Fw: [meteorite-list] Anomolous Aluminum Object's..

[Sterling K. Webb]

 Thank You sterling!!..That may be just what they are!..Zephyrhills is due 
west of Cape Canaveral..Been there..used to watch the liftoff's from our 
house..and the highest hill in town!..And indeed if that's what they 
are?..they would be a cool souvenir!
Will this reply go to the list?..Kevin w.Decker.

Hi, Kevin,

    Now that you tell me that they are composed of
aluminum particles and since I looked up Zephyrhills
on a map, I suggest that they are from the solid rocket
boosters for the Shuttle.

    From NASA's web site:
The propellant mixture in each SRB motor consists of an ammonium perchlorate 
(oxidizer, 69.6 percent by weight), aluminum (fuel, 16 percent), iron oxide 
(a catalyst, 0.4 percent), a polymer (a binder that holds the mixture 
together, 12.04 percent), and an epoxy curing agent (1.96 percent). The 
propellant is an 11-point star- shaped perforation in the forward motor 
segment and a double- truncated- cone perforation in each of the aft 
segments and aft closure. This configuration provides high thrust at 
ignition and then reduces the thrust by approximately a third 50 seconds 
after lift-off to prevent overstressing the vehicle during maximum dynamic 
pressure.

    And of course they would be melted and have traveled
at a high speed and all the rest of it. If that's what they are,
they make a pretty neat souvenir, even if they aren't tektites!
