Earlier, I blogged about the collision between Iridium 33 and the defunct COSMOS 2251 satellite. Today, I noticed that Celestrak had orbital elements for 134 fragments resulting from the collision. I was curious what the resulting pattern would look like, so I wrote a bit of code to suck them all in and plot them on a map. Here’s what I got for a particular moment around noon local time.
The labeled points are the tracked location of the main body of the satellite. There are orbital elements for 48 additional fragments of Iridium, and 84 additional fragments of COSMOS. The main body of Iridium 33 was at 785km altitude, while Cosmos is down around 771km. Debris is scattered over quite a wide variety of altitudes, from a low of 284km to a high of 1158km.
