Statistic from public opinion polls shows that almost 50 million people would want to visit space. As a matter of fact, as many as two million people yearly would take the travel beyond the outer limits of Earth’s gravity. The fascination of the public with space travel means the possible development of a space tourism industry with profits that could amount to $10 billion or more a year. So, it isn’t hard to understand the interest in commercial space travel by private businesses. Over six big companies are working to make commercial space travel a reality. Space tourism refers to human space travel for leisure or entertaining reasons. There are many different kinds of space tourism, which include lunar space tourism, suborbital and orbital tourism. At this point, only the Roscomos did orbital space tourism. Works also keep on towards developing vehicles for suborbital space tourism. This is being performed by aerospace companies such as Virgin Galactic and Blue Origin. What is more, Space X, a renowned aerospace manufacturer, also has a plan to send space tourists, which include Yusaku Maezawa, on a free return trajectory in the region of the moon on the Starship. The fact that space tourism is very expensive; it’s a case of an extremely small part of consumers willing and able to buy this amazing experience. There are many choices waiting for space tourists such as, investigate the option behavior between the kinds of space tourism, atmospheric zero-gravity flight, high altitude plane fighter flight, longer duration orbital trip and short duration suborbital flights, etc. At present, just high altitude plane fighter flights, as well as atmospheric zero-gravity flights, are available commercially to tourists in the sector of space tourism. The present approach to space travel and space tourism, as well as the making of space vehicles to access space, are almost all based on additions to existing rocket launch aircraft and rocket plane development.
