You can find them on eBay just search for "24 hour" clock (with quotes around "24 hour"). If you use one of these and slow it down for Mars time, you will then have a clock showing Mars hours, minutes, and seconds. Second: There do exist (somewhat) reasonably priced analog 24-hour clocks, for Earth time. This is what I had to do for a clock for my apartment: There are some points I would like to make:įirst: I am glad people are taking the initiative to do something instead of just wringing their hands and lamenting the lack of an existing product. This is the first piece of code I'm messing with (terribly inefficient) and start again adding 1 digit every 1027 milliseconds. I thought since you can write a delay based on milliseconds you might be able to write a digit 000,000(plus one) at a delay rate of 1027-1028 until you reach 243,935 at which point the program would return to start at 000,000. The difference in time between seconds on Mars and Earth is (Earth 1.0274912510416665 second = Mars 1 second) so my idea was to simplify the code and make the watches extremely low cost and easy to reproduce. I had hoped to stay under the pricing and complicated programming/workmanship they had to input ($50-$400 price points). or_JPL.php ).Īnd an engineering student made a digital one (. I looked around to see if anybody else had made one and it turns out a jeweler made a mechanical one for JPL (. I've been thinking about making a super simple Mars watch. The links below will take you even farther into the future.I'm glad I found this forum. It also shows the time most of us use today: - LOCAL: Your device’s local time.OK - You’re all set to imagine yourself in an exciting new future - and pretty well prepared to jump into an historic debate. The application shows the official times of both planets: - MTC: Mars' official time, called Coordinated Mars Time (MTC) (also known as Airy time), - UTC: Earth's official time, called Coordinated Universal Time (UTC). The Kepler calendar uses the same structure as the Darian calendar but names the months and sols differently, and does not skip over a sol during months 6, 12 and 18 like the Darian calendar.TIME DISPLAYS: To FaceTime your kids without waking them, you’ll need to know the time on Mars as well as on Earth. For example, Thomas Gangale created the Darian calendar with a structure of 24 months of mostly 28 sols per month (there are four with only 27 sols, but in leap years this goes down to 3). Many different calendar structures have been proposed over the last century, with different characteristics. CALENDAR: The Mars year is 668.5907 sols long, so a year in a Mars calendar will typically contain either 668 sols or 669 sols (if it is a leap year). Likewise, for Mars there is a Mars Sol Date (MSD) which is a count of sols from a specific epoch. For example, the Julian Day Number for Januis 2,451,545. For convenience, timekeeping on Mars assumes that a sol is exactly 24 hours long, just like on Earth, except that each time unit on Mars is 2.7% longer than on Earth.EPOCH: Astronomers keep track of a count of days for Earth called the Julian Day Number - which is just a count of days from a specific date in history called an epoch. And, while the debate is converging on some solutions - it’s far from finished! Check out the settings below so you can participate in this historic debate - it isn’t every generation who gets to literally shape time!SOL: A day on Mars is called a sol, and is about 2.7% longer than a day on Earth, at about 24 hours, 39 minutes and 35.24409 seconds long. Scientists have been debating how best to keep track of time and days on Mars for the past century. Calendar DatesStraightforward, right? Not so much. This app will help you start thinking like a future Terran with ties to a Mars colony. There is a good chance this could happen in your lifetime - or at least in the lifetime of your kids or grandkids. You are probably middle-aged (because life expectancy has grown) and one or more of your kids may be preparing to leave for a colony on Mars. The application shows the calendar date for Coordinated Mars Time (MTC) and Coordinated Universal Time (UTC) as well as your device’s Local Time (Local), with the ability to select between some popular calendars proposed for Mars.Martian Calendar InformationFast Forward About 75 Years.
