Other news sites are reporting an plan to colonize the 4th rock from the sun; and recruiting for one way trip volunteers will begin in a few months.
Would a Jew have to wait for the planet to line up with Jerusalem in order to pray?
April 16, 2013 4:54 pm at 4:54 pm #949851WolfishMusingsParticipantWould a Jew have to wait for the planet to line up with Jerusalem in order to pray?
Of course not. Facing Jerusalem is optimal but in no sense required to the degree that prayer is impossible without it.

April 17, 2013 3:10 am at 3:10 am #949852This name is already takenParticipantwhen do you keep shabbos and yomtov
April 17, 2013 4:24 pm at 4:24 pm #949854Rav TuvParticipantor chalav Yisroel? birkas hachama? And of course there would have to be zionists there so there would be someone for the “real Jews” to hate
April 17, 2013 6:13 pm at 6:13 pm #949855popa_bar_abbaParticipantAnd of course there would have to be zionists there so there would be someone for the “real Jews” to hate
the zionists would have been willing to make their state on mars.
April 17, 2013 10:25 pm at 10:25 pm #949856squeakParticipantI say let the zionists go. They will figure out how to turn the landscape into a flourishing paradise and within the decade, Martians will claim that they were there first. Its the surest way to make contact with ET.
April 28, 2013 4:43 pm at 4:43 pm #949857Charles ShortMemberYeah; when would you keep Shabbos?
I’m guessing you would have to use a reference clock and base it off of earth time.
April 29, 2013 1:18 am at 1:18 am #949858VogueMemberWhat does Zionism have anything to do with this?
April 29, 2013 2:07 am at 2:07 am #949859YW Moderator-42ModeratorWelcome to the CR – where everything has to do with Zionism, Shidduchim, PBA, or Joseph.
April 29, 2013 2:08 am at 2:08 am #949860YW Moderator-42ModeratorI just realized that the best way to colonize a planet is to send Joseph there. That would increase the population exponentially.

April 29, 2013 3:08 pm at 3:08 pm #949862HaLeiViParticipantThe problem is that air conditioning won’t work, since there is no air to cool the coils. Oh, well in that case, temperature won’t dissipate, either. So you can cool the coils with cool water from the winter.
Which Mazalos do they count there, ShaTzaA ChaNKaL? In what order?
As for Birchas Hachama, if you go with the geo-centric model then it doesn’t change, since the sun is said to have come into the correct position. If, however, we go the helio-centric model then the question is do we, as earthlings, still count by the sun’s relationship to Earth or from our perspective?
The thing with Birkas Hachama is than it isn’t an observed phenomenon in the first place.
Shabbos is discussed already by some Poskim, since it was Nogea the Israeli astronaut.
April 29, 2013 6:36 pm at 6:36 pm #949863BaalHaboozeParticipantAnd of course if a jew goes he would have to set up TWO shuls, just so he can use the first one, and NEVER go to THAT one!

Actually, the constellations on Mars would be the exact same as the ones on Earth. The distance between Earth and Mars is not great enough to change the shapes of the constellations.
However, there would be two major differences.
First, the North Star on Mars would not be Polaris, as it is here on Earth*. There is no true North Star on Mars — the celestial North Pole from Mars would pass through a point between Deneb and Sadr.
Secondly, the path of the Zodiac is slightly different than here on Earth.

* Yes, I know Polaris isn’t exactly on the celestial North Pole, but it’s close enough for everyday purposes.
April 29, 2013 8:30 pm at 8:30 pm #949865HaLeiViParticipantI wasn’t referring to the 12 Mazalos of the zodiac. I was talking about the seven heavenly bodies. We would have to switch Mars for Earth.

Ah, I misunderstood. My apologies.
It would be a bit more complicated than simply switching Earth for Mars.
Firstly, of the “planets” of antiquity, the moon was first because it was closest to Earth. An observer on Mars, of course, would not find this to be so. In addition, since the Moon orbits the Earth and not Mars, I’m not even sure how it should be represented, if at all.
In addition, Earth would have to be third and the Sun fourth.
Lastly, Mars has two moons and they are very different from Earth’s moon. Unlike the “planets” of antiquity as seen from Earth, Phobos rises in the west and sets in the east.

