Hayabusa2, Ryugu Sample Curatorial Dataset

The contents of this dataset are mainly derived from initial description work a part of Ryugu sample curation by Astromaterials Science Research Group (ASRG). JAXA’s Hayabusa2 spacecraft explored C-type near-Earth asteroid (162173) Ryugu and successfully returned its reentry capsule on December 6, 2020. Particles exceeding ~5 grams in total were safely extracted from two sample chambers (A and C) of the sample catcher in the clean chamber system dedicated to Ryugu samples in the curation facility in JAXA. A series of initial description work has been conducted in the clean chamber without exposure to the air by curatorial staffs, and its results are catalogued in this dataset [1]. This dataset includes results from measurements with an optical microscope, a balance, a FTIR spectrometer, a hyper spectral infrared imaging system called MicrOmega [2], and an optical multi-band imager with filters compatible with Hayabusa2 optical navigation camera (ONC) [3].
