NASA's Curiosity Rover Finds Complex Organic Matter on Mars

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.


“While we don’t know the source of the material, the amazing consistency of the results makes me think we have a slam-dunk signal for organics on Mars,” Eigenbrode added. “It is not telling us that life was there, but it is saying that everything organisms really needed to live in that kind of environment, all of that was there.”

Organic compounds are the precursors of life, and with the growing evidence of substantial amounts of water on mars in the ancient past, that means there almost certainly was life on mars.  It's just a matter of time before they at least find fossilized bacteria.

If life is abundant throughout the universe, enough so that multiple planets in a solar system (at the very least) have had life form and exist upon them, then doesn't that pretty much seal our species' fate in the long term?

Or will we be the unique species, at least in the galaxy, which sets off and successfully navigates the technology required to explore the galaxy without killing ourselves?

The NASA Mars Discovery probe was able to dig a few inches into the old lake bed soil to get these results. The thin Mars atmosphere allows radiation to degrade organic compounds in the soil to a depth of 2 feet.

The next probe to it Mars will be from the European Space Agency. It will be able to drill down to a depth of five or six feet and gather samples for analysis. This likely will provide enough data to answer many questions raised by the Discovery data.

Recently read that a number of red dwarf stars relatively close to our solar system have rocky planets in their "habitable zones". Unlike our sun, which will go super nova in about five billion years, these red dwarfs are likely to be stable for 100 billion years or more. One problem is that these other planets are close enough to their suns that conventional rocket fuels/craft are not powerful enough to escape their sun's gravity iin those habitable zones. We'll have to develop more powerful forms of interstellar propulsion ever to visit these other worlds.

That's bordering on one of the explanations for the Fermi Paradox*. (basically stated, why haven't we met aliens) that it's the nature of intelligent life to destroy itself..



*
The Fermi Paradox seeks to answer the question of where the aliens are. Given that our star and Earth are part of a young planetary system compared to the rest of the universe — and that interstellar travel might be fairly easy to achieve — the theory says that Earth should have been visited by aliens already.

As the story goes, Italian physicist Enrico Fermi, most famous for creating the first nuclear reactor, came up with the theory with a casual lunchtime remark in 1950. The implications, however, have had extraterrestrial researchers scratching their heads in the decades since.

"Fermi realized that any civilization with a modest amount of rocket technology and an immodest amount of imperial incentive could rapidly colonize the entire galaxy," the Search For Extraterrestrial Intelligence (SETI) Institute in Mountain View, California, said on its website. "Within ten million years, every star system could be brought under the wing of empire. Ten million years may sound long, but in fact it's quite short compared with the age of the galaxy, which is roughly ten thousand million years. Colonization of the Milky Way should be a quick exercise."

I imagine it would be even quicker, without the need for transporting life alongside of these exploration vessels. Just a self-replicating vehicle with advanced AI. Land on a planet. Make 10 more of itself with the resources available on the planet, then launch those 10 towards 10 more planets.

I'm obviously not the one who dreamed the above up, and in fact it could be a version of what Fermi himself had said. The AI-ship that landed on the planet could seed life as well, if the planet had none. Or even if it did.

But we don't see that. Or maybe we are that.
