FEASIBILITY STUDY OF HIGH ALTITUDE ATMOSPHERIC LAUNCHERS TO ORBIT by Anna Rapo This thesis addresses the topic of launching an aerospace vehicle to orbit from a high altitude. The current transportation system from Earth to space has been deemed by many to be expensive, unreliable, and an unnecessarily dangerous means of travel to space. It is suggested in this proposal to examine a different type of launch from a high altitude to an orbit in space. By lifting the vehicle to a high altitude within Earth's atmosphere using a high-altitude balloon followed by the activation of the vehicle's propulsion system, a potentially cheaper and safer, though obviously longer journey, could be achieved to space. ACKNOWLEDGEMENTS To my mom and sister for being patient throughout both of my degrees, and taking me out running to freshen up those precious grey cells. To my brothers whose support I felt even from thousands of miles away. To my husband, I could not have accomplished all this without your love, and encouragement throughout the hard parts. To my advisors for their wisdom and knowledge and to whom this work is largely due.
