'There are hidden references in most of the pictures. The last space shuttle landing had a wake-up alarm at 6.07, the time of the alarm above. Next to my bed is Yuri Gagarin’s electrocardiogram chart' Photograph: Tim Dodd
'The newspaper says 'Man in space" – this was the front page of the Evening Gazette on 12 April 1961. He's holding a Nasa mug, and there are seven spacesuits in the closet. That is the capacity of a space shuttle, which could fly seven people” Photograph: Tim Dodd

'Everything on that licence plate has a meaning: G04 TLI means 'go for transmitter ignition', which is what Houston would say to Apollo missions when they'd head towards the moon. It also reads 'sea of tranquility', which is where Apollo 11 landed' Photograph: Tim Dodd
'I live in a town of about 40,000 people which has a pretty tight-knit community. Most of the people at this concert knew who I was, so it wasn't a huge shock. This is the only picture I didn't take myself – usually I'll set up a tripod and time it' Photograph: Tim Dodd
