The Duke of Cambridge has criticized space tourism and the space race, saying that the greatest minds in the world should instead focus on fixing the Earth.
Prince Williams' comments in an interview on Newscast, BBC Sounds, will air the day after William Shatner became the oldest person to orbit.
The actor, who is 90 years old, was best known for his role in Star Trek's Captain James T Kirk. He took off Wednesday from Texas in a Blue Origin rocket, which was built by Jeff Bezos, the founder of Amazon.
Interview with the prince about climate change was conducted ahead of his inaugural Earthshot Prize awards. He stated: We need the best brains and minds in the world to fix this planet and not to search for the next place to live and go.

He warned Cop26 attendees against clever talk, clever words, but not enough action at the Cop26 summit in Glasgow, which will take place at the end the month.
Cop must communicate clearly and honestly, he stated. It is impossible to have clever talk, clever words and not enough action.
William voiced his concern about climate anxiety among young people and stated that it would be a disaster for his oldest son, Prince George to have to discuss the same topic in 30 years, when it would be too late.
Climate anxiety is on the rise. The future of young people is being threatened all the time. He said that it is very alarming and can cause anxiety.
He also said that his father, Prince of Wales, who is well-known for his commitment to green issues, was a very rough ride when he first began talking about climate change.
William was interviewed by Adam Fleming for the Newscast. He said that his grandfather, the Duke of Edinburgh, had initiated the royal interest in environmental matters.
Charles was his favorite character. My grandfather was an early WWF volunteer. He helped with the nature work and biodiversity. I believe my fathers progressed and started talking about climate change more.
Yes, it was a rough ride, but he has proven himself to be a leader in his field. These dangers were well beyond his time.
It shouldn't be that a third generation is coming along to increase the pace. It would be a disaster for me if George was sitting here talking to Adam or your successor in 30 years. We will all be too old by then.
He said that his perspective had changed since having children.
We are robbing our children's future by what we do now if we don't take care. That is unfair, I believe.
William spoke out about his Earthshot prize and said that it was about creating action.
