Horta eggs!!
/ joke.

Hematite, malachite both can have spherical shapes, but not like that.
Not sure what those might be.
Honestly would have to see one cut in half and thoroughly analyzed.

there are some broken spheres laying around...I'm sure they'll be putting the microimager on them...it's going to be hard for these guys to leave this outcrop!

LOL, what's a "Horta".

Btw, take a look at the image with the red circle on the left above. There appear to be several sphere pieces, possibly the result of a fall to the ledge above.
