    I am planning to observe and videotape the MIR reentry in the Southwest Pacific in late February and would appreciate any information on the Pacific ocean impact footprint that anyone has (or any sources where I might find more information on the details of the deorbit trajectory of MIR.)  The following was the information in the news media this morning.
      
    "MIR's organized re-entry into the Earth's atmosphere will take place around the 26th, 27th or 28th of February, with the main fragments of the station falling into the Pacific Ocean between 900 and 1,200 miles from Australia."  Anatoly Kiselyov, head of the Khrunichev center that designed and built Mir, said ballistic experts reckoned parts of the vehicle would hit an area up to 6,250 miles long and 125 miles wide, Interfax reported. He said there was no way to guarantee that all sections would fall safely into the ocean. "To calculate precisely the mathematical model of the process...of passing through the atmosphere and falling into the ocean of a 130-ton multi-module orbital complex with enormous paneling is not feasible," Kiselyov said. Koptev said that on re-entry, Mir would break up into thousands of fragments, some weighing as much as 1,500 lbs. They would hurtle toward Earth with enough force to smash a way through reinforced concrete six feet thick.
