Hi,
I have several of these. The ablation and flow lines are interesting, especially in the plugs, and well worth having for comparative purposes. However, the flow lines are in a resin coating of the plug (which is very light weight), not in metal. Re-entry speeds of artificial satellites are much lower than those of meteorites so we shouldn't expect the massive ablation that the latter experience.
I am told that the Chinese simply use wood as a re-entry shield. Would be fun to get ahold of some of this. But how would we know it is authentic?
Cheers, Nick

Hello list,
Possibly of interest to some is these photographs of a "heat shield" from a flown Soyuz spacecraft capsule. I was hoping it would compare more with the heat shield shaped meteorites I have. However, this item is pretty much just a scorched piece of heat resistant metal attached to a wood block and fiberglass put on the inside side. If you are interested you can view photographs of the disc shaped item at the following link:

The other day I brought the Rubicon 1 rocket home from the dock. Without its engines and stripped it still weighs over 300 pounds. This large object fell out of the sky last August into the Pacific ocean....shortly after takeoff. Not a meteorite of course, but it was a big piece of metal that fell from the sky. I learned a valuable lesson we should all memorize the day I brought space capsule and nose cone home. Space rockets do not fit through doorways. Sorry, no "recovery" photographs as it was raining last week when I moved the item to where it is now. I will try to take some photographs of the wreckage later. The nose cone pieces are each about the size of me.
