The Duke of Cambridge has criticised the space race and space tourism, saying the world’s greatest minds need to focus on trying to fix the earth instead. William’s comments, in an interview with BBC Newscast on BBC Sounds, will be aired the day after Star Trek’s William Shatner made history by becoming the oldest person in space. The 90-year-old actor, known for his role as Captain James T Kirk, lifted off from the Texas desert on Wednesday in a rocket built by Amazon founder Jeff Bezos’s space travel company Blue Origin.
