Space seems to be all anyone is interested in nowadays - the world's billionaires are fighting about who builds a rocket and gets there first and we are starting to see images of planets at the edge of our solar system that were just fuzzy blobs decades ago.

Jeff Bezos completed his space fly-by on his Blue Origin NS-16 rocket yesterday and last week, Richard Branson took his suborbital trip on a Virgin Galactic's spaceplane, beating Bezos to the title of "the first billionaire in space" by just 9 days.

Well, Ashton Kutcher has given up his chance to do the moonwalk in the stars because he revealed in an interview with Cheddar News that he's sold his space travel ticket. He had bought the ticket way back in 2012 for one of Virgin Galactic's space travel flights.

Kutcher talked about how it was his wife Mila Kunis who had encouraged the decision, stating: "When I got married and had kids, my wife basically encouraged [me] that it was not a smart family decision to be heading into space when we have young children."

"I was supposed to be on the next flight," he revealed. "I will not be on the next flight, but at some point, I'm going to space."

Branson is slowly bringing the idea of space tourism to the people if you can afford it. Trips aboard the Virgin Galactic's VSS Unity will cost passengers $250,000 apiece. A seat on Jeff Bezos' New Shepard rocket was auctioned off for $28 million in June.

Business Insider reported that 4 passengers paid $55 million for a place on SpaceX private mission with Axiom Space is scheduled to fly to the International Space Station in early 2022.

Around 600 customers across fifty-eight countries have forked out the money needed for a seat on the Virgin Galactic's Unity spacecraft which includes the flight, training, and a spacesuit for the trip. While the trip won't pass the Kármán line, an imaginary boundary between the atmosphere and space, passengers on Unity will reach the height (sixty miles above Earth) before experiencing several minutes of weightlessness and returning to earth.

As Branson floated around in microgravity on July 11th during his Virgin Galactic Unity debut, he taped a message using cameras aboard the space plane: "To all you kids out there — I was once a child with a dream, looking up to the stars. Now I'm an adult in a spaceship...If we can do this, just imagine what you can do," he said.

Well, it seems as if Kutcher has made a sensible decision as a dedicated father... and let's face it, as a multi-millionaire, he'll definitely make it into space onboard one of Branson's flights one day!
