Chris Martin wants to go into space - but doesn't think he can afford it

He said: "I don't think I can afford it.

"I would at some point, if there was a reason or we were going exploring or something.

"I don't know about going up to come back again."

Despite the criticism the billionaires have faced for their space tourism programmes - including from Prince William, who urged entrepreneurs to use their wealth to focus on saving the planet - the 'Higher Power' singer believes they will have many positives.

He is quoted by the Daily Star newspaper as saying: It's like an amazing Disneyland ride.

"I respect those people because there might be really hopeful things for making life on Earth better for everyone and someone has to do it."

The 'Sky Full of Stars' hitmaker is "open to believing in" aliens.

He said: "In terms of other life forms in the universe, we are open to believing anything. It's so huge, the possibilities are endless."

Chris previously dec lared he'd love to perform on the moon , although no-one would be able to hear it because space is a vacuum with no sound.

He said: “Not many people have done it, that’s true. But isn’t there an issue that if you play on the moon no one can actually hear? I am ¬confused about the atmosphere.

“We would try anything twice. I don’t mind any ridicule as I just speak what feels true to me. That is what we all have to do.”
