This paper is presenting analyses of legitimacy of incurring high costs of sub-orbital, orbital and space flights in the context of the possibility of allocating them to leveling and reducing the current problems of humanity on Earth. There are a lot of questions and doubts about reasons of spending a lot of money for space traveling where in the same time we have a lot of not resolved problems on the Earth. So maybe instead of covering costs for space traveling we should dedicate them for improving people life on our planet. How does tourism fit with the underlying philosophy of space law: that the exploration and use of outer space “shall be carried out for the benefit and in the interests of all countries”? Given the cost associated with space exploration, one naturally has to ask what the benefits are and whether they are worth it. This paper is analyzing pros and cons sub-orbital, orbital and space flights from the social, commercial, technological and political point of view.
