Encyclopedia of Monopropellants is the only book ever published that is exclusively devoted to monopropellants. While not using the highest performance rocket propellants, monopropellant rocket propulsion systems are unique in their simplicity and reliability. The energy content of monopropellants is limited by their ability to detonate, requiring thorough safety property testing before declaring a new monopropellant safe for flight use. Spectators and TV watchers never get to see monopropellants in action, but monopropellants always perform their tasks behind the scene of spectacular space vehicle launches.
