Asteroid Explorer Hayabusa2 Initial Analysis Chemical Analysis Team reveals aqueous alteration and primitive composition of asteroid Ryugu
The Hayabusa2 Initial Analysis Team is currently engaged in analysing the sample returned from asteroid Ryugu by the Asteroid Explorer Hayabusa2 Project. The Initial Analysis Team consists of six sub-teams and two Phase-2 curation institutions, Okayama University and the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) Kochi Institute for Core Sample Research.
A summary of recent results from the Chemical Analysis Team in the Hayabusa2 Initial Analysis Team has been published in the American scientific journal, “Science”, on June 10, 2022.
Samples returned from the asteroid Ryugu are similar to Ivuna-type carbonaceous meteorites
