With space tourism in its infancy, the risk perception is high. Earth-based adventure activities have a known risk frequency, amassed by the millions of thrill seekers who have taken part and the small percentage who have, unfortunately, been injured or worse. Those statistics are not yet available for such a new risk so rating is influenced by caution but, as time goes by, rating will start to reflect the actual risk.

Most commonly, travellers think about how to protect their trip investments, followed by potential risks when it comes to unforeseen expenses such as emergency medical treatment, evacuation and transportation back home.
