Israel’s first astronaut is about to fly on Space Shuttle Columbia. This brings to mind all kinds of intriguing questions. Like, have the Rabbis ruled on when you should observe the sabbath if you’re in a non-geostationary orbit? Do you wear a yarmulke inside a space helmet? Can you operate a space suit on the sabbath or do you have to hold your breath?
Presumably the first Muslim in low orbit will need some kind of motorized zero-G prayer harness with automatic Mecca-seeking action.
