The evolution of organic material on Asteroid 162173 Ryugu and its delivery to Earth [PDF]
Nature CommunicationsThe recent return of samples from asteroid 162173 Ryugu provides a first insight into early Solar System prebiotic evolution from known planetary bodies. Ryugu’s samples are CI chondrite-like, rich in water and organic material, and primarily composed of H. G. Changela, Y. Kebukawa, L. Petera, M. Ferus, E. Chatzitheodoridis, L. Nejdl, R. Nebel, V.

Sci AdvThe Hayabusa2 spacecraft delivered samples of the carbonaceous asteroid Ryugu to Earth. Some of the sample particles show evidence of micrometeoroid impacts, which occurred on the asteroid surface.Matsumoto M, Matsuno J, Tsuchiyama A, Nakamura T, Enokido Y, Kikuiri M, Nakato A, Yasutake M, Uesugi K, Takeuchi A, Enju S, Okumura S, Mitsukawa I, Sun M, Miyake A, Haruta M, Igami Y, Yurimoto H, Noguchi T, Okazaki R, Yabuta H, Naraoka H, Sakamoto K, Tachibana S, Zolensky M, Yada T, Nishimura M, Miyazaki A, Yogata K, Abe M, Okada T, Usui T, Yoshikawa M, Saiki T, Tanaka S, Terui F, Nakazawa S, Watanabe SI, Tsuda Y. +38 moreeuropepmc +2 more sourcesSurface Ages for the Sample Return Asteroids Bennu, Ryugu, and Itokawa

The Astrophysical Journal Letters, 2022 Abstract We have conducted a NanoSIMS-based search for presolar material in samples recently returned from C-type asteroid Ryugu as part of JAXA's Hayabusa2 mission. We report the detection of all major presolar grain types with O- and C-anomalous isotopic compositions typically identified in carbonaceous chondrite meteorites: 1 silicate,Barosch, Jens, Nittler, Larry R., Wang, Jianhua, O’D.
