“…The species and the abundance of amino acids on our witness coupons are similar to what was found on those reported by the NASA/JSC OSIRIS-REx team (Dworkin et al 2018;McLain et al, 2015, Contamination Knowledge Report JSC Curation Cabinets, personal communication). The NASA/JSC OSIRIS-REx team investigated the contamination level of cabinet desiccator boxes located in an ISO 7 cleanroom at Johnson Space Center (JSC) that were reserved for the storage of OSIRIS-RExreturned samples.…”

“…The difference in the common species of amino acids between the two facilities may be attributed to the origins of the contaminants. Through luminosity analysis, Dworkin et al (2018) found that the total abundance on the NASA/JSC witness plates could not be explained only by the presence of viable cells on the witness plates. Thus, several other organic materials in the cleanroom could also have been the source of the amino acids.…”

“…The total contamination level in the ESCuC of 0.3-1.2 ng/cm 2 (blank-corrected) is comparable to that in the NASA OSIRIS-REx team curation cabinet, 0.05-0.8 ng/cm 2 . Dworkin et al (2018) concluded that the contamination level of the NASA/JSC curation cabinet was satisfactory enough to receive samples. In the OSIRIS-REx mission, they set up a contamination requirement for amino acids at 180 ng/cm 2 .…”

“…Amino acids are the building blocks that make up proteins, and they exist everywhere in the terrestrial environment and can thus easily become incorporated into samples. Amino acids were also used as a target species to track organic contaminants in the OSIRIS-REx mission (Dworkin et al 2018).…”

The Hayabusa2 mission aims to obtain pristine samples from a near-Earth carbonaceous-type (C-type) asteroid, 162173 Ryugu, and return them to Earth. One of the scientific goals of the mission is to understand the origin and evolution of organic materials through the interactions between water and minerals in the early solar system. Thus, organic materials are the main focus of the analysis on the returned samples. The analysis of extraterrestrial organic materials, however, requires great care to avoid the introduction of terrestrial contaminants and artefacts to the samples. To investigate the potential for contamination, we performed an assessment through the amino acid analysis of witness coupons that were exposed in a clean chamber in an Institute of Space and Astronautical Science/Japan Aerospace Exploration Agency (ISAS/JAXA) curation room. In the study, the witness coupons were collected at different time periods, between 1 day and 1 month, to examine the accumulation rates of the contaminants. Seven common terrestrial amino acids (glycine, alanine, valine, leucine, isoleucine, proline, aspartic acid and glutamic acid) were detected on the witness coupons. Among them, glycine was found to be most abundant, with the highest concentration of 10 pmol/cm 2 detected on the day 7 witness coupon. Alanine was found in the next highest concentration, approximately one-third that of glycine. A time-dependent profile in terms of the increasing trend observed in the concentration from days 1 to 7 was found. The contaminants were considered to have multiple origins. Our results are similar to those reported by the National Aeronautics and Space Administration/Johnson Space Center (NASA/JSC) OSIRIS-REx team, which indicates that the quality control against terrestrial contaminants in our facility is at the same quantitative level as in their facility. The knowledge obtained on the contaminants in this study will provide important information for the curation procedure of the Hayabusa2-returned samples.

Carbonaceous materials in the sample catcher of the Hayabusa spacecraft were assigned as category 3 particles. We investigated the category 3 particles with a suite of in situ microanalytical methods. Possible contaminants collected from the cleanrooms of the spacecraft assembly and extraterrestrial sample curation center (ESCuC) were also analyzed in the same manner as category 3 particles for comparison. Our data were integrated with those of the preliminary examination team for category 3 particles. Possible origins for the category 3 particles include contamination before and after the operation of the Hayabusa spacecraft.
