The flight, which originated from New Mexico in the United States and was live-streamed on the Virgin Galactic YouTube page, was completed this morning, July 11, 2021, onboard the rocket plane known as Unity 22, which has been in the making for 17 years.
Branson, who owns two private islands in the Virgin Islands, was accompanied on the mission by Unity's two pilots, Dave Mackay and Michael Masucci, and three Galactic employees - Beth Moses, Colin Bennett and Sirisha Bandla.
The entrepreneur has billed the flight as a test of the space tourism experience he expects to begin selling to customers from next year.
According to the BBC, some 600 individuals have already paid deposits for tickets that will cost them up to $250,000 (£180,000).
Space tourism, according to the BBC, is a sector being rekindled after a decade's hiatus and is about to get very competitive.
It said throughout the 2000s, seven wealthy individuals paid to visit the International Space Station (ISS). But this adventurism, organised under the patronage of the Russian space agency, ceased in 2009.
Now, new initiatives abound. As well as Sir Richard's approach, there are projects coming from Amazon.com founder Jeff Bezos and the California tech entrepreneur Elon Musk.
The Russians, too, are reprising their commercial flights to the ISS, and there are even those who want to launch private space stations for people to visit. Among these is Axiom, a company started by a former Nasa ISS programme manager, the BBC stated.
