The 2nd International Symposium on Space Tourism took place in Bremen from April 21-23, organised by Professor Uwe Apel of Bremen Technical University as Chair of the Program Committee, and Hartmut Mueller of Space Tours Gmbh as Chair of the Host Committee. Among the 26 papers presented, several are destined to become recognised as 'classic' papers in the field, establishing an important new element of accepted wisdom among professionals in the field, or creating what will be seen as a milestone in the future.

Over the past few weeks, two self-made billionaire businessmen have established companies with the stated objective of playing roles in the commercial space tourism industry that is becoming increasingly widely recognised as the true future of space activities.
