    NOTE: subject change since we appear to be talking about stellarium now... 
    should this also be marked OT??

    latest list of what? note also that not all satellites are set to be visible 
    even though they are taking up processing time and memory space...
    have you added all the ones you want via the satellite management window? that's 
    on the far right tab (IIRC) where you tell it to download the lists and present 
    the satellites for you to go thru to select those you want to add to the JSON

    you have to either edit the JSON file directly by copying an existing record 
    (and don't mess up the format by leaving out a comma or putting a comma in the 
    wrong place) and changing the norad number... then you update and it should 
    place the proper TLE data in that newly created record... or you can add your 
    TLE file as an additional one in the list of files be used by stellarium...
    everything that can be done from within stellarium is done within the satellite 
    module's configuration/management window... anything else satellite related must 
    done directly to the JSON file while stellarium is not running... i use 
    notepad++ on windows to also ensure that i do not get the wrong end of line 
    characters in the files because that will break things, too...

    create your TLE in a TLE file using the three line format... then tell 
    stellarium to use it... there are tabs in the satellite management window that 
    you switch to for altering what files are pulled from where... you can also tell 
    it to use local files instead of downloading them from some web site... i do not 
    recall if you can use downloaded and local files at the same time, though...
