Journey Into Space is a BBC Radio science fiction programme, written by BBC producer Charles Chilton. It was the last radio programme in the UK to attract a bigger evening audience than television. Originally, four series were produced (the fourth being a remake of the first), which went on to be translated into 17 languages (including Hindustani, Turkish and Dutch) and broadcast worldwide (including the United States, New Zealand, Australia and the Netherlands). Chilton went on to write three best-selling novels and several comic strip stories, based upon the radio series. The first series was created in 1953, soon after Riders of the Range (a popular Western, also written by Chilton) ended its six seasons on the BBC Light Programme. Michael Standing, then Head of the BBC Variety Department, asked Chilton if he could write a sci-fi programme, and Journey to the Moon (later known as Operation Luna) was the result. Each half-hour episode would usually end with a dramatic cliffhanger, to increase the audience's incentive to tune in to the next episode.
