Launch vehicle dynamics,t of space on many aspects of science, commerce, and daily life is possible. The launch lasts only a few minutes, and yet during this short period of time, many years of development and investment in the commercial use of the spacecraft can be brought to nothing if just one of the many thousands of

Electric propulsion, generating thrust. There is an elegant simplicity in this triple function of the propellant and its combustion products, which is reflected in the simple nature of the rocket engine. There is, however, a fundamental limitation which results from combining the functions of working fluid and energy s

Advanced thermal rockets,as of space activity—such as communications and Earth observation—are justifiable for economic or strategic reasons, while others—such as pure science, human exploration, or even tourism—have a weaker position. If space is to become a routine environment for human activity, either manned or unmanned

Human space flight and planetary exploration,e design of a safe launcher and a safe return system, and the design of safe soft-landing systems for planetary and lunar surfaces. Sadly, we have examples of both launch and return tragedies, the result of a design that was not robust against all the exigencies of an active human space flight progr

The thermal rocket engine,hapter we shall treat the rocket motor as a heat engine, and examine the physical principles of its operation. From these physical principles the strengths and limitations of rocket motors can be understood and appreciated.
