Where do we see a hint in the Torah for a person landing on the moon?
R' Chaim Kanievsky provides the answer. The gemara comments on לא בשמים היא, the Torah is not in heaven, that if it were in heaven, you need to ascend to get it. R' Chaim Kanievsky says from this you see that a person can ascend to heaven and land on the moon, located in heaven.
