Efforts are currently under way to place man into orbit on a semi-permanent basis through use of a space station. At the same time,the aerospace industry worldwide is considering the extension from supersonic flight of advanced fighter aircraft to the hypersonic flight of a future aerospace plane. To meet the challenges of the many technical problems to be solved in this new area, the Flight Mechanics Panel sponsored its first symposium on Space Vehicle Flight Mechanics, held in Luxembourg, from Nov 13 to 16, 1989. Its purpose was to examine the flight mechanics of vehicles in space and in the upper layer of the atmosphere and to identify the areas of technology relevant to the Flight Mechanics Panel. This technical evaluation report evaluates the presentations and discussions in each of the five sessions of the symposium. 收起
