Space tourism - A promising future?

Based on presentations made at the first International Symposium on Space Tourism (ISST), held in Bremen on March 20–22 1997, an overview over the current state of discussion on space tourism is given. Starting with an evaluation of the current situation for spaceflight, the author's viewpoint on the rationale for space tourism is described. The potential of space tourism as a future large space market is demonstrated using the results of recent market research and projection. This is followed by discussion of the appropriate technical means for space tourism in terms of space transportation systems and orbital infra-structure. In addition, the necessary non-technical boundary conditions to initiate space tourism and the associated dangers and risks are described and assessed
