Martians may have already landed on Earth, at least in ancient microbial form. The same NASA team that discovered the controversial Allen Hills meteorite has shared new data that points to a biological origin for structures within the Martian rock, Spaceflight Now reports. NASA headquarters plans to officially address the new findings within days.
The Allen Hills meteorite sparked a huge debate in 1996 when both NASA and the White House announced the possible discovery of life from the red planet. President Bill Clinton gave a speech at the time that could perhaps sound prescient, if the new findings put scientific doubts to rest.
"It speaks of the possibility of life. If this discovery is confirmed, it will surely be one of the most stunning insights into our universe that science has ever uncovered," Clinton said.
The NASA scientists have recently scrutinized the meteorite with advanced High Resolution Electron Microscopy, and looked specifically at carbonate discs and magnetite crystals. They found that the structures show a chemical purity much more similar to a biological rather than geological signature, and have strong resemblance to so-called magnetic bacteria on Earth.
Scientists from NASA's Johnson Space Center in Houston have detailed their findings in the November issue of the journal Geochimica et Cosmochimica Acta. But other astrobiologists at NASA Ames Research Center near San Francisco and at the Jet Propulsion Laboratory in Pasadena have also been buzzing over the possible findings, according to Spaceflight Now.
Perhaps Earth may soon have a better answer to its longstanding questions about extraterrestrial life. If so, the War of the Worlds invasion tally is Mars 1, Earth 0.

Mars 1, Earth 0.
Can we be so naive as to think that we haven't already contaminated Mars with our space probes already?
Mars may have taken an early lead but Earth is rapidly catching up.
I thought about that -- it's definitely possible for Earth microbes to have survived the trip to Mars on spacecraft, but the astrobiologists that I've spoken to agree that the current Martian surface is extremely hostile to biological survival. But you're right that Earth is doing its best to catch up.
let's see where bible fits in this :-). Please run these type of articles thru church or religious entity before you publish..LOL..
"let's see where bible fits in this :-). Please run these type of articles thru church or religious entity before you publish..LOL.."
that's a joke right? because this is a science website, religion doesn't belong here.
not to mention, I don't care to read religion stuff on a website dedicated to science and technology.
If that is one rock that Landed on Earth and was found to have once harbored life..... and ...... we found it. Wouldn't that fact alone give you a better idea of how massive the interchange between all the planets are? I hardly think that one has more exposure to the other, I can imagine that all the planets have been churning out these types of meteorites as long as matter has been in existence.
Problem is, it only "points to" a biological origin as one possibility. Can neither confirm nor deny. There's an awful lot of work to do and questions to answer. For example, if there was microbial life on Mars, how did it get there? If microbes created the structures in the meteorite, did it happen before or after it struck Earth; in other words did earthly microbes create the structures? If they were created by microbes on Mars, did any of the microbes survive whatever cataclysm launched them into space? Did they survive the journey through the vacuum of space covering many months or years and millions of miles? Seems a little difficult to believe that microbes from Mars could have seeded life on earth, but it's fun to speculate.
Cookiees453: obviously ardas1968 was kidding.
Not only was that evident by the use of sarcasm, ardas1968 gave one not intelligent enough to understand sarcasm at least two obvious clues: (1) the use of a smiley face and (2) the use of the acronym "LOL".
Geeezzz - lighten up a little!
Surely its biological and it did survive the trip, just look at the religious folks, they're still alive and kicking to this day. :-)
also @ cookiees... Even pop sci, the people who run this website that you say shouldn't have any religious talk, did an article on religion. Its common knowledge that SCIENCE AND RELIGION DO NOT CONTRADICT EACH OTHER. You can pick one or the other and stick with it, but that doesnt mean the person on the other side of the conversation is wrong. How anal are you that someone JOKES about religion and you get offended.
If you think religion should be banned, then go away. Pop sci is about being open-minded and investigative. It's NOT about telling people what they can or cannot post in a comment.
This makes the finding at the Phoenix Lander even more interesting; scientist said that they found all the necessary nutrients to sustain life there. That is why these time lapse images that show something crawling around in the Phoenix Landers microscopic imager, one with a scorpion-like tail, even more intriguing….
possible life on mars, huh. that settles it then. we should pre-emptively bomb the s*** out of mars just in case. don't want them aliens getting any ideas.
Okay folks,heres a few tid bits from my science department.Earth and mars are our habitable spheres in this quadrant,they both have 24 hour days. before a system explosion long ago,mars was teeming with its ecosystem and human beings.
Now think about what would happen if system scientists(Thats us) shut down the grid field to 40 percent heating and gas input and you have a barren planet.
Now think about all that red dirt,just like the southwest here and you have the facts of life aboput copper miningg,here and there.
All genetic races and eco-system components came here and there in a lifter,we are the last system to be built in the super-universes.
99.9999 percent of you folks could not spot a lifter field here because they do not want to be seen,because of the very bad things those contingents do that would alter their mission here,(Metal ,again).
Guys from my department can explain the universe pretty good,but that is about a million times better than your favorite astro guruu,who knows nothing,for a reason.
Gravity is very simple also,and no I do not take meds,Im just the grid science guy.And you're NOT.
You boys should save your money,whatever you really need to know about mars or other spheres is right here on this sphere,but you wont stop,as some foolish agency is paying you boys from the publics money to spin and spin and spin the place to death whilst people in the know laugh and laugh and laugh at you.If you desire to know how the universe works,you must task a science man who understands the grid,and that does not mean Con-Edison,either.
When a planet explodes 28 thousand ago,we get the remnants in various periodicities that bring us the core components as cometary showers and energetic fields that create our excess weather and magma warming,and that takes a guy like me to explain that to he foolish IPCC and company fools,but they and obviously "YOU TOO" but they (the IPCC) cannot be overridden as they are well convinced that they understand the whole universe and that certain faction wants it that way to fulfill their agenda.
There are no tier 1 scientists at any university on this earth,I assure you.
Mars people were brought here 14 thousand years ago and the large mass of exploded components damaged the system to the point that the earth had to have a moon towed in to create a pull that slows it to its proper speed. Chew on these statements for a bit.
