Space Tourism
Space Tourism is the term that’s come to be used to mean ordinary members of the public buying tickets to travel to space and back. Many people find this idea futuristic. But over the past few years a growing volume of professional work has been done on the subject, and it’s now clear that setting up commercial space tourism services is a realistic target for business today.
The first steps will just be short sub-orbital flights, like Alan Shepard made in 1961, since these are easier than getting to orbit. But the technical know-how to make passenger launch vehicles and orbiting hotel accommodation is available, and there is enormous unsatisfied demand — market research has revealed that most people, at least in the industrialized countries, would like to take a trip to space if it was possible. This gives huge scope for reducing the cost of space travel by large-scale operation like airlines.
The main obstacle is simply the conservatism of the space industry as it is today. Since Sputnik was launched in 1957 most space activities have been funded by governments.
And this "cold war" pattern of space activities has created an image of space that colors everyone’s thinking about it — writers, journalists, politicians, scientists and engineers, and the general public. Even science fiction writers assume as obvious that most space activities will always be government activities.
Like any other business, once space tourism gets started it will develop progressively. It can be helpful to think of it as going through several phases. Starting with a relatively small-scale and relatively high-priced "pioneering phase" , the scale of activity will grow and prices will fall as it matures. Finally it will become a mass-market business, like aviation today.
