Mantle drilling, in which the oceanic crust is penetrated across the Moho to retrieve mantle samples, is one of the most challenging scientific projects of this century. This paper presents a literature survey on the development of mantle drilling, provides a brief introduction to mantle drilling, and introduces three drilling site candidates. Obstacles to mantle drilling are then presented, along with current R&D activities, plans, and considerations for solving those problems. For the purposes of this paper, significant contributions in mantle drilling research have been classified into the following categories: ultra-deep water, deep penetration, hard rocks, and high temperature. Necessary future research directions for mantle drilling are also described.
