| Outline of Final Research Achievements |
The present study performed exploratory research to investigate organic syntheses occurred within exo-oceans of icy bodies in the Solar system toward understanding of the mechanisms and variety of chemical evolution beyond Earth. By comparing the reflectance spectra of organic matter on Pluto obtained by the spacecraft with our laboratory experimental data, we show the occurrence of a giant impact and subsequent organic synthesis onto this icy dwarf planet in the early stage of its evolution. We also investigate shock-induced alterations of organic matter through hyper-velocity impact experiments, which is necessary for future sample-return missions to icy bodies in the Solar system.
