Flights will depart Spaceport America in Las Cruces, N.M. Before taking to the skies on a 90-minute journey, travelers will undergo "several days" of preparedness activities, Virgin Galactic said. Guests will have access to other activities when astronaut-specific training is occurring.
Spaceflight reservations give the traveler access to the "Future Astronaut" community, where members can access experiences, events, trips and more in advance of their trip to space.
