Hayabusa, Itokawa Sample Curatorial Dataset

Overview

Description

The contents of this dataset are mainly derived from initial description work a part of Itokawa sample curation by Astromaterials Science Research Group (ASRG).


JAXA’s Hayabusa (MUSES-C) spacecraft explored S-type near-Earth asteroid (25143) Itokawa（1998SF36）and successfully returned its reentry capsule on June 13, 2010.
When a cover of the sample catcher was opened in a nitrogen atmosphere and the inside of the catcher was observed with an optical microscope, particles of a size that could be seen with the naked eye were not found. After that, the sample catcher was moved to the second room, and as a result of scratching inside the catcher with a Teflon spatula, fine particles adhered. Electron microscopy (SEM) and energy dispersive X-ray analysis (EDS) showed that about half of the particles were aluminum fragments that had peeled off from the inside of the catcher. The rest were confirmed to be mineral particles such as olivine, pyroxene, plagioclase, etc., and were found to be derived from Itokawa.


A portion of the samples collected from the catchers are provided to universities and research institutes that are collaborating with ASRG. A variety of analyses, called initial analyses, have been conducted to gain insight into the existence of Itokawa’s parent body, the history of Itokawa formation, and the evolution of surface materials. JAXA has also exchanged a memorandum of understanding (MOU) with NASA and has provided part of the sample to NASA’s curation group.


The sample catcher has Room B in addition to Room A which was opened just after returning. In addition, there was also a mechanism called as a rotating cylinder, and particles believed to be from Itokawa were also attached to those parts. ASRG are still retrieving these materials.
