In conjunction with the “Double Sample Exhibition of Asteroids Itokawa and Ryugu,” held from May 10 to May 18at the Yamanashi Prefectural Science Center, Professor Shogo Tachibana of the University of Tokyo Organization for Planetary and Space Science (UTOPS) delivered a public lecture.

The international workshop “Hera, Apophis T-4, and RAMSES in Tokyo 2025” was held at the Koshiba Hall, Hongo Campus, The University of Tokyo, from April 7 to April 11, 2025.
The workshop brought together researchers working on planetary defense and the exploration of small bodies, including the Hera Community Meeting 2025, the Apophis T-4 meeting, and the first RAMSES Community Meeting, providing an opportunity for discussions on current research and mission activities related to planetary defense.

The Tachibana Laboratory at UTOPS has signed a joint research agreement with ALE Co., Ltd. (https://star-ale.com/), a company whose mission is to “make space closer for all of us together”, for an exploration mission to the asteroid “99942 Apophis”.
[Comments]Shogo Tachibana, Professor, University of Tokyo Organization for Planetary and Space Science (UTOPS), Graduate School of Science, The University of Tokyo:
“Recent missions such as Hayabusa2 and NASA’s OSIRIS-REx have shown that asteroid surfaces are highly diverse. This method will enable us to investigate the properties of surface materials at multiple locations on an asteroid. It is expected to contribute significantly to solar system science, planetary defense, and the utilization of space resources. The approach may also be applied to various future exploration missions, and I look forward to the progress of this joint research.”
