Jeff Bezos has successfully shot himself into space onboard a rocket made by his own Blue Origin private space company.
It is the first time Blue Origin has carried humans to Earth, and Mr Bezos becomes arguably the first ever billionaire to take himself to space.
The Amazon founder – along with his brother Mark, aviation pioneer Wally Funk and 18-year-old Oliver Daemen, whose father bought his ticket – left the Earth onboard the New Shepherd rocket before falling back down to Earth.
Ms Funk is now the oldest person to have travelled to space, and Mr Daeman is the youngest ever person.
In between, they spent 11 minutes travelling up to space and experiencing a brief moment of weightlessness.
Mr Bezos and the company have suggested that the journey could be a major step for space tourism, research and plans to explore the rest of the solar system.
But critics have argued that billionaires would be better off spending their money to solve problems on Earth. Mr Bezos said such critics were “largely right”, during an interview, but suggested that his trip could help solve those problems.
