  • How do I uninstall Eyes from my computer?

    For a Mac, Eyes is located in your Applications folder. You can drag the "NASA's Eyes" application to the trash to remove it from your system.

    For a PC using Windows 7, 8, or 10, the program does not show up in the normal "Add/Remove Programs" feature.  There is a custom uninstaller located in the Users folder.  It will be similar to this path:  "C:\Users\YourUsername\AppData\Roaming\JPL-NASA-Caltech\NASA's Eyes\Uninstall.exe"

  • When I start the program, it gets stuck at "Downloading" or says "Initialization Failed."

    This may occur if you are behind a proxy server. Unfortunately Eyes does not currently support proxy servers, although it is planned for the future.

  • When I start the program on OSX 10.14+, I get an error similar to "Not authorized to send Apple events to Finder (or System Events)."

    This may occur if you have previously denied permission to NASA's Eyes to access the Finder or System Events, which is used to implement an auto-upgrade system and to link eyes:// URLs to the application. To fix this, go to System Preferences → Security & Privacy → Privacy tab → Automation, and find NASA's Eyes in the list. Make sure the two boxes for Finder and System Events are checked. Start NASA's Eyes and the error message should be gone.

  • When I start the program on OSX 10.15+, I get an error similar to "NASA's Eyes can't be opened because Apple cannot check it for malicious software.";

    In OSX 10.15, Apple has restricted valid apps to only those validated by its certification process, and NASA's Eyes does not use that certification process. To fix this, after you have seen the message, go to System Preferences → Security & Privacy → Privacy tab → General, and see the message "NASA's Eyes was blocked from use because it is not from an identified developer" at the bottom of the window. Choose "Open Anyway", and then in the popup choose "Open".

    You may also be prompted with these popup messages: "NASA's Eyes wants access to control Finder or System Events". Choose "OK". NASA's Eyes should start after this.

  • When I start the program on OSX 10.15+, I get an message similar to "NASA's Eyes would like to receive keystrokes from any application.";

    In OSX 10.15, Apple notifies the user when an app needs access to raw keystrokes. NASA's Eyes runs on the Unity game engine, which accesses the raw input events, as most game engines do. Accessing raw input events means that the engine has access to all input, even when in the background, resulting in this message.

    NASA's Eyes does not use that feature and will work fine if you choose "Deny".

  • How can I view the logs?

    When things go wrong, you want to know why. They can also help JPL diagnose what the problem is. Here are the locations for the logs:

    The launcher's log is at C:\Users\{username}\AppData\Roaming\JPL-NASA-Caltech\NASA's Eyes\install.log
    The application's log is at C:\Users\{username}\AppData\Roaming\JPL-NASA-Caltech\NASA's Eyes\explorer-win_Data\output_log.txt (it may be explorer-win64_Data if you have a 64-bit version).

    The launcher's log is at "/Users/<username>/Library/Logs/NASA's Eyes Launcher.log"
    The application's log is at "/Users/<username>/Library/Logs/Unity/Player.log"

    You can also send us the logs to help us help you diagnose any problem you have.

  • What are the system requirements to run Eyes products?

    Windows 7+, and Mac OSX 10.8+

  • Where is the Linux version?

    The Eyes family of products was developed on the Unity game engine.  The development process took years, and Unity was not available on Linux until recently.  We hope to port the program to Linux in the near future. 

    In addition, web versions of Eyes are in development and will work on any web browser on Linux. 

    The first available web version is Eyes on Exoplanets, available here:

  • Do the Eyes products work on my phone or tablet?

    Eyes on the Solar System and Eyes on the Earth only work on desktops and laptops at this time.  We are developing a version for mobile devices and tablets. 

    Eyes on Exoplanets is now available for any device with a web browser:

    DSN Now and Experience Curiosity already work on your phone or tablet using your web browser.
