Space travel has rapidly developed over the last several decades. Once the domain of governments, space travel is now in the private sector. Currently, more than 625 people have signed up for sub-orbital space flights with Virgin Galactic. However, there still are significant barriers in making space travel a reality for the general public. This paper examines problems of conventional propulsion system. Building upon these analyses, several alternative propulsion sources are discussed as new solutions. Moreover, presentation was performed in front of general public and surveys were conducted to assess the perceived accessibility of space travel. Results indicated that study participants considered space travel to be more feasible when cost, safety, and convenience problems were resolved.
