I don't do Facebook and have data capped satellite internet so I don't do many videos either. Can anyone provide a quick recap?

They have found organics on Mars but cannot confirm related to biological organisms. They have noticed that the airborne methane levels increase and decrease seasonally. 3 times higher during summer/autumn and lower in winter/spring.


The next mission, the InSight rover, will land in late November. It's primary function will to study the geological history of Mars.

I thought they were going to announce a mission to California to see if there is evidence of intelligent life!

Thanks. How can they have climate variations without humans?

It's that damn Mars Rover we left there that is causing Martian Warming.

Maybe the planet is in the range to see effects of the sun?

Of course there is life elsewhere in the universe. It would be foolish to think otherwise.

I'm betting we know a lot more about this besides some "organics" found on Mars.

Time travel is not impossible, just don't expect to be alive from being that much older. They can do the speed they need, but can not go that fast with weapon systems.

Humans have only been around on Earth a small percentage of the time the planet existed. A few hundred thousand years compared to 4+billion years. Global warming due to humans is only the latest factor impinging on atmospheric conditions.

Paleoclimatology is the study of changes in climate taken on the scale of the entire history of Earth. It uses a variety of proxy methods from the Earth and life sciences to obtain data previously preserved within things such as rocks, sediments, ice sheets, tree rings, corals, shells, and microfossils

The subject matter is not capable of proper study without some comprehension of the science and data available. The early formation of life depends on many things. The atmosphere, organic and non-organic materials, temperature and a host of other factors all come into play.

In a sense early martian Paleoclimatology is covered in the latest Mars Rover info.

Nasa Mars rover finds organic matter in ancient lake bed

Curiosity digs up carbon compounds that could be food for life in sediments that formed 3bn years ago

https://www.theguardian.com/science/...cient-lake-bed

Nasa’s veteran Curiosity rover has found complex organic matter buried and preserved in ancient sediments that formed a vast lake bed on Mars more than 3bn years ago.

The discovery is the most compelling evidence yet that long before the planet became the parched world it is today, Martian lakes were a rich soup of carbon-based compounds that are necessary for life, at least as we know it.

Researchers cannot tell how the organic material formed and so leave open the crucial question: are the compounds remnants of past organisms; the product of chemical reactions with rocks; or were they brought to Mars in comets or other falling debris that slammed into the surface? All look the same in the tests performed.

But whatever the ultimate source of the material, if microbial life did find a foothold on Mars, the presence of organics meant it would not have gone hungry. “We know that on Earth microorganisms eat all sorts of organics. It’s a valuable food source for them,” said Jennifer Eigenbrode, a biogeochemist at Nasa’s Goddard Space Flight Center in Maryland.

We came here from Mars.
We spoiled the Martian atmosphere by man-made pollution and had to seek a new planet to move to.

Earth was close so we harnessed the hot air we generated and used to power huge zeppelins to carry us here.

We used the air to breath as it cooled off.

Nanno Nanno!
