Question concerning the Miller-Urey experiment

Post by Remedy » Sun Mar 25, 2007 6:05 am

Has the Miller-Urey experiment ever been reproduced with respect to early Martian atmosphere? Just a question that dawned on me, it might be a worthwhile undertaking. We have a dating for the Martian rock, so if we could get a good estimate of those conditions we could shed light on possible Martian genesis theories.

I hav never heard of such an experiment, but it seems to be a good idea.

There shouldn't be that much difference in starting conditions. And we don't really know what the important variations would be.

Well for one, wouldn't mars be colder since its further away? Plus there seems to be a lot more iron there, and we don't really know whether mars had oceans.

It's unclear how much warmer or colder it would have been - heat at that time would have been from volcanism, sunlight (which would have been different then than now - I don't remember for sure, but I think the Sun was weaker then), and greenhouse gases, and how much of each was present.

Earth had a lot of iron once - much of the free iron precipitated from the oceans when photosynthesis really got cranked up.

As far as I can remember, according to the newspapers, they have said that Mars did have water-they proved it, but yup, nothing was spoken about the oceans...
