Massive Flow on Mars

Cool image time! The image on the right, cropped to post here, comes from a Mars Reconnaissance Orbiter image that shows a massive relatively recent and dark slope streak that emanates out from a single point on the surface.

New pictures released last week from the Mars Reconnaissance Orbiter. The MRO release focuses on the fingerlike breakup of the flow as it descends into sand-dune filled plain.

Not impressed - I’m going back to watching Dr. Pimple Popper ...

“Streaks form on slopes when dust cascades downhill. The dark streak is an area of less dust compared to the brighter and reddish surroundings. What triggers these avalanches is not known, but might be related to sudden warming of the surface.”

Global warming on Mars! It’s Trump’s fault!

Impacts from space produce the heat that makes water run on Mars, my usual text, blah blah blah. Also pinging the old APoD members. Thanks Voption.

I’ve never been to Mars but I imagine it’s quite lovely.

[VanDeKoik]

Heh.

I was going to go there myself.

[carmen2017]

Its what happens when all the martians Flush their crappers at the sametime.

[Gamecock]

Hehe, took me a second.

[freedomlover]

Well I’ve never been to Mars

but I’ve been to Oklahoma

[NonValueAdded]

I kinda like the Beatles

[Duchess47]

Now that is really interesting.

[Monkey Face]

WHOA!!! :o])

Thanks!

Gravity works on Mars!

hydrocarbons?

I’m not sayin’ it’s tailing from alien dilithium mines but it looks like tailings from alien dilithium mines.

OIL ON MARS

'... it is not likely that either of the rovers will pick up any evidence of oil on Mars, as they are currently located in places without seeps to the surface. Next time a sonde is sent to Mars, it could be sent either to one of the known mud volcanoes, or to places like Hebes Mensa and Acidalia Mensa. Here it should be able to find fluids (most likely brines + a little oil, or light hydrocarbons, including methane) that originate from the interior of Mars.'

'...Here is a close-up of the Oil Spill inside Hebes Chasma, at the eastern limb of Hebes Mensa. The oil has issued out of the collapsed wall of the salt dome at elevation +443 m. It has run down the slope inside Hebes Chasma and pooled on the plain below, at an elevation of -1457 m. The top of the exposed salt dome is at 2807 m, so these dimensions are great. Although the size of the oil pool is large, it would probably not be called "commercial" if it was found on Earth. In Azerbaijan and also in the Gulf of Mexico, there are natural oil spills (called 'seeps'), that are equivalent the one on Mars.'

The Origin of Methane (and Oil) in the Crust of the Earth
by Thomas Gold
U.S.G.S. Professional Paper 1570
The Future of Energy Gases
1993

Hydrocarbons in our planetary system are certainly very abundant, and in all the extraterrestrial examples mentioned almost certainly not related to biology. Also hydrocarbons are prominent among the gases identified in the molecular clouds of the galaxy, and it is from such clouds that the solar system formed initially. The presence and great abundance of hydrocarbons is universal, and no special mechanism for their generation on the Earth needs to be invoked, unless one knew with certainty that they could not have survived the formation process here, although they did so on many of the other planetary bodies. No evidence of hydrocarbons has yet been seen on Mars, Moon, Venus and Mercury... In earlier times there was the belief that the Earth had formed as a hot, molten body. In that case no hydrocarbons or hydrogen would have survived against oxidation, nor would any of these substances have been maintained in the interior after solidification. With that belief, there seemed no other possibility of accounting for the hydrocarbons embedded in the crust than by the outgassing of carbon in the form of CO2, produced by materials that could have survived in a hot Earth, and subsequent photosynthesis by plants that converted this CO2 into unoxidized carbon compounds. This consideration is irrelevant now that we know that a cold formation process assembled the Earth and that hydrocarbons could have been maintained, and could be here for the same reasons as they are on the other planetary bodies.

thanks...I must have read that before and seeing the recent image, jogged my memory.

His papers were maintained online by the university where he last was, but after a few years they just erased everything. I’d already nabbed them into a file I can sometimes find. ;’)
