I am interested in conducting a research project involving the design of a tool to aid astronauts to perform experiments on lunar surfaces (for the NASA Micro-g NExT student challenge), but I do not know appropriate key words or questions to ask to begin my research. The specific scenario of focus is to design a tool that can act as an anchor in a sand-like medium (regolith) on the surface of the moon; therefore, maximizing the resistance of the tool while buried underneath the sand is the principle goal. Is this design problem related to fluid mechanics, and if so, what sub-discipline of fluid mechanics is concerned with modelling the behavior of dry, granular media such as sand? Are there any specific disciplines or key-words within astrophysics that are closely related to this question? My initial concept is to design a type of drill that can lodge itself into the sand; considering this concept, what are some important variables to consider (i.e. weight of the tool, surface area of the drill, etc.)?
