Avalanche on an asteroid !?

The DART spacecraft revealed that Didymos exhibits a top shape with a bulging equator. The results of numerical simulation using a supercomputer were presented regarding the formation process of the top shape, which can also be seen in the Ryugu explored by Hayabusa2 and the Bennu explored by NASA/OSIRIS-Rex. The results show that such shapes can be formed by avalanches occurring on asteroids. For more details, refer to the article below. ◆ISAS GATE◆ 【Avalanche on an asteroid!?

Avoid celestial bodies colliding with Earth!

In this talk we introduced the current status of planetary defense (space guard) that deals with the celestial collisions with the earth. We discussed JAXA’s activities, including observing near-Earth objects and the Hayabusa2# and Hera-JAPAN projects as well as overseas activities such as DART/NASA and at the United Nations. We provided an overview of these topics, as well as the basics of planetary defense, so that everyone can understand.  This includes using 3D models to explain the thermal infrared imager, TIRI, that is being developed for Hera-JAPAN. Presenter: Makoto Yoshikawa (JAXA),  Speaker: Seitaro Urakawa(Japan Spaceguard Association), Toshifumi Yanagisawa (JAXA), Yuya Mimasu (Hayabusa2#/JAXA), Takuya Ishizaki, Yuri Shimaki (Hera-JP/JAXA). Streamed at JAXA Shagamihara online open campus 2022 (Oct. 21, 2022). Hera-JAPAN Nov. […]

Online open campus 2022

We provided the latest information on the Hera-JAPAN project at the JAXA Sagamihara online open campus 2022 (October 21, 2022) . Brian May, doctor of astrophysics who is also the guitarist of the legendary rock band Queen, talks about the mission. There were also discussions on the current status and science behind TIRI, the thermal infrared camera being developed by Hera-JAPAN. Please take a look! Presenter: Takuya Ishizaki (Hera-JP).
