Download Mars24

The current version of Mars24 is 7.1.1, released 2015-12-30.

Mars24 requires a computer with a Java SE 7 or 8 runtime environment installed.

Installing Mars24 on Mac OS X

The Mars24 package for Mac OS X comes as a DMG disk image which can be mounted by doubleclicking on the Mars24OSX.dmg desktop icon. Then just drag the Mars24 folder within to your Application folder.

The folder holds the following items:

  • Mars24 application.
  • Martian landmarks file "marslandmarks.xml".
  • "Sourcemaps" directory containing extra sample Mars maps.
  • A README file.
  • A subdirectory called "help" which includes user documentation.

To run Mars24 on Mac OS X, just double-click on the Mars24 application.

Installing Mars24 on Windows

The Mars24 package for Windows comes as a ZIP archive. You must manually extract this archive. Some versions of Windows allow you to run programs from a zipped archive without extraction, but if you try that with Mars24, it won't work.

The Mars24 archive contains a folder called Mars24J which holds the following items:

  • Mars24.exe application.
  • Martian landmarks file "marslandmarks.xml".
  • "Jars" directory containing program code.
  • "Sourcemaps" directory containing extra sample Mars maps.
  • A README file.
  • A subdirectory called "help" which includes user documentation.

To run Mars24, double-click on the Mars24.exe application icon.

Debugging Installation Problems:
If you find that after download and installation, Mars24 for Windows won't start, a possible reason might be that you don't have a Java Runtime Engine (JRE) installed on your computer. Go to the Java.com website and click on the "Free Download" button.

Note: It is possible to have a Java plugin enabled in your web browser which allows you to run applets, but not have a JRE installed which allows you to run Java applications.

Installing Mars24 "Generic" on Linux, etc.

The Mars24 "Generic" package is for computers not running the Mac OS X or Windows operating system.

Depending on your operating system and how you have it set up, installing Mars24 may be as simple as double-clicking the Mars24J archive icon on your desktop. If not, then you may have to use the appropriate command-line call from the shell.

The Mars24 archive contains a folder called Mars24J which holds the following items:

  • Java application in a jar file called "Mars24.jar".
  • Other Java code in additional *.jar files.
  • Martian landmarks file "marslandmarks.xml".
  • "Sourcemaps" directory containing extra sample Mars maps.
  • A README file.
  • A subdirectory called "help" which includes user documentation.

Depending on your operating system set-up, you should be able to launch Mars24 by simply double-clicking on the Mars24.jar file. But if that desn't work, then you would need to launch from a shell command line by typing:

    java -jar -Xmx512M Mars24.jar
