SpaceX just launched humans to space for the first time
Elon Musk’s aerospace company, SpaceX, just successfully launched its first two people into orbit, ushering in a new age of human spaceflight in the United States. SpaceX is now the first company to send passengers to orbit on a privately made vehicle, and the flight marked the first time astronauts have launched into orbit from American soil in nearly a decade.

SpaceX Crew Dragon - Ushering in a New Era of Human Spaceflight

The flight marked the first time astronauts have launched into orbit from American soil in nearly a decade, and SpaceX is now the first company to send passengers to orbit on a privately made vehicle.
The two astronauts — veteran NASA fliers Bob Behnken and Doug Hurley — rode into space inside SpaceX’s new automated spacecraft called the Crew Dragon, a capsule designed to take people to and from the International Space Station. Strapped inside the sleek, gumdrop-shaped capsule, the duo lifted off on top of SpaceX’s Falcon 9 rocket from NASA’s Kennedy Space Center in Florida at 3:22PM ET on May 30th, 2020.

One thing is for sure... The prospect of space travel will be very different after the launch of Inspiration4.
We can in fact say with reasonable certainty that the date of departure, which at the moment seems confirmed for next September 15, will be the watershed between two historical eras: the one started with Gagarin when orbital space was mostly a realm reserved exclusively for nations and to their selected astronauts... and the one after Inspiration4, when space travel will be definitely within the reach of private companies and ordinary citizens.
It is difficult to say what this transition will mean: whether space travel and its benefits will be democratized throughout society or will be exploited exclusively by corporations and the super-rich. For now, the answer could be a bit of both.
