nothing. in the history of astronautics there have not yet been religious Jews. and if there are, there will undoubtedly be such a way that everyone will be surprised: in the interpretation of the prohibitions of the Jewish religious casuistry there was no, no, and probably will not be equal.
Strongly believing Jews (not ready to abandon Shabbat observance during the expedition into space), as far as I know, have not yet been at the space station, and even among the astronauts in general they, apparently, were not observed. So while such a question in practice, fortunately, is not worth it and the answer to it is "in no way".
