The development of space tourism plays a significant role towards the possibility of sustainable colonization of extraterrestrials. Safety in passenger transportation has in turn given rise to the need of credible, reusable spacecraft. This will create strong transport mechanisms that will make repeated cargo and personnel transfers to the off-world bases and give a basis of logistic network infrastructure.
The effect of tourism in terms of cost saving is huge with the reusable technology. Reducing access into low earth orbit to dramatically reduce costs is a requirement to achieve economically viable colonies. This affordability frees funds to be invested in making permanent extraterrestrial habitats and life-sustaining infrastructure.
Tourism promotes resource recycling and resource use. The safety of the passengers requires effective air, water, and waste recycling in the vehicles. Such systems would be essential in survival of colonies that have low resupply potential and are not dependent on external resources, since the colony could be far away.
Experience in the functioning of tourist space stations gives substantial practical experience. The practical experience in preserving such complicated environments as well as crew rotations can be directly applied to the planning and conducting of long-lasting extraterrestrial settlements.
Lastly, space tourism brings in enormous personal funds and market mechanisms. This investment boosts necessary advancement of technology. More importantly, it forms an initial economic opportunity that pays to expand and build infrastructure to support colonies that are self-sustaining.
Conclusion:
Sustainable colonization will be absolutely incomplete without space tourism developments. They provide cost-efficient transportation, downward pressure of payment, sophisticated life support, work experience and essential personal venture. To produce self-sufficient colonies, special attention should be paid, but the systems of bases that tourism has developed should form the basis.
