A). This equates to just under 24 hours and 40 minutes in Earth time (so a Martian sol is just under 3 percent longer than an Earth day). A currently active Rover that landed on Mars in January 2004. Opportunity Rover - Mars Exploration Rover B (MER-B). MTC - the time zone based on the Local Mean Solar Time at the Mars Prime Meridian (previously referred to as Airy Mean Time). ![]() It is effectively the Mars equivalent of the MJD. This is a count of the number of Sols since the Earth date of 29th December, 1873. This is simply a cumulative day count, often used by astronomers, etc. The count of Earth days since 1st January, 1970. When mission clock is selected in this application for a given rover the Sol count is shown - this is a reflection of the number of days that the rover has been on Mars (oddly, some missions count Sol 1 as the landing day, while others count Sol 0 as the landing day). The mission clock is what is used by the Rover\’s handlers back here on Earth to plan mission events. That\’s why, for each rover for example, the mission clock does not exactly match the LMST for the landing coordinates. For various reasons these longitudes do not tend to map directly onto specific mission landing coordinates, but instead the offsets are from MTC. The majority of these have been based on offsets of LMST for a given longitude on Mars. Instead of using a standard time zone to measure time at each landing site, each mission so far has used its own unique mission time. Mission Clock - The mission clock relates to each specific Martian Rover or Lander mission. Martian Time Zones - Each Martian time zone covers 15 degrees of longitude, and is referred by an offset to MTC, e.g. It is defined as the centre of the Airy-0 crater. The point by which all other Mars longitudes are measured. The time based on the true position of the Sun for a given longitude. An areocentric longitude of 0 degrees relates to the Mars Northern hemisphere vernal equinox (on Earth in the Northern latitudes we would refer to the Earth equivalent of this as the spring equinox). Rather than describe the time of the Mars year by the use of month names, or seasons, the areocentric longitude is used instead. A Mars year lasts just under 687 Earth days. The local mean solar time for a given time zone. The time based on a mean sun position - akin to using something like GMT on Earth. A currently active Rover that landed on Mars in August 2012. The centre of Airy-0 is used to define the Mars Prime Meridian.Ĭuriosity Rover - the Mars Science Laboratory (MSL). A crater roughly 500 meters in diameter that sits inside the larger Airy crater. However, as a Martian Sol is longer than an Earth day, each Martian hour (and minute, and second) is roughly 3 percent longer than its Earth equivalent. A Martian day, or Sol, consists of 24 Martian hours, each divided into 60 Martian minutes, which in turn are each divided into 60 Martian seconds. ![]()
