Two Ryugu papers published in Science by Soluble Organic Matter and Organic Macromolecule Teams of the Initial Analysis Team.

Soluble Organic Matter Team, a sub-team of the Hayabusa2 Initial Analysis team has published the research results in the US journal, Science. The team analyzed organic molecules extracted from the Ryugu surface samples, and revealed their organic molecule compositions. Moreover, the team discussed the potential transportation of the observed molecules throughout the Solar System.

Organic Macromolecule Team (led by Prof. Yabuta Hikaru, Hiroshima University), a sub-team of the Hayabusa2 Initial Analysis team has published the research results in the US journal, Science. The team examined the chemical, isotopic, and morphological compositions of macromolecular organic matter in samples of the asteroid Ryugu, and first proved that the direct link between macromolecular organic matter in the carbonaceous asteroid and that in primitive carbonaceous chondrites. Moreover, the paper discussed the potential contributions to the formation of habitable planetary environments.
