Mars methane mysteriously missing

Saw what they did to Virginia, I think the Zags are the real deal this year, they may run the table.

[UnbelievingScumOnTheOtherSide]

The Martians are now trapping the methane due to Martian Warming.

Partner, great line and comeback.>

You read the book?

[[Mars methane mysteriously missing]]

No mystery- Eric Swallwell has it all

[jmacusa]

Guilty conscience, huh? C'mon, come clean and it'll go easy on ya. We know you swiped it!

[Don W]

At least NOMAD was (relatively) easily contained, unlike V-Ger...

Mars hardly has an atmosphere IIRC. Once again, IIRC, this is a function of Mars having next to no magnetic field to shield itself from incessant buffeting from the solar wind.

[jonrick46]

Because Mars does not have a magnetic core, it cannot produce a magnetosphere which shields the planet from the charged particle of the solar wind. It is this solar wind that strips the planet of whatever atmosphere it may produce. Any plans for terraforming Mars are pipe dreams. The solar wind will strip away any atmosphere produced by terraforming—including methane—as quickly as it is produced.

[jmacusa]

You're right. In order to maintain an atmosphere a planet has to have a molten core. This produces a magnetosphere which hold the planets atmosphere in place.

However as the molten core cools down the magnetic field begins to weaken and the atmosphere begins to dissipate.

This is quite likely what has happened to Mars in it's distant past.

I don't think so much a molten core as an Iron core.

Earth's iron core spinning and passing through the magnetic field of the sun generates Earth's own magnetic field.

Mars could be too far away, too small of an iron core (if at all) or having the shit knocked out of it by another heavenly body, creating two moons, and stripping it of all atmosphere.

[jmacusa]

But what produces the iron core? How is iron produced? Heat, wouldn't you say? This is the science I learned.

[going hot]

No, not the heat, not hot enough to "make " Iron.

The heat can in fact keep it molten. (pressure)

Perhaps while coalescing, or even after, the heavier stuff migrating to the middle over eons, Not sure if 100% iron, but definitely more dense elements, in proper percentage.

I don't know why so much iron, or how it got introduced into the system, not within my AO.

Regardless, passing an iron core through a magnetic field, while spinning, will produce electromagnetic fields.
