As my time in this is very limited, are there other precise matches, or similar possible inorganic growths which could be less endowed with the organic complex build of the 'rolling particle'?
What is the group name convention for the particle in particular/
Are geology trained persons prepared as yet to identify a common Earth sequence which could give this type of organic complexity to the multiple parted structure?
Are these a core of crystalline mass as a single material, layered by sheathings of other materials, or can the distinct tip point on both, and the general shape be chance?
Stu, I thank you for your patience. You've done very good work in presenting the particle to catch my eye. That's really cute color imagery, as is the work of Horton, LWS, mann, and the many others who work hard here.
Can this be a motive for additional landers, possibly, in the polar regions north and south? Perhaps another MRO satellite finish the work of the first?
