The Japan Aerospace Exploration Agency plans to launch a new organization Wednesday specializing in the study of extraterrestrial materials to further investigate how the solar system developed, agency officials said Saturday.

JAXA, as the agency is known, will establish the new organization within its Institute of Space and Astronautical Science in Sagamihara, Kanagawa Prefecture.

The group is expected to analyze mineral grains brought back to Earth from the asteroid Itokawa by the Hayabusa probe, as well as rocks taken from asteroid 1999 JU3 by the Hayabusa2, which is expected to arrive in three years and return with the samples by the end of 2020.
