Glad we're on our way again, but still wish we'd gotten a closer look at the bright 'slab' seen at the top of this image...

Looks like a wide area of fracture fill... or rind... or crusty, um, stuff covering it...

Oh well, one of the mysteries to be studied and solved by the next visitors to this area.

"New" images of Concepcion today... Oppy must have been having a clear out... Looks like she did get a closer look at that slab...thing... after all...

Hey - that is the best view of the crater yet. Very nice.

Cool, Chocolate Hills from the back...(first clearing, top left of edge of crater)

New MRO image of Oppy at the crater, nice to see she remains in their sites!

JPL Report on "Odd Material" on Concepcion ejecta

Looks like our speculations on the 'crack fill' exposed at Concepcion were in the right ballpark. Unfortunately, the spectrometry seems not to have made a critical distinction between pre- and post-impact formation of the material. I suppose parsimony favors the pre-impact diagenesis, but we may never know.
It would be very nice if we could visit another very young crater to make comparisons.

Time for an LCROSS-like mission to Meridiani coupled with a rover visit? Can't get younger than a brand-new crater!

And you'd have the bonus of imaging the entry and impact from the ground!
