Mars Clock

By SunlightAndTime

This app is only available on the App Store for iOS devices.


Use your iPad, iPhone, or iPod Touch to display "Mars time", the timekeeping system that NASA scientists use to monitor the activity of Mars Rovers. NASA's newest Mars Rover Curiosity was launched on November 26, 2011 and landed on Mars on August 5, 2012.

Mars Clock is an iPad/iPhone/iPod utility that displays accurate local Mars time at the Curiosity landing site. Sunrise and sunset times are also displayed so that daylight hours, when the Rover is most active, can be determined.

-Local mean solar time for Mars Curiosity Rover
-Coordinated Mars Time
-Sunrise/sunset times for Curiosity landing site.
-Current Martian season
-Curiosity Mission Sol (Martian Days since landing date)
-Utility to convert a Martian Sol to an Earth Date, or an Earth Date to a Sol
-Current Earth-Mars distance
-Current Earth-Mars communication delay
-Earth Time (local time and UTC)

Mars Clock is a Universal App designed for the iPad with the same functionality on both the iPad and iPhone. The only thing missing on the iPhone app is information about, and a large image of, the Curiosity Rover.

What's New in Version 1.3

This version not compatible with iOS 11. We are currently working to update the app as soon as possible.

*** Corrected a bug that caused an error in the Mars Sol displays for devices using iOS 6. We apologize for any inconvenience as a result of the error.

i bought this to see converting the dates of mars and earth but it wasn't displaying. You need to fix this, also it would be nice if there was the Darian Calendar.
