abstract = {Regolith draws intensive research attention because of its
importance as the basis for fabricating materials for future
human space exploration. Martian regolith is predicted to
consist of defect-rich crystal structures due to long-term
space weathering. The present report focuses on the
structural differences between defect-rich and defect-poor
forsterite (Mg2SiO4) – one of the major phases in Martian
regolith. In this work, forsterites were synthesized using
reverse strike co-precipitation and high-energy ball milling
(BM). Subsequent post-processing was also carried out using
BM to enhance the defects. The crystal structures of the
samples were characterized by X-ray powder diffraction and
total scattering using Cu and synchrotron radiation followed
by Rietveld refinement and pair distribution function (PDF)
analysis, respectively. The structural models were deduced
by density functional theory assisted PDF refinements,
describing both long-range and short-range order caused by
defects. The Raman spectral features of the synthetic
forsterites complement the ab initio simulation for an
in-depth understanding of the associated structural
defects.Keywords: Martian forsterite; crystal structures;
