Giant steps are what you take, walking on the Moon...

This afternoon at the Edinburgh Film Festival I caught the UK premiere of the documentary by David Sington, In the Shadow of the Moon, detailing the glories (and the tragedies) of one of the biggest undertakings humans ever launched themselves on, the Apollo programme. As soon as I saw this in the EIFF programme this year I knew I was going to see it. I was born at the height of the Space Race; Mike Collins, Buzz Aldrin and Neil Armstrong's astonishing, history-making flight to the Moon on Apollo 11 was still a year and a half away. I grew up with an astronaut space suit costume to play in while Gagarin and Armstrong were on posters as my boyhood heroes (they still are, some things you never grow out of); the idea of space exploration has lived inside me my entire life and as I approach the big four-oh birthday on the last day of this year I get a little sad that those promises of holidays in space we were told the future would hold have never materialised and it looks less and less like that boyhood dream will ever come true.

But still it weaves a magical spell on me; as the footage of those enormous Saturn Vs ascending the heavens on a column of fire flickered across the screen I could feel the old excitement rising - the boy in me is never far from the surface and images and ideas like this always bring it out. Much of the footage has never been seen before and is literally out of this world. The story of our first tentative steps out of the cradle of the Earth to our nearest neighbour is told in their own words by many of the NASA astronauts who made those epic journeys, voyages of discovery that stand in a long line of human endeavours such as the explorations of James Cook, Magellan or those unknown Polynesian sailors who crossed vast oceans on small boats made of reeds.

One of those men featured was David Scott, an Apollo commander - a man I actually met a few years back when his publicist came in to my old bookstore to say he was across the road in the Balmoral Hotel doing interviews with the Scottish press and would we like him to come across and sign some copies of the book he had co-authored with his friend the Soviet cosmonaut Alexei Leonov (the first man to walk in space; his friend Arthur C Clarke would name a spaceship in his honour in the sequel to 2001). An ordinary day at work and then suddenly there I am chatting to a former astronaut and shaking hands with a man who had walked on the Moon; a man who got to live that boyhood dream of mine. Naturally I got one of those signed copies for myself; I've many signed books in my collection but only one signed by an author who has traveled far enough into space to look back and see the entirety of our world hanging in the void. We've all seen the pictures, but it wasn't until the crew of Apollo 8 voyaged around the dark side of the Moon that humans actually saw the entire Earth from space. They took the famous 'Earthrise' photograph, our world rising in the dark above the surface of the Moon, the furthest humans have yet been from our world.

Only a tiny handful of humans have ever seen that sight with their own eyes to this day, all now old men - to look at them in this film you could easily mistake them for someone's favourite uncle of grandfather. But in their prime these men dared death, road on a column of scientific dragon's fire further than anyone in the entire history of the world and in the process changed the way we see our little, beautiful world. It's so sad we've pulled back from those days; I'm not stupid, I'm well aware of my history and understand much of the colossal cost of the space programme was only met because of politics of the Cold War. And yet I can't help but feel we let ourselves become that much smaller as a species when we stopped pushing at the final frontier. Yes, I know we can spend the money on problems right here on Earth, but if we weren't so busy squabbling among ourselves we wouldn't need to waste so much on creating weapons - then we could spend that money on feeding and taking care of people here on Earth and have enough to explore, to go where no-one has gone before.

I still want to go.
