Viking robots found life on Mars in 1976, scientists say

They were looking for evidence of cellular respiration. Some of the compounds were indicative of life, but other tests lead the team to believe that the signatures could have been from non-organic reactions. They opted for the safe conclusion.

A Slim Whitman album of David Bowie covers would be interesting, too... imagine Slim yodeling Fame

Oh, that was Killer Tomatoes, nevermind.

She sent off for his albums. I love the "Mars Attacks" references to him.

One of these presumably.

there is a little restaurant near here that has a very quirky art collection. paint by numbers, a lobster boy circus banner, and lots of these trash sculptures. mostly animals, fish and a couple great chickens.
fun little joint.

It was a big story for awhile and then kind of just fizzled.

I presume...

... being retired does have its perks...

It's been a while since I followed the story of the rovers though, so I could be wrong.

Claimed it was electrostatic whirlwinds or something.

Of course, they'll claim almost anything is electromagnetic, but in this case it sounded vaguely plausible.

It's what they're good at.

The ones who "opted for a safe conclusion", as someone upthread put it.
They shouldn't have opted for any conclusion, the results were inconclusive at the time.

Scientists in the past did not take the "safe conclusion." I think they would have liked to have been proven wrong, but they correctly countered Levin time and time again with proven experiments that refuted his (or his groups') explanation.

Two things are going to happen.

1) The authors will determine if there was variation during the dust storm. If so this will provide more convincing evidence and at least make countering the argument more difficult.

2) Other scientists will set up experiments to do geologic analysis on the known chemical composition of Martian regolith and do the numerical analysis to see if it matches. In other words, they'll try to reproduce what the authors have claimed.

If, and only if the other scientists agree, then we can safely say that there's a convincing argument that life likely exists on Mars.

how we SPECIAL ONES made in God's image are only found on Earth.

Dang, I wish I'd thought of that.

Many years ago I used to work with Dr Gil Levin who was the principal investigator for the Viking LR release experiment. I mentioned this to him over 10 years ago. It seemed like the logical and only defintive way to verify if there are organisms there. Its not particularly novel but sometimes researchers dont think of the obvious.

of a mushroom cloud

Damn germs. I firmly believe bacteria are everywhere. They are out to get me. I can't make them stop taunting me from their little invisible-to-the-naked-eye bunkers. The bastards.

I used to work for him at Biospherics in Maryland many years ago. He has been totally obsessed with proving his results were real... and rightly so. I reviewed the data back then and it looked legit to me. I am a PhD biologist.

I think he may finally be getting the credit he deserves. He is an egotistical asshole but he is also a scientific genius. I guess those often go hand and hand.

I do hope he's right but I'm not going to jump up and down about it! We'll have to wait to see if any alternate explanations come up.

For what it's worth I think Mars had life and actually does have life going by the methane releases.

"extraordinary claims require extraordinary evidence" -- Carl Sagan

But yes you are correct it did not move around.

....wow, cool....what if some of those Martian (green?) bacteria made their way back to the Earth, nothing would have immunity....

....could you imagine the terminal case of jock-itch caused by Martian kooties?

and We now know that life exists on other planets....
so the next step is
if mankind evolved from microbial organisms as evolution theory says

then more complicated and intellectual life may exist out in space

the possibility turns more into reality

that bacteria climbed aboard a space ship and headed off towards a distant blue dot.

Drug-Resistant Bacteria Found in 4-Million-Year-Old Cave
http://news.nationalgeographic.com/news/2012/04/120411-drug-resistance-bacteria-caves-diseases-human-health-science/

Deep in the bowels of a pristine New Mexico cave, microbiologists have discovered nearly a hundred types of bacteria that can fight off modern antibiotic drugs.

The bacteria coat the walls of the Lechuguilla cave system on rock faces some 1,600 feet (487 meters) below Earth's surface. Until recently, the microscopic life-forms had encountered neither humans nor modern antibiotics.

That's because a thick dome of rock isolated the cave between four and seven million years ago. Any water that trickles through takes roughly ten thousand years to reach the cave's depths—which means the subterranean life has existed entirely in the absence of modern medicine.

While not infectious to humans, the cave bacteria can resist multiple classes of antibiotics, including new synthetic drugs. The discovery serves as an intriguing lead in the quest to understand how drug-resistant diseases emerge.

Or ejecta from an earth impact was sent to Mars.

He did say that maybe Viking might not have dug deep enough. Here, listen to the recording. It might help:

Have a nice day.

"I didn't build that damned thing to fail," my irascible father has been saying for 36 years about the Labeled Release experiment.

It's been a little sad, seeing him on the outside of that issue for half his life, being the only guy in the room who knew exactly what the experiment was, how it was built, how it was used, and what set of circumstances could have produced the result.

But, then again, he doesn't want to believe me when I tell him that the 9/11 terrorists showed up on Jack Abramoff's casino boat a week before the attacks.

So I guess we're even.

I've asked my old man if he knew Gil Levin, but he can't remember him. Levin's objectives were dispersed among many sub-contractors and design teams--hundreds of people on the biological instrument package alone, I am sure.

My old man's specific assignment was figuring out how to miniaturize an entire chemistry lab so that it could fit in a beer cooler--not such an easy thing to do in a day when a computer as fast as the one I built five years ago took up an entire floor of an office building.

Being a former Apollo engineer, Dad took the same ethical approach to his work on Viking: this thing isn't going to fail because of me. Other unknown and unpredicted factors can and will certainly intervene, he says, but the instrument itself was not in error.

I write this with my feet resting on the very launch pad my father built for me in the late 1960s--a coffee table built arm-high for a toddler, every sharp corner rounded off, with little sculpted indentations around the edges for a chubby little hand to grip. My father built this table specifically as the apparatus from which I would take my first steps, before I was born, and it worked precisely as he designed it, while he watched from his mission control on the couch.

That is the sort of engineer's certainty my father has about the Viking results, and he is certainly not alone among the Viking scientists and engineers.

This is an interesting analysis but there are some major flaws - the original Viking tests involved measuring gas composition emitted from samples of moistened martian soils. Since the time of the Viking Lander we've now gained a great deal of headway on the composition of the surface soils and with that knowledge now understand why we got results that were noisy.

We've found that the martian surface contains perchlorates, perchlorates on earth are used as oxidizers in chemical processes, explosives and solid fuel rocket engines. They are a source of oxygen!

Given the character of the tests conducted, if perchlorates were present in the soil samples they would have given either erratic or false positive results.

We'll know much more when Curiosity lands in August - this will the first time we will have put down a well equipped geochemical lab on the martian surface.

Putting a biological lab on the surface will be a help but before we do that we need as clear a picture of the geochemistry of the planetary environment.
