Fossils of Martian bugs found on meteorite that landed on Earth 13,000 years ago

“”Those Martian bugs are tough, they come back to life every few years when “discovered” again. It’s a cycle, “discover, debunk, discover, debunk”. It’s the Discover cycle. again.””

Reading the news release often helps.

New evidence has made it more likely that remnants of Martian microbes were transported to Earth in a meteorite, it was revealed today.

The discovery strengthens the case for believing that worm-like structures in the meteorite are ‘microfossils’ of ancient Martian bugs.

Sceptics have pointed out that similar-shaped structures could be formed from non-biological processes.

Another unanswered question is whether the microfossils were the result of contamination by Earthly bacteria. This was originally ruled out by Nasa but has raised doubts in the minds of other experts.

However, the excitement did not last long. Other scientists questioned whether the meteorite samples were contaminated. They also argued that heat generated when the rock was blasted into space may have created mineral structures that could be mistaken for microfossils.

The new study was conducted using advanced high resolution electron microscope techniques which were not available 13 years ago.

News of the findings, expected to be released soon by Nasa, was leaked to the space news website Spaceflight Now and picked up today by the Sun newspaper.

It focused on a more detailed analysis of magnetite crystals - tiny magnetic particles - and carbonate discs within the rock.

Certain bacteria on Earth are known to contain magnetite crystals, which they are believed to use as tiny compasses to help them navigate.

The crystals form unusual shapes when associated with bacteria which can be seen in ALH 84001, it is claimed.

In addition the scientists say the chemical purity of the features they studied points to biology rather than geology, and a possible interaction with water.

At first, I thought there might have been an error. I have no doubt about that now. I know there is no error.

‘The big question is can these things be reliable magneto fossils, and that is a matter of debate. But it turns out that the magnetic bacteria make some very unique shapes of magnetite crystals. And one of the organisms we work with on Earth makes particles that look virtually identical to what we see from Mars in the meteorite.’

Spaceflight Now said the data provided “a powerful new case” for believing the meteorite carried traces of extraterrestrial life, according to its sources.

The report added: ‘Although not a smoking gun, the new findings considerably strengthen the Mars life arguments that have been hotly and passionately debated for a decade, given that the discovery of life on Mars is the Holy Grail of science.’

NASA has spent billions of dollars to find life on Mars and will continue to spend billions more.

This is little more than hope and hype, maybe and might be.

Yes, reading the news release DOES help.

"...and how is it they know this came from Mars 13,000 years ago? Probably just more “religious science.”"

I find it incredulous that those with no scientific training beyond 9th grade Biology feel qualified to critique or form an opinion on this.

Those before you could have built easy chairs, instead of ships that sailed the oceans to unseen, uncharted new worlds.

This comment, coming from a being that lives on one of trillions of planets, a planet so tiny and insignificant, it' not even visible from it's closest star.

But if life could be found on Mars, (it seems to be the candidate of choice right now) it would supposedly prove life can arise if the chemistry is just right. That's the hope part.

“New evidence has made it more likely that remnants of Martian microbes were transported to Earth in a meteorite, it was revealed today.

A study by scientists from the American space agency Nasa has found chemical signatures in the rock strongly associated with life.

The discovery strengthens the case for believing that worm-like structures in the meteorite are ‘microfossils’ of ancient Martian bugs.”

That's the hype part along with the maybes and might be’s.

But who knows, another hundred billion or hundred trillion or gagzillion of dollars might do the trick.

Screw all that science and exploration...It would be a lot easier to lay on the sand, eat coconuts, carve tiki’s, and watch the palms sway in the breeze. All hail the Lizard God.

[backwoods-engineer]

From now on, all questionable science reports should be met with a reminder of the CRU scandal: “Hide the decline!” I for one will from now on be extremely skeptical of claims made by scientists, unless they are from “hard” experimental sciences like particle physics. No more “just so” stories, especially ones that call for a socialist planetary regime like “climate change” does...

Here is a result of some of that wasted money you referred to. Pretty cheesy huh?

Clouds above the rim of "Endurance Crater" in this image from NASA's Mars Exploration Rover Opportunity. These clouds occur in a region of strong vertical shear. The cloud particles (ice in this martian case) fall out, and get dragged along away from the location where they originally condensed, forming characteristic streamers. Opportunity took this picture with its navigation camera during the rover's 269th martian day (Oct. 26, 2004). (NASA/JPL)

First, it doesn’t have to be straight up. Escape velocity is scalar, not vector, as long as the direction isn’t straight at the ground. Proof that this can happen can be seen any night the moon is visible in the sky, as it’s the result of a Mars sized impact with the Earth.

Second, it didn’t need to point at the tiny spot in the sky thats the Earth, it just needed to enter the area of Earths gravitational field, which is pretty big, considering it’s the closest neighbor to Mars, and it had millions of years to be influenced by that gravitational field to finally fall to Earth as a meteorite.

You might want to learn a little science before you express your contempt for scientists.

Below is a result of more money being wasted on science and exploration.

It's all hype!!

On May 19th, 2005, NASA's Mars Exploration Rover Spirit captured this stunning view as the Sun sank below the rim of Gusev crater on Mars. This Panoramic Camera mosaic was taken around 6:07 in the evening of the rover's 489th martian day, or sol. Spirit was commanded to stay awake briefly after sending that sol's data to the Mars Odyssey orbiter just before sunset. The image is a false color composite, showing the sky similar to what a human would see, but with the colors slightly exaggerated. (NASA/JPL

Yep, it looks a fossil off of Venus to me!

Allen Hills (ALH) 84001, crashed onto the frozen wastes of Antarctica 13,000 years ago and was recovered in 1984.

Thanks hennie pennie. I still regard this thing as just a drum to beat in pursuit of human missions to Mars. :')

Cool! For the price of a Mona Lisa we get a nice picture. Of course I’m not paying for the Mona Lisa.

[Mr. K]

A rock blasting of into space from a meteor strike is extremely easy- forget that one- the math is so simple

Harder is identifying a rock here on earth as coming from Mars- but STILL very very easy - by comparison

Finding a microbe and identifying it as ancient life- that is the hardest of all- I would like to see more than this, but it does look promising

I don’t have the money to lay on beaches, I have to pay for those lovely, enhanced pictures. Probably just as well, one of NASA’s rockets might go off and land on me.

Mona Lisa? Is this your idea of a clever quip?

You compare a an oil painting to the historic American scientific exploration of another planet, using spacecraft and surface remote controlled vehicles that are the envy of the world, that returned volumes of scientific data, images and discoveries that enabled other mission to mars and beyond.

What did the Mona Lisa last sell for? I was thinking six or seven million dollars. Anyway I plainly said PRICE of same being compared to the PRICE of the picture.

Not sure if that’s accurate obviously, not knowing how Mars items are/if priced out individually. And there may be a discount for volume.
There is the added problem too that the bill hasn’t arrived yet.

“Mona Lisa? Is this your idea of a clever quip?”

Why no...Is it yours?
