Real science: Large quantities of water ice on moon

This post is based on a front page story in Bombay "Late City" edition of The Indian Express newspaper today, quoting multiple ISRO & NASA sources.

"New analysis of scientific data from" a NASA instrument called "Mini-SAR" "that flew aboard India's Chandrayaan-1 spacecraft" "found more than 40 small craters (2-15 km in diameter) with sub-surface water ice located at their base. The interior of these craters is in permanent sun shadow".

These craters are all located "in the lunar north pole". "there could be more than 600 million metric tons of water ice in the craters."

While previous investigations by ISRO & NASA have detected water on moon, "this is the first time that evidence has emerged of the presence of large quantities of lunar water."
