Mars rover discovers mysterious 'blueberries'
Source: The Age (Australia)
NASA's Opportunity rover, older brother to the Curiosity rover that landed on Mars last month, has made a discovery that geologists find both puzzling and exciting, the US space agency says.
Opportunity, which has been on the Red Planet since 2004, has come across an outcrop of tiny spheres - up to around three millimetres in diameter - the likes of which scientists have never seen.
"This is one of the most extraordinary pictures from the whole mission," said Opportunity's principal investigator, Steve Squyres of Cornell University in Ithaca.
"We never have seen such a dense accumulation of spherules in a rock outcrop on Mars."
At first glance, the researchers thought the objects resembled iron-rich spheres, nicknamed "blueberries", discovered near the Opportunity landing site.

You can see them in a NASA photo with a magnifying glass as they fall into upper atmosphere. It was only the damnedst bit of luck yet, in the space program, that they landed near Opportunity's site, half way round Mars, and now look like blueberries. It'll be centuries before they develop the technology to reconstruct them and read them.

Even before marble-shaped pebbles nicknamed ?blueberries? were discovered on Mars by the Opportunity rover, University of Utah geologists studied similar rocks in Utah?s national parks and predicted such stones would be found on the Red Planet.
In a study published in the June 17 issue of the journal Nature, the Utah researchers suggest both the Martian and Utah rocks ? known as hematite concretions ? formed underground when minerals precipitated from flowing groundwater.
?We came up with the ?recipe? for blueberries,? says Marjorie Chan, chair and professor of geology and geophysics at the University of Utah. ?Before Opportunity landed, we thought there might be hematite concretions on Mars. That was based on our study of hematite-rich regions of southern Utah, where hematite balls are found in national parks and have long been a geological oddity that shows up in many rock shops.?
The round rocks are found in southern Utah in Zion and Capitol Reef national parks, Grand Staircase-Escalante National Monument, Snow Canyon State Park and the Moab area.

(16,230 posts)The so-called Martian blueberries are formed when minerals separate from water and become hard masses inside sedimentary blocks - they're part of the evidence Mars used to be wet.
But closer investigation revealed the new discoveries are "different in concentration. They are different in structure. They are different in composition. They are different in distribution," Squyres said.

(10,857 posts)1) They are "iron rain," droplets of molten iron and silicon ejected from an enormous impact by an iron-rich asteroid. The droplets solidified after minutes or hours of falling back to the surface;
2) They are ooids, not quite like the CaCO2 ooids that form around shell fragments in our oceans, but formed in a similar way, which suggests large bodies of open water and regular wave action.
I should add that I have barely any idea what I'm talking about, but I cannot help guessing anyway.

(1,843 posts)sound like you know exactly what you are talking about. I think you give yourself too little credit on this one.

Magic underwear, golob/kolob, angel macaroni, how many wives j smith had , why granddad had to go to mexico. soooooo much, my head is going to explode. where are mitt-twits tax returns, why did I think america's racist-fascist-corporatist underbelly was gone. How stupid of me. So much to keep my eye on.
It's Kolob. It's a glob in the sky someplace.
but I do resent them sending their globules here to insult my intelligence.
