Speaking to the TODAY programme on Monday ahead of the launch, Bezos said: “I’m incredibly excited. I can’t wait to see what it’s going to be like.”

The world’s richest man added that he expected the experience to change him.

He referenced the “overview effect”, a cognitive shift in awareness reported by multiple astronauts during spaceflight, often while viewing the Earth from outer space.

“People say that they go into space and they come back changed. Astronauts always talk about that,” Bezos said.

“Whether it’s the thin line of the atmosphere or seeing how fragile the planet is – that it’s just one planet. I can’t wait to see what it’s going to do to me.”

The Amazon founder also joked with reporters that he did not eat his “last meal” before taking off.

 “I don’t think we should put it that way. Let’s talk about it in a different way.”
