Hi all, I have been working orbit mechanics for a communications experiment for about 2 years now. With all the interest in MIR and reentry, I got to wondering if it was possible to model the reentry process, complete with retro burn and splat. Well, I took my existing orbital code and added the necessary components and it appears to work. I can now simulate a ballistic reentry and the motion post-impact. I have posted a page and some animations which can be found at the following URL: http://www.d3experiment.homepage.com/MIRDeorbit I am interested in obtaining more information on the expected day of the deorbit. If anyone has the current plans perhaps you could follow-post them. I have done some searching but couldn't find anything more than CNN updates. What I would like to do is update the initiation vector as time goes on and then reissue the simulation to get new ballistic trajectories. One item as indicated in the above link, it is not very easy to get a controlled deorbit, i.e. too much retro and it falls out fast, too little and you miss the hoop. Of course, I am a beginner at deorbiting LEO sats so if anyone else has applied experience I would be happy to get a few pointers. All feedback is welcome.
