An actor has a contract to go to the ISS on SpaceX Dragon to shoot a movie. Tom Cruise is reportedly going to ride on Crew Dragon to the space station in the near future (Verge article). This was announced almost a month before the launch. This is how Earth-shattering this launch is. It's already sparking space tourism.
A billionaire wants to go to space and take artists around the moon. He has a contract with SpaceX. The Dear Moon project by entrepreneur Yusaku Maezawa hired SpaceX to take him and artists on a journey around the moon on Starship. It's the most ambitious space tourism feat yet. The Crew Dragon launch validates SpaceX's ability to launch humans into space and thus to launch them on the yet to be developed Starship as well.
I heard on the webcast of the launch that SpaceX plans on sending making available twice a year on Crew Dragon a year to the ISS. This article from the Verge states that SpaceX made an agreement with Space Adventures to have four private citizens in the next year or so.
Now, the future can open up. Commercial Space Stations project entrepreneurs can make real plans because they have a way to get people to their stations. Axiom Space, Bigelow Aerospace, and the Gateway Foundation have been surely watching eagerly the Crew Dragon launch.
Low Earth orbit, the Moon, Mars, the Asteroid Belt, and deep space are all potential destinations for commercial human missions and colonies. The successful launch of Crew Dragon is amazing and is also the key to an open and profitable space future. Ad Astra.
