Sustainable Space Tourism
摘要
Sustainable space tourism confronts the same economic and environmental issues. In the first year of space tourism in 2021, Virgin Galactic, Blue Origin, and SpaceX completed five space travels for 21 people that gained much economic and brand value. Taking SpaceX as an example, the gross profit rate is 266% for 55 million US dollars per ticket and four passengers per flight. The net profit is still considerable, even after deducting fixed costs and other related expenses.
