CHILDREN, it's your chance again to question a real space rocket scientist on LASAR Radio tomorrow (May 1). The community radio station's 'Rocketman' Derek Walker will be live in the studio awaiting your calls and texts. Contact Derek on his 'Cheddleton Chats' Show, between 2pm-4pm, and feel free to question him about his career as a space rocket scientist. Derek will be over the moon if you call him on 01538 528466 or text 07376 194154. He reckons he could be the oldest living original UK space scientist at the age of 80, having gained a post in the prestigious Space Department at RAE, England’s version of NASA, after graduating from Manchester University in 1960.
