Arlin Crotts, a professor in the Department of Astronomy of Columbia University in New York City found that the Soviets found evidence of water in the 1970s, in particular the Luna-24 sample-return mission. During this mission the Soviets drilled 2 meters into the lunar surface and extracted 300 grams of rock then returned to Earth. This was an impressive feat for its time. Analysis showed the rock was made up of 0.1 percent water. This result was published in 1978 to the Russian journal Geokhimiia. There was an English version but wasn't widely read in the West."
