Here's a link to today's image from Fram Crater, which shows lots of those same blueberry objects seen back at Opportunity's landing spot.

When asteroids strike, a whole lot of energy gets released along with the debris. I'm sure some of it liquifies as it is flying through the air. Maybe those blueberries are meteoric iron or something.

Well, now that I've looked at it, it may be something caused by water as they say. I think they have chemical evidence for that or something.

I think that is correct.

I'd take more than one!

Also, when asteroids strike, they can melt the sand around them into glass.

The point of the blueberries is that, based on their chemical signatures, they are believed to be concretions. Concretions are small spherical blobs of minerals that precipitate out of salty water. Hematite is a form of iron oxide that forms in water, and the bluberries are rich in hematite. Hence the salty sea theory for Meridiani Planum.

I've never heard of that, but thats not saying a whole lot. You seem to be very well versed in science, is that what your degree is in?

My first major in college was engineering, but I switched to business and now I'm an auditor. I still follow anything to do with physics, astronomy, and space, though. I also visit the Mars Exploration Rover site often to see the latest images and read the latest theories. There were also several news conferences carried by the regular news about this particular story and a Discovery channel special. It was hard to miss.

Wow. I'm still making my way through high school...

The 'Salty Sea theory for Meridiani' was announced as a direct result of the data returned from Opportunity; so it will be a few years before it makes it into schoolbook texts. To this point, the scientific community at large consideres the theory and the data behind it to be rock solid (pun intended) and accepted as an accurate description of that area of Mars at some point in the past.

Oh, I didn't even hear anything about it in the daily mail from universe today.
