This document discusses the past, present, and future of space tourism. It describes how space tourism started in 2001 with private citizen Dennis Tito paying $20 million for a trip to the International Space Station. Since then, several commercial space companies have emerged seeking to make space tourism available to more people at lower prices. Virgin Galactic aims to offer trips to the lower reaches of space for $200,000, and as the industry develops further, costs could drop to as low as $20,000 per trip within 15 years. The future of space tourism is promising as hotels are planned for space and point-to-point travel across the globe may be possible in only a few hours.
