How easy it is to forget the cold war. In 2012, we cannot look back at scientists of 1976 and say "you should have read and believed this obscure Russian science journal and the argument would have been put to permanent rest". 1976 was a different time in Russian-American relations especially when it came to space.
The article ends by saying our belief of water on the moon has improved from "one part per billion" in 2006, to "one part per million" today, like it's a huge revolutionary improvement. I know it's 1000x, but its still just one part per million. So it takes a million gallons of moon rocks to extract one gallon of water?
Which makes me wonder what the water ppm of Earth is.
I think that mission "only" came to be, because both sides had to have a backup/rescue kit. The hot-spare became useless when both capsule-based (Soyuz/Skylab-Apollo) programmes came to an end with their last flight. By combining, they both got another "free" flight: it was too good to pass up the billion dollars found free with the deal.
I once had the privilege of driving a bunch of astronauts and cosmonauts around town. They all expressed the attitude of "regardless of our political differences, we've all experienced the same extraordinary thing, and that makes us brothers." Though the space programs in the 60s were very competitive in a political sense, those who were actually dealing with the realities of space (including the engineers on the ground) had tremendous respect for each other. There was a huge amount of cooperation between the two sides.
There's not much to it. It was a few years back at one of the annual Space Congress events (http://www.spacecongress.org/ ). I was working for an aerospace museum and was tasked with picking up some of our VIPs at the airport and taking them to their hotel and then to our museum. Most of them had met at previous events, and treated each other like old friends. Two of them (IIRC, Dirk Frimout and Yury Usachev) got into an extended discussion about places they'd visited in my hometown. I don't quite know how to communicate how normal it all seemed -- as if they were family members talking about childhood, rather than members of opposite sides of what had been a bitter rivalry.
If you ever have a chance to talk to an astronaut or cosmonaut, don't pass it up. They are all incredibly brilliant people.

That makes no sense. Actually BECAUSE of the cold war Americans should have studies Russian scientific results more at the time, even to the point of spying on them, not just reading published journals --after all you don't want the "enemy" to have an advantage over you.
Thomas Schelling argues in The Strategy of Conflict that in a cold war situation the belligerents might actually encourage spying to make sure the other side has accurate information. (The accurate information being necessary for effective threats of mutually assured destruction.)

If we believe the Russian data then they found one part per thousand. By mass. So a gallon of water would only require you to process three hundred gallons of rock. And the "processing" isn't that difficult: heat it up and collect the vapor.
Besides, even if it is parts per million, that ain't bad. According to http://en.wikipedia.org/wiki/Open-pit_mining gold can be economically mined at a couple of ppm, while copper and nickel are mined at parts per thousand.
