For the Moon, space weathering causes reddening, darkening, and diminished contrast in reflectance spectra over visible and near-infrared wavelengths. The physical and chemical changes responsible for these optical effects occur on scales below the diffraction limit of traditional far-field spectroscopic techniques. Recently developed super-resolution spectroscopic techniques provide an opportunity to understand better the optical effects of space weathering on the sub-micrometer length scale. In this paper, we used a synchrotron-based spectroscopic technique with ∼20 nm spatial resolution to examine cross-sections from two mature lunar soils at midinfrared wavelengths (700–2000 cm−1; 5–14.3 µm). Our findings are broadly consistent with prior bulk observations and theoretical models of space weathered spectra of lunar materials. These results provide a direct spatial link between the physical/chemical changes in space-exposed grain surfaces and spectral changes of space-weathered bodies. 000000026 536__ $$cDE-AC02-05CH11231$$oUnited States Department of Energy 000000026 536__ $$oAdvanced Light Source Division of the Lawrence Berkeley National Laboratory 000000026 540__ $$aCreative Commons Attribution Non-Commercial Share Alike (CC BY-NC-SA) 4.0 International$$uhttps://creativecommons.org/licenses/by-nc-sa/4.0/ 000000026 650__ $$aPhysical sciences 000000026 6531_ $$aSpace Weathering 000000026 6531_ $$aInfrared 000000026 6531_ $$aNear-Field 000000026 6531_ $$aLunar Soil 000000026 655__ $$aTabular 000000026 7001_ $$aUtt, Kainen L.$$1https://orcid.org/0000-0002-8555-9000$$uWashington University in St. Louis$$4https://ror.org/01yc7t268$$5ROR 000000026 7001_ $$aOgliore, Ryan C.$$1https://orcid.org/0000-0001-8165-6252$$uWashington University in St. Louis$$4https://ror.org/01yc7t268$$5ROR 000000026 7001_ $$aBechtel, Hans A.$$1https://orcid.org/0000-0002-7606-9333$$uLawrence Berkeley National Laboratory$$4https://ror.org/02jbv0t02$$5ROR 000000026 7001_ $$aGillis-Davis, Jeffrey J.$$1https://orcid.org/0000-0002-4047-680X$$uWashington University in St. Louis$$4https://ror.org/01yc7t268$$5ROR 000000026 7001_ $$aJolliff, Bradley L.$$uWashington University in St. Louis$$4https://ror.org/01yc7t268$$5ROR 000000026 8564_ $$93366c560-066f-40bc-b516-613626df2047$$s52633190$$uhttps://data.library.wustl.edu/record/26/files/doi107936xavhag19_utt_dip.zip$$ePublic$$23cc4ced6d7d2631511f8e342eda1f906$$01 000000026 8564_ $$9704e3eaf-391b-41e9-a3aa-dd501e3162af$$s4940$$uhttps://data.library.wustl.edu/record/26/files/readme_utt.txt$$ePublic$$2d54435b011135ee44f6cd0281895cc70$$01 000000026 904__ $$arogliore@physics.wustl.edu 000000026 904__ $$ahabechtel@lbl.gov 000000026 904__ $$aj.gillis-davis@wustl.edu 000000026 904__ $$abjolliff@wustl.edu 000000026 909CO $$ooai:data.library.wustl.edu:26$$pdataset 000000026 974__ $$aMoon 000000026 980__ $$aWashU Researcher Data
