Space tourism might be one of the industries that target at smallest segments of consumers. Up to date, only 7 tourists all over the world have been to the space. Apparently, space tourism companies use a highly concentrated segmentation strategy. In my opinion, this concentrated strategy is reasonable since the segement consumers are very profitable and attractive despise the fact that there are not many of them.
Here are some of the segmentation variables for space travellers that I come up with.
Geographic segmentation: Mainly North America.
Demographic segmentation: Extremely high income, most male
Psychographic segmentation: risk-loving people (self image) with adventrous life style
Benefit segmentation: People who seek the benefit of exploring the nature and looking for thrills in their lives.
Although space tourism is traditionally characterized as high-end and not reachable for ordinary people, space trip providers now began to reposition themselves recently. Several year ago, it might take travellers millions of dollars to travel in space, but now some companies offer a low price of $100,000(still seems really expensive to me). I think the reason for repositioning is to gain more popularity and reach out to a wider base of customers.
