Did I miss any news? "The spheres may have formed when molten rock was sprayed into the air by a volcano or a meteor impact." - Wikipedia (your link)

My original: "My first thought would be sphericles created by the liquifying of the rock when the meteor struck. They'd form into sphericles, then harden before landing."

My question concerned their uniformity of size!

If I set the budget, we'd have Ares and more. Unfortunately, I don't set the budget, and Ares is just too expensive and too far out for us to accomplish our goals within the budget we were given.

If we halt the ISS, all versions of Ares, and transport Orion and Altair aboard DIRECTv3's Jupiter family of Shuttle-Derived Launch Vehicles, we just might make it back to the Moon by 2020.
