Discovery's upward thrust at lift-off came from a solid mixture of ammonium perchlorate and aluminum metal, along with an iron oxide catalyst to speed the burning reaction along, and a "binder" material to hold all the components together. Seventy-five seconds after separation the boosters reach their highest altitude (about 41 miles) and begin to fall back to Earth. Aluminum reacts rapidly with ammonium perchlorate, NH 4 ClO 4.. Let's look at the reaction and then write a balanced equation. (This does not happen to the solid rocket boosters because they never leave the atmosphere. Oxygen from ammonium perchlorate combines with aluminum metal to produce aluminum oxide--the white solid Al2O3-- and aluminum chloride, AlCl3, water vapor and nitrogen gas. Manufacture of ammonium perchlorate began in the 1940s, primarily for use by the defense industry and later by the aerospace industry. List some of the risks and benefits of the space shuttle program. Science Education For Public Understanding and According to a recent report, perchlorate is present in the environment in 35 states, showing up at low levels in groundwater and in certain public water supplies and food sources. Solid rocket boosters are equipped with flotation devices, radio signals and lights so they can be located and towed back to Florida by ship for reuse. Introduce, either ammonium or potassium chloride in the solution and the corresponding salt will precipitate out as their solubility is very low compared to sodium perchlorate. Its instability has involved it in a number of accidents, such as the PEPCON disaster. 6. Chemistry, of course, plays a major role in space exploration, and the chlorine compound ammonium perchlorate, NH4ClO4, helps to launch space shuttles like Discovery by providing the thrust needed for lift-off at a point in time when the shuttle is at its heaviest.
