    Rosaviacosmos, the Russian Aeronautics and Space Agency, predicts that 
    the Russian Space Station Mir will make its final fiery ride to Earth tomorrow.
    The 130-ton station is the largest structure ever to be dropped from orbit.
    To ensure that it drops properly and breaks up in the Earth's atmosphere,
    representatives from Analytical Graphics (AGI) - a Malvern, PA-based
    analysis and visualization software provider - are in Moscow working with
    Russian officials to simulate deorbit.
    AGI's Flight Services team is working with TsNIIMash, a Russian institute
    associated with the Russian space agency, to provide situational awareness
    of events during the deorbit. AGI's Satellite Tool Kit(r) is using
    spacecraft position and orientation data, as well as timed events such as
    thruster firings, to create detailed, analytically accurate 3D graphics.
    The images will be projected in the Russian mission control center and will
    show Mir as it moves along its flight path toward its eventual break-up.
    In June of last year, AGI assisted in the re-entry of NASA's Compton Gamma
    Ray Observatory, which, like Mir, was too large to burn up entirely in the
    atmosphere as it fell to Earth. NASA used Satellite Tool Kit to plan a
    safe re-entry trajectory.

    re-entry, visit .
