The mission Commercial Crew Demo-2 of Crew Dragon from SpaceX will begin today as scheduled with humans on board.
It will carry NASA astronauts Doug Hurley and Bob Behnken to the International Space Station. Space X and NASA have said they could make the call as late as around 45 minutes prior to the planned launch time about whether or not to delay. This would be the first time that people have gone into orbit on a private rocket. After this Falcon 9, the rocket which carries it to orbit, will be certified for regular operational use by NASA and will begin offering regular transportation services for astronaut crew to and from the International Space Station.

SpaceX has already begun plans to also offer berths on Crew Dragon to private citizens and potentially commercial scientists and other passengers. Private companies not only jumped into the NASA contracting business, they also started reinventing much of the space business centered around satellites and rockets to launch those satellites. Some of them will do soon even space tourism. NASA's top priority is a rush program to return astronauts to the moon by 2024. Investors and entrepreneurs will be needed. They will be seeking the enormous profits promised by space commerce.
