The LROC Team Release of JMoon is available to members of the LROC mission operations and science teams for use in planning and analyzing observations made by the Lunar Reconnaissance Orbiter Camera (LROC) aboard the Lunar Reconnaissance Orbiter.

In addition to the standard layers available in the Public Release, the Team Release includes the LROC ROI Layer, LROC Stamp Layer, and the LROC Planning Layer. The Team Release also gives science team members access to LROC data that has not yet been released officially through the Planetary Data System (PDS).

The Team Release version of JMoon is currently available only within the LROC Science Operations Center building at ASU.

A public version is available through JMARS, with access to only the PDS-released products, is available through the JMARS download page. To change from the Mars body to the Moon, open JMARS : Go to the top of JMARS window and click "Body"--> "Select Body" --> "Luna".

      1. Please contact one of the mission planners.
  2. Public Users
    1. Internal Users
      1. In the Mars Space Flight Facility building, open a terminal on a Linux machine and type:
      2. > jmars -moon

    2. External Users
      1. On most operating systems, the installer will place an icon on your desktop. You can start JMARS/JMoon by double-clicking the icon and entering your username and password.
      2. To manually launch JMARS/JMoon on a Linux machine, change to the directory containing the jmars.jar file (which you have already downloaded) and type:
      3. > java -jar jmars.jar

        • If you would like to open JMARS/JMoon from a different directory, just replace "jmars.jar" with "path/jmars.jar".

Starting JMARS/JMoon with additional arguments

The startup behavior of JMARS/JMoon can be modified by including additional command-line arguments. (Note: Only one of these command-line arguments can be used at a time.)

  1. Specify the Starting Position
  2. By default, JMARS/JMoon starts with the viewing window centered at 0E, 0N. This starting location can be changed by adding latitude and longitude arguments to the jmars command.

    > jmars Longitude Latitude

    • Longitude - the value is assumed to be East longitude unless a "W" is used after the numerical value. (e.g., 120W)
    • Latitude - the value is assumed to be North latitude unless a "S" is used after the numerical value. (e.g., 120S
  1. Starting with Session Files
  2. Session files allow users to restart JMARS/JMoon in a previously saved configuration by specifying a startup file. See the Session Files page for more information.

>jmars path/session_file_name.jmars 


Starting JMARS/JMoon with flags

The startup behavior of JMARS/JMoon can also be modified by including any of the following command-line flags. Unlike the command-line arguments described above, multiple command-line flags can be used at one time, and they can be used in conjunction with command-line arguments.

  1. Clean: The "clean" flag will clear out the map tile cache before startup.
  2. > jmars clean

  3. Slideshow: The "slideshow" flag will enable the JMARS/JMoon slideshow mode. See the Slideshow Mode page for more information
  4. > jmars slideshow

  5. Version: The "-version" flag (with lower case v) will list some information about the JMARS/JMoon version being used. The "-Version" flag (with upper case V) will list much more detailed information about the JMARS/JMoon version being used.
  6. >jmars -version

    >jmars -Version

  7. Help: The "-help" flag will list the available command-line arguments and flags in the terminal window.
  8. >jmars -help
