Space tourisim is a thing many space / flight companies want to accoumplish. The idea is supposing taking civilians in space with a rocket, for a very big ammount of money.
Some of the space agencies are Space-X, Blue Origin and Boeing. Space-X has in plan taking in the next years two humans on a trip around the moon using a rocket, that is currently in development.
Blue Origin wants to send a tourist crew to the ISS and back and Blue Origin has also in plan taking tourists in space by the end of 2018.
Space tourism is a game changing idea for all the existing or the furure space companies. It requires a lot of time, money and it is also very dangerous. Like the actual astronauts, the tourists will be prepared for the space travel, and if all goes good, we might be a step closer to colonizing Mars!
