For me at least, I hope man goes back to the moon in my lifetime.

Dad has always talked about his memories of 1969 (he would have been a teenager at the time) and the excitement of it.

I feel like going back after so long will feel almost as momentous for some of my generation. Although possibly not the the majority, which is a little sad.



I was 11 then. I have a feeling the actual landing was early morning in the UK, not sure I actually saw that.

I'm afraid my dominant memory is the bleep they had between the voice from the moon and the reply from Houston. A fraction of a second long, and a bit higher than E above middle C. I can still hear that now, with the sort of echo at the end from the satellite relay I suppose.

Dad (born 1930s, RAF technician and then radio repairs) was really excited by it all and loved the technology. Grandad (born 1890s, trained as blacksmith, operated a static steam engine, the kind that powers a mill through drive belts) found it sort of funny. Mum liked it when they got out of the capsules on the aircraft carrier.


Those beeps are known as Quindar tones, and were used to mute and unmute the radio transmissions.

"Because replacement parts are no longer available, an "out-of-band signaling" system was installed in 1998 for the transmitters located in the U.S. This system uses a continuous tone that is below the normal audio frequency range. When the tone is present, the transmitters are keyed. When the tone is not present, the transmitters are unkeyed. It worked fine, but the Astronaut Office complained about the lack of tones which everyone had become accustomed to as an alert that a transmission was about to start. So, the Quindar tone generator, which was still installed in case it was necessary to key the transmitters at an overseas site, was re-enabled. "

Wonderful link, thanks. The quote above almost rivals Primo Levi's story about the paint recipe in The Periodic Table.


Emotionally, it would be great to see a return to manned space exploration, but the intellectual side of me has to ask 1) why return to the moon? and 2) how practical is it to send humans when robots can achieve 80% of the objectives at 20% of the cost, and so much of what is worth visiting is out of reach until we figure out how to dramatically increase the speed of space travel?

Note that the 80% and 20% are sheer rhetorical fabrications.


There aren't any legitimate scientific objectives (meaning we're excluding things like "studying sex at 1/6 G") people can accomplish on the moon that robots can't. And manned spaceflight is about a x20 multiplier, not x5.

So it should really be "100% of the objectives for 5% of the cost". Which, in a nutshell, is why we stopped sending people to the moon.
