We didn’t detect any previously unseen organic material on Mars.

We’ve finally detected carbon concentration simmilar to what we’ve expected to see based on mars originated meteorites found on earth and we’ve now have more evidence for a cyclic release of methane on Mars however methane isn’t rare it’s a combination of the most and the 4th most common elements in the universe.



Methane isn't rare, but it also isn't stable. Something must be producing it, somehow. That's the interesting part.


Methane like all other simple and even complex organic and near organic compounds is produced through photochemistry constantly in the solar system.

Titan is full of it, Jupiter has more of it likely than all of the solar system combined, and we’ve already proven that cosmic dust and comets smell like farts.

Mars with its thin atmosphere and lack of magnetic field would be producing organic compounds constantly as high energy cosmic and solar radiation hits the surface.

If anything for Mars it seems that the source of hydrogen might be a bigger mystery but it should have enoguh water in the soil to be ionized and broken down into molecular hydrogen and oxygen allowing organic compounds to form.

The interesting part is the cyclical release during the hottest months of the year it could be biological but it could also and much much much more is just a seasonal pheonomon tied to the temperature.


> cosmic dust and comets smell like farts.

Just imagining a kid at a science fair having made that legitimate discovery but being dismissed by teachers


Methane is odorless [1].

AFAIK the smell in farts is mercaptanes (thiols, organic sulfur compounds).

Yep but Sulfur compounds are not rare, ammonia, sulfuric acid many other sulfides and non sulfuric complex molecules like formaldehyde exist in space in plenty.


But why it is not stable on Mars? Mars is colder than Earth and have no free oxygen. Maybe underground gas leaks in atmosphere and, because atmosphere is much thinner, colder, and lacks O2, it just stays in atmosphere longer and in higher relative concentration.
