Not only is this the first time a commercial company is sending people into space, it is also the first crewed mission to the International Space Station to be launched from American soil in 9 years since the Space Shuttle was decommissioned.
On the 27th of May SpaceX will make spaceflight history by being the first commercial company to transport humans to the ISS on a Falcon9 rocket in the SpaceX Dragon Crew spacecraft.
This is the beginning of commercial spaceflight and potentially the beginning of space tourism.
