Space Tourism: A Synopsis on its Legal Challenges (1 Irish Law Journal 120, 2012) on SSRN. Here is the abstract:
Following Dennis Tito's flight to space aboard the Russian Soyuz capsule in 2001, suborbital has become a new form of commercial activity. Fueled by an eager public and decreasing prices, the industry is rapidly expanding. Because the current space law regime was originally designed for governmental exploration, it is inadequate to handle the range of legal challenges emerging from this private commercial activity. This article therefore suggests that the current legal regime is incapable of sustaining the space tourism industry and that there is an urgent need for a new international convention.
