Demonstrates the use of FreeFlyer to model an orbital debris field caused by the collision between the Cosmos 2251 and Iridium 33 satellites on 10 Feb 2009. The debris field is generated by applying a Gaussian distribution of delta-V to the velocity components of each debris object. The field is propagated for a few orbits to show dispersion. The ISS orbit is shown for reference, as are the remnants of the debris generated by the destruction of Fengyun 1C in 2007. Fengyun debris, Cosmos, Iridium and the ISS are initialized using TLEs.
