Developing School Leaders in the Pacifice ideas are discussed along with how we can best think about technological extrapolation into the future – by accepting changes in established paradigms and then considering the implications to our current technological development.

Aviation: The Pursuit of Speed, Distance, Altitude, and Height,itial foundation for how thrust is generated. By attempting the problems at the end of this chapter we learn about the limits of jet propulsion technology in reaching high altitudes, and the requirement for rocket engines will be much clearer.

Towards Relativistic Propulsion: Antimatter and the Interstellar Ramjet,ty that will be discussed. We then discuss two schemes, which may have the potential to actually approach the speed of light limit, and although they may seem speculative today they could form an important part of tomorrow’s space faring civilization.

Book 2012ven observe some of the recently discovered planets circling these stars. This book looks at the reasons for exploring our stellar neighbors and at the technologies we are developing to build space probes that can traverse the enormous distances between the stars..In order to reach the nearest stars

ms.Separates the realistic from the fantastic and makes clea.The technology of the next few decades could possibly allow us to explore with robotic probes the closest stars outside our Solar System, and maybe even observe some of the recently discovered planets circling these stars. This book looks
