A propulsion system for use with a satellite comprises a substrate, a communication network and a cluster of individually selectable solid fuel motors mounted on the substrate and operatively connected to the communication network. A controller is also operatively connected to the communication network and operative to select any one of more motors of the cluster of individually selectable solid fuel motors and transmit signals to fire the one or more motors of the individually selectable solid fuel motors. The substrate may have various configurations. The cluster of motors may comprise 10-1000 motors, which may be arranged in a rectangular array or other formation. Subsets of motors having different impulse capabilities may be employed. In this manner, lighter, smaller, flexible and more efficient propulsions systems may be provided for use in attitude control, etc. of satellites.

Embodiments of materials suitable for use as a replacement for Tetrazene and methods of preparing such materials are described. In one embodiment, the material comprises MTX-1, as well as simple salts or complexes derived therefrom. The methods of preparing such materials include combining Tetrazene and an acid to form a suspension, where the acid is nitric acid, sulfuric acid, perchloric acid, or hydrochloric acid. A nitrite salt may be added to the suspension, where the nitrite salt is sodium nitrite, lithium nitrite, potassium nitrite, an aqueous solution of sodium nitrite, an aqueous solution of lithium nitrite, or an aqueous solution of potassium nitrite. In some embodiments, the suspension is stirred until the suspension has a white appearance.
