Weird stuff on Mars !!!

Oh for Christ's sake! Well whether they "feel like it" or not, they should!

As usual JPL doesn't give any indication of scale or size of those objects
in the caption.

I expect they don't feel like repeating the same information over and over. The
microscopic imager has a fov of 31mm x 31mm, and an image scale of 30um/pixel.
It's a fixed focus device, so every image has the same scale.

looks like micro volcanic or heat deposited glass beads of some kind.
note the sharp fracturing & pitting on several which is characteristic
of such materials found in nature, but Im liklely wrong.

Why? It isn't their business to provide public annotation for every image they
collect. This is a scientific expedition, with a fairly short window of data
collection. The investigators are under no obligation to provide any short-term
information at all. They've done a good job of providing press releases
highlighting key events and finds, and provided a great courtesy in releasing so
many raw images. By virtue of its public funding all of the raw data will be
available in short order, and the specifications of all the instruments are
already available. Lighten up.

I didn't see any info on the magnification in use. Anyone have further
info?

FOV of microscopic imager is 31mm x 31mm. "EFF" in file name indicates full
frame.

That's what my guess would be, too. I've seen similar glass-bead
spherules,
having resulted from meteor impact heat on the moon in one of my astro
books.

But those moon beads are tiny ( 300 microns) and black. These are ~5000
microns and appear to have a matte surface?

You are way over the fence on this one. You should lighten up. It is
standard geological fare
to provide actual measurement scale in any photo of a geologic feature. The
least they
could do is tell us what the millimeter dimentions of the feature s are.
They did say once that
the Opportunity outcrop features were measured at 4 inches high.
