MSL have found something "earthshaking," some data that is going "be one for the history books."

Scientists working on NASA's six-wheeled rover on Mars have a problem. But it's a good problem.

They have some exciting new results from one of the rover's instruments. On the one hand, they'd like to tell everybody what they found, but on the other, they have to wait because they want to make sure their results are not just some fluke or error in their instrument.

It's a bind scientists frequently find themselves in, because by their nature, scientists like to share their results. At the same time, they're cautious because no one likes to make a big announcement and then have to say "never mind."

The exciting results are coming from an instrument in the rover called SAM. "We're getting data from SAM as we sit here and speak, and the data looks really interesting," John Grotzinger, the principal investigator for the rover mission, says during my visit last week to his office at NASA's Jet Propulsion Laboratory in Pasadena, Calif. That's where data from SAM first arrive on Earth. "The science team is busily chewing away on it as it comes down," says Grotzinger.

SAM is a kind of miniature chemistry lab. Put a sample of Martian soil or rock or even air inside SAM, and it will tell you what the sample is made of.

Grotzinger says they recently put a soil sample in SAM, and the analysis shows something earthshaking. "This data is gonna be one for the history books. It's looking really good," he says.

EDIT : :derp:
NASA downplayed Wednesday talk of a major discovery by its Martian rover after remarks by the mission chief raised hopes it may have unearthed evidence life once existed on the Red Planet.

"John was delighted about the quality and range of information coming in from SAM during the day a reporter happened to be sitting in John's office last week. He has been similarly delighted by results at other points during the mission so far,"

"the whole mission is for the history books"

What Did Curiosity Find on Mars? Wait and See

I generally avoid articles like this because of all the wild speculation and sensationalism.
I am reminded of the Mono Lake hoopla. I think Phil Plait says it best in his blog:
OK, everyone, can we all take a sec and just breathe?

I’m getting emails, and seeing Facebook updates, blog posts, and tweets—and I bet if I look hard enough, even smoke signals—about scientists saying they’ve found something “for the history books” on Mars. This was first reported by NPR in an interesting but nearly meatless article. All we know is that the scientists who are running an instrument on the Curiosity rover called SAM—for Sample Analysis on Mars, an apparatus that can analyze material scooped up from the surface—are very excited about some preliminary results.

Very excited. John Grotzinger, the Project Scientist for Curiosity, said in an interview, "This data is gonna be one for the history books. It's looking really good."

And that’s all we know. We don’t know what they found. We don’t even know what sort of thing they’ve found: geologic, biologic, chemical, atmospheric, or what. We do know that Dr. Grotzinger is excited, but wants to make sure the results are valid before announcing them.

Hmmm!! What's your guess as to what SAM has found? :shock:
I'm guessing something related to the building blocks of life! :?
Anyway; I'm hoping is cool! :D 8-)

Mission scientist for the Mars Science Laboratory, Dr. John Grotzinger, talks to SPACE.com about how the instrumentation on the rover made the find that he calls “one for the history books”.

Results to be announced early December :!:

NASA Fends Off Mars Organics Rumors
Discovery News | Ian O'Neill | 2012 Nov 29
"Rumors and speculation that there are major new findings from the mission at this early stage are incorrect," a NASA statement reads. "At this point in the mission, the instruments on the rover have not detected any definitive evidence of Martian organics."

Everybody Chill, NASA Says: No Martian Organics Found
Universe Today | Nancy Atkinson | 2012 Nov 29
“Everybody, chill,” Tweeted the Curiosity rover today. “After careful analysis, there are no Martian organics in recent samples.”

No, NASA Didn’t Find Plastic Beads on Mars

Curiosity Fully Analyzes First Soil Samples

Post by bystander » Wed Dec 05, 2012 1:09 am

Curiosity Fully Analyzes First Soil Samples
NASA | JPL-Caltech | GSFC | MSL Curiosity | 2012 Dec 03
NASA's Mars Curiosity rover has used its full array of instruments to analyze Martian soil for the first time, and found a complex chemistry within the Martian soil. Water and sulfur and chlorine-containing substances, among other ingredients, showed up in samples Curiosity's arm delivered to an analytical laboratory inside the rover.

Detection of the substances during this early phase of the mission demonstrates the laboratory's capability to analyze diverse soil and rock samples over the next two years. Scientists also have been verifying the capabilities of the rover's instruments.

Curiosity is the first Mars rover able to scoop soil into analytical instruments. The specific soil sample came from a drift of windblown dust and sand called "Rocknest." The site lies in a relatively flat part of Gale Crater still miles away from the rover's main destination on the slope of a mountain called Mount Sharp. The rover's laboratory includes the Sample Analysis at Mars (SAM) suite and the Chemistry and Mineralogy (CheMin) instrument. SAM used three methods to analyze gases given off from the dusty sand when it was heated in a tiny oven. One class of substances SAM checks for is organic compounds -- carbon-containing chemicals that can be ingredients for life.

"We have no definitive detection of Martian organics at this point, but we will keep looking in the diverse environments of Gale Crater," said SAM Principal Investigator Paul Mahaffy of NASA's Goddard Space Flight Center in Greenbelt, Md.

Curiosity's APXS instrument and the Mars Hand Lens Imager (MAHLI) camera on the rover's arm confirmed Rocknest has chemical-element composition and textural appearance similar to sites visited by earlier NASA Mars rovers Pathfinder, Spirit and Opportunity.

Curiosity's team selected Rocknest as the first scooping site because it has fine sand particles suited for scrubbing interior surfaces of the arm's sample-handling chambers. Sand was vibrated inside the chambers to remove residue from Earth. MAHLI close-up images of Rocknest show a dust-coated crust one or two sand grains thick, covering dark, finer sand.

"Active drifts on Mars look darker on the surface," said MAHLI Principal Investigator Ken Edgett, of Malin Space Science Systems in San Diego. "This is an older drift that has had time to be inactive, letting the crust form and dust accumulate on it."

CheMin's examination of Rocknest samples found the composition is about half common volcanic minerals and half non-crystalline materials such as glass. SAM added information about ingredients present in much lower concentrations and about ratios of isotopes. Isotopes are different forms of the same element and can provide clues about environmental changes. The water seen by SAM does not mean the drift was wet. Water molecules bound to grains of sand or dust are not unusual, but the quantity seen was higher than anticipated.

SAM tentatively identified the oxygen and chlorine compound perchlorate. This is a reactive chemical previously found in arctic Martian soil by NASA's Phoenix Lander. Reactions with other chemicals heated in SAM formed chlorinated methane compounds -- one-carbon organics that were detected by the instrument. The chlorine is of Martian origin, but it is possible the carbon may be of Earth origin, carried by Curiosity and detected by SAM's high sensitivity design.

"We used almost every part of our science payload examining this drift," said Curiosity Project Scientist John Grotzinger of the California Institute of Technology in Pasadena. "The synergies of the instruments and richness of the data sets give us great promise for using them at the mission's main science destination on Mount Sharp."
