Editor's note: This week Melvyn Bragg and his guests discussed the Moon. As always the programme is available to listen to online or to download and keep - PM.
Immediately after the programme Carolin produced a piece of the Moon. It was a sliver of a lunar meteorite which had landed in the Sahara. It was strange to hold something of the Moon. Immediately they went into a discussion about the future of space travel and space exploration. One of the contributors spoke of the Treasury's reluctance to fund it; apparently in space the Treasury is interested only in what we can learn about the weather, or... well, that seems to be about it.
Meanwhile, the Chinese, twenty years ago, set up a plan for space which they are steadily achieving. They have hit every target so far, Paul Murdin said, though not precisely on time. Their next big goal is to colonise the Moon and he's quite sure that they will.
This scares the USA, he says, because it is still interested in global competition, even though it is not feeding its own space programme at the moment. But space programmes can be recreated, as Kennedy did when he created NASA to put men on the Moon.
There is a tendency to compare the Moon with the Antarctic and say that it will belong to everybody and nobody. This was dismissed by those around the table. Paul Murdin didn't even think it would really apply to the Antarctic much longer. He'd been in Australia when there was a row about Australian scientists putting up a statue of a famous Australian explorer in the Antarctic. The committee demanded to know why waste so much money. It was explained that they were staking a claim. The committee demanded to know why the statue wasn't much, much bigger.
The idea of war for and on another planet (starting with the Moon) has ceased to be H G Wells and is coming into view, it seems.
Afterwards I went across the road with Tom Morris, the producer, and we worked out the programmes until Christmas and sketched in a few for January. Then a discussion with a former producer of In Our Time, James Cook, who is working on another project.
And so down Regent Street in the drizzle.
Still very warm in London, but this lovely, refreshing drizzle. I walked along the Mall, slushing my feet through the dead leaves, and was instantly taken back to childhood autumns when this was a big thing to do. Trailing your feet in these piles of leaves. The sound and the sensation came back in a flash. It's curious how tiny moments can electrify you.
The other night I was in the Parks in Oxford. I'd gone back to my old college and I was walking around the Parks in the dusk, enjoying the dusk thickening, the river darkening and still as glass, the paths disappearing between high bushes.
Suddenly, behind me, a voice - it must have been that of a five- or six-year-old girl (I didn't want to look round in case I spoiled it all) - began to sing "Twinkle, twinkle little bat, how I wonder what you're at". And she kept on singing it! Then she laughed and it really was peals of crystal. Her mother (or was it her mother? I didn't want to look round) then joined in. And suddenly I was - on another planet? It felt like that and it's stayed with me already for over a week and I suspect it will linger around, or I want it to, for a long time to come.
And speaking of the Moon, we forgot to make any real reference to poetry. Paul Murdin's favourite Moon lines are from Keats in Endymion:
"What is there in thee, Moon! that thou shouldst move / My heart so potently?"
And found among Shelley's papers was this poetic fragment:
"Art thou pale for weariness / Of climbing heaven and gazing on the earth, / Wandering companionless / Among the stars that have a different birth, / And ever changing, like a joyless eye / That finds no object worth its constancy?"
