[PPS07-07] Assessing the Small carry-on Impactor debris operated by the Hayabusa2 mission: an evaluation by FT-IR, micro-Raman, STXM and NanoSIMS.
Keywords:Hayabusa2 mission, Small carry-on Impactor
The explosion products generated by their chemical reactions with HMX, HTPB, IDP and IPDI should be investigated prior to analysis of the Ryugu samples because those materials might be possible contaminants in the subsurface samples in the sample container. It is, therefore, necessary to analyze the SCI fragments and its products using the same analysis techniques. These results will provide relevant information to the initial analysis in advance the arrival of the Ryugu samples to the Earth.
In this study, we will report analytical results of the experimental explosion-products of the HMX mixture under Ar condition utilizing an optical microscope for micrometer-scale texture, SEM-EDS for texture and major elements, microFT-IR for functional groups, micro-Raman for structures of carbonaceous materials, STXM (Scanning Transmission X-ray Microscopy) for sub-micrometer-scale functional groups of carbon, nitrogen and oxygen, and NanoSIMS (nano-scale Secondary Ion Mass Spectroscopy) for hydrogen, carbon and nitrogen isotopes.
