It depends. The White House's Office of Management and Budget doesn't see a need for such a mission. House appropriators, from both parties, clearly do – because they approved nearly $100 million more for planetary science (with cuts elsewhere to offset the increase)in NASA's budget than the White House did. The Senate has yet to say.

Numerical and experimental investigations on new jar ...

Planetary ball mill is a widely used apparatus to process almost any class of material, from metals and ceramics to organic com-pounds and pharmaceuticals [1–6]. The geometry of the device and its working principle are rather simple, with grinding occurring by impacts between milling media (balls and jar) and mill charge (see e.g. [1,7]).

Planetary Mills – fritsch.de - Milling and Sizing

Planetary Mills classic line process hard, medium-hard, soft, brittle, abrasive, fibrous and moist materials from a few milligrams up to several kilograms and achieve final finenesses of less than 1 μm. The comminution of the material to be ground takes place primarily through the high-energy impact of grinding balls in rotating grinding bowls.

Mill (grinding) - Wikipedia

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
