What is space tourism?
Space tourism today generally refers to private companies providing short, relatively low-altitude suborbital flights to paying (typically wealthy) consumers. Suborbital is less technically complex and requires less training – involving as little as just 3 days of training. Space tourism flights can be as short as 10-15 minutes, with passengers propelled just above the Kármán Line – 62 miles above sea level and considered the beginning of space – for a few minutes of unbuckled weightlessness. In contrast, private orbital missions for civilians (e.g. SpaceX) are significantly more complex and expensive.
