I was wondering what it is made of exactly and if there are different ways of making it. Also what the process of making it is. Ha! No I'm not trying to take over the world. Just wondering. Thanks.

a Nasa site I don't remember said:"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."
The flexibility of nitrous oxide as an oxidizer is stunning. Not only is it self-pressurizing, but it can be used on a variety of fuels, such as asphalt and polyvinyl-chloride.LURCH said:I remember the pilot of Scaled Composit's X-Prize winner, "Spaceship One" quipping that he was going into space riding on "tire rubber and laughing gas". Their choice for solid fuel was a mixture of the main polymer used in automotive tires and nitrus oxide.