April 29, 2013 10:13 pm at 10:13 pm #949867Oh Shreck!ParticipantFirst there’s a problem with the brocha on bread – hamotzie lechem min …?
Then, of course, once we’re up there, a lot of planets can get decommissioned (like Pluto alav hashelem).
April 29, 2013 10:45 pm at 10:45 pm #949868squeakParticipantThere are no tznius problems on Mars. You can’t go outside even slightly exposed, and there are no beaches to be found anywhere.
There are no fancy foods or extravagances.
Your neighbors’ homes will be the same as your own.
There is no shidduch crisis. Two men and two women only. No matter how far apart they are in age, this island is a win.
It’s a kanoi paradise. Submit an application and post here, I’ll vote for you. The only downside I can think of for a guy like Joe is you can only have one wife (at least you can only take one along with you).
April 29, 2013 11:01 pm at 11:01 pm #949869☕ DaasYochid ☕ParticipantUnless you eat Mars bars (you’ll have to switch to Earth bars).
April 30, 2013 12:03 am at 12:03 am #949870HaLeiViParticipantOnce we settle multiple planets, we will have to deal with Universal Warming/Cooling being pushed by the United Planets.
April 30, 2013 1:38 am at 1:38 am #949871letschmoozeMemberIt would be the same as the moon.
April 30, 2013 6:19 am at 6:19 am #949872Oh Shreck!ParticipantSend regards (second pair of guards) to Dr. Doomshtein.
April 30, 2013 2:48 pm at 2:48 pm #949873ZachKessinMemberSome notes on mars:
The problem is that air conditioning won’t work, since there is no air to cool the coils.
Actually there is air on Mars, not very much of it, but some. You would not be able to breath it (wrong chemistry and not nearly enough pressure)
As for Luna (Earth’s moon) it would actually be visible from Mars, Earth would appear as a double planet. However Mars’s moons are very small and have very fast orbital periods.
A “day” on Mars is called a “Sol” and is about 25 hours.
How to construct a Mikva or Sukkah on Mars is left as an exercise for those more creative than I.
April 30, 2013 3:55 pm at 3:55 pm #949874HaLeiViParticipantWhen talking on the phone to an Earthling, what would be the delay?
Zach, welcome back and thanks for stopping by. Did you come here by chance or did someone tell you about this topic?
April 30, 2013 7:21 pm at 7:21 pm #949875Oh Shreck!ParticipantJust wondering, if someone reaches and touches moon, is that a bad omen…
May 1, 2013 4:23 am at 4:23 am #949876ZachKessinMemberHere by chance.
As for the delay it will range between about 4 minutes when Mars is at Opposition to about 24 minutes. And there will be about a month a year when mars is behind the Sun (at Conjunction) where you would not have any communications.
Of course from Mars it would be that Earth is at Inferior Conjunction (Closest) and Superior Conjunction when it is behind the Sun.
(Opposition is when an object is directly oposite the sun and therefore the closest to the Earth)
Actually Saturn is at Opposition this right around now, and the rings are wide open so if you know someone with a Telescope go take a look.
May 1, 2013 6:53 am at 6:53 am #949877HaLeiViParticipantThanks. Interesting. What angle is the rotation of Mars? I mentioned seasons, but I’m not sure it actually has them. Also, you mentioned that it has some air. Does that air actually conduct heat?
May 1, 2013 7:05 am at 7:05 am #949878ZachKessinMemberThe air will conduct heat, but not very well, it is very thin, very dry and very cold.
Mars rotates at an angle of about 25Degrees, Earth is about 23Degrees, the closest bright star to the pole would be Deneb, which is in Cygnus, but I don’t think it is very close to the pole.
Mars does have seasons, but they would be about twice as long as ours as a year on Mars is about 687 Earth Days. You can actually see the polar ice on mars advancing and retreating with the seasons from Earth with a decent telescope. I would expect that you could in fact keep track of that with about $600 worth of telescope and a sketch pad
