Beyond depth: Decoupling the astronaut from coring in crewed lunar drilling
-
ABSTRACT
Fifty years of lunar drilling—three crewed campaigns and a succession of robotic missions from Luna 24 to Chang’e-6—has converged on a consistent pattern: no coring architecture has yet preserved the uppermost stratigraphic interval intact while reaching multi-meter depth safely. The Apollo record, through the lens of engineering failure-mode insights, shows that coupling the astronaut’s body into the drill’s load path was the common root of its extraction, stratigraphic, and thermal disturbances. The robotic record shows the mirror image: crew risk was eliminated, but reliable penetration stalled near one meter and, even in the deepest success of Luna 24, the top 50–60 cm of the core returned empty. As China prepares for a crewed lunar landing before 2030, we contend that the design question is not “astronaut or robot” but how completely a system decouples human presence and mechanical actuation from the geological record it seeks to preserve. We propose a functional-decoupling paradigm—load-path, operational, and stratigraphic decoupling—supported by early-stage prototype hardware now under development, and call for an explicit sample-integrity budget to stand alongside mass and power budgets in future mission design. -
