Britain's Prince William has launched an attack on space tourism, urging more attention on problems on Earth.
The comments were to the BBC a day after Star Trek's William Shatner, pictured, became a real space traveler on Blue Origin's second crewed mission.
That replayed its maiden human flight in July, which included its founder, Jeff Bezos of Amazon, and was seen as a breakthrough for space tourism.
William said: "We need some of the world's greatest brains and minds fixed on trying to repair this planet, not trying to find the next place to go and live."
Senior colonels Wang and Ye Guangfu, both aged 41, and the 55-year-old major general Zhai Zhigang will be taken by the Shenzhou-13 spaceship into space tomorrow.
Virgin Galactic, which offers a similar experience of a few minutes' weightlessness, launched its founder, Richard Branson, a few days before Bezos.
William was speaking before the inaugural Earthshot Prize awards on Sunday, his initiative to honor those working on environmental solutions.
