What are the implications, if any, for Earth’s various religions, of colonizing Mars?

Answer 1

What an amazing question! For Jews, it would certainly complicate in which direction we would pray and where the Aron HaKodesh would face! Also, holy day start and end times would be complicated because we wouldn't be on a 24/7 timeline, per se. So, Mars dates and times would have to be recalculated based on start/finish times in Jerusalem, as well as sunrise & sunsets.
