    I suspect that JPL will provide ephemeris data via its Horizons web page:
    To find a spacecraft of interest, click "Target Body", select "Spacecraft" from the drop-down list, and hit the "Display
    List" button.
    I did not see Mars Observer in the list, but perhaps it will appear closer to the departure date.
