Mat Irvine has had a long association with spacecraft modelling, both as an amateur hobbyist and professionally. He was a special effects designer at the BBC for almost 25 years, not only working on SF series such as Doctor Who and Blake’s 7, but also many factual science programmes, from Horizon to Stargazing Live. He also regularly appeared on children’s programmes explaining about the latest space missions. He has also worked closely with many of the model companies around the world, advising on their ‘space model’ output. He has written a number of books and articles on space and modelling and is a Fellow of the British Interplanetary Society.
