re: No lunar ice on the poles
I said "It seems to me that there are million of square miles in the lunar polar region in which the sun never shines and Earth can never be seen on the horizon [the top of the earth can't be seen- nevermind that the equator can't be seen]."
Correction: About a hundred thousand of sq miles not millions of sq miles [California has 155,959 sq miles]. But needless to say a lot of land area in the dark.
