Characterization of Regolith And Trace Economic Resources (CRATER): An Orbitrap‐based laser desorption mass spectrometry instrument for in situ exploration of the Moon

Rationale Characterization of Regolith And Trace Economic Resources (CRATER), an Orbitrap™‐based laser desorption mass spectrometry instrument designed to conduct high‐precision, spatially resolved analyses of planetary materials, is capable of answering outstanding science questions about the Moon's formation and the subsequent processes that have modified its (sub)surface. Methods Here, we describe the baseline design of the CRATER flight model, which requires
