Is that the practical halakhic answer the Rabbi would give to a Jewish astronaut on the International Space Station?

That’s the answer I gave to someone asking sloppy questions on our site here on solid ground.

Benjamin,
one must consider whether recycled urine from a gentile, a resident alien in Israel, or a Canaanite slave is different.
In my humble opinion, drinking recycled urine of a gentile involves a prohibition of seclusion with the gentile. Therefore, a blessing over that urine would be a commandment that comes through a transgression. (And one must discuss whether recycled urine of a resident alien falls under this, since the Tannaim disagreed whether his status in these matters differs from that of an ordinary gentile. And perhaps even regarding the urine of an ordinary gentile nowadays it is permitted to recite a blessing, for Meiri already taught us about a change in Jewish law regarding civilized gentiles.)

It seems Benjamin’s question was aimed at someone to whom the urine has gone to his head, and to that the Rabbi answered practically that he should recite the blessing “Who makes creatures different.”
The question is whether it is enough to see in the writing itself the change in creation of someone whose urine has gone to his head, or whether one must actually see the questioner in person. It would seem that in cases of doubt about blessings we are lenient, so as for Mr. Benjamin, until we see him we should recite only “Who creates many living beings and their deficiencies.”

At first glance, if the recycled urine turns into water, one should recite “Shehakol” only if he drinks it to quench his thirst; but if it has a good taste, one may recite the blessing even without feeling thirsty.

With the blessing, “NASA and we shall hear,” prayer leader

Prayer leader,
It seems our acquaintance Mr. Guyeerolein has already reached outer space, and in space it is doubtful whether there is any sense of taste, so your answer does not satisfy him.
With the blessing, “and created in him many openings… for if one of them were to be opened or one of them blocked…”

But this actually is an interesting question. That is, there are people who drink the first urine of the morning as a remedy (I’m not getting into the argument whether it really helps), and from here perhaps the question is whether one must recite a blessing over something medicinal. And does one derive enjoyment of the palate from it? Is it a violation of “do not make yourselves detestable,” such that even if the taste is good and it is for medicinal purposes, one still would not recite a blessing?
