19:00～19:55 JST	Basics of planetary defense and JAXA's activities When celestial bodies like asteroids or comets collide with the earth, they cause very big disasters. We want to avoid such disasters, and the activity to avoid such disasters is called planetary defense or spaceguard. In this lecture we will explain the basics of planetary defense. Then, we will show what is being done at JAXA in relation to planetary defense. In particular, we will talk about discovery observations for small fast-moving objects and the Hayabusa2 extended mission. Dr. Makoto Yoshikawa, JAXA Dr. Yuya Mimasu, JAXA Dr. Toshifumi Yanagisawa, JAXA
20:00～20:55 JST	The ESA Hera mission: Rendezvous with binary asteroid Didymos and investigation of the DART crater On 26 September 2022 NASA's Double Asteroid Redirection Test (DART) spacecraft will impact Dimorphos, the satellite of asteroid (65803) Didymos. ESA's Hera spacecraft will rendezvous with Didymos four years after the impact. It will perform the measurements necessary to understand the effect of the DART impact on Dimorphos in detail, in particular by measuring its mass, and investigating its internal structure, and thus determining the momentum transfer and detailed characterization of the crater left by DART. Those investigations will be valuable for cratering physics in general, as Hera has the unique opportunity to study a crater for which the impactor properties are accurately known. Finally, as the first mission to a binary asteroid, Hera will study the mechanism of the formation of binary asteroids. Dr. Michael Küppers, ESA Dr. Patrick Michel, CNRS
21:00～21:55 JST	NASA's Planetary Defense Activities and the DART Mission NASA's Planetary Defense Coordination Office leads a number of planetary defense activities, including: detection, tracking, and characterization of near-Earth objects; coordination of planning and response actions; and strategies to mitigate potential future impacts with Earth. The Double Asteroid Redirection Test (DART) is one part of NASA's larger planetary defense portfolio and is the world's first full-scale planetary defense test, demonstrating one method of asteroid deflection technology. DART's target asteroid is no threat to our planet but is an ideal candidate for taking this first step to demonstrate asteroid deflection via a kinetic impactor. DART is on its way to collide with the asteroid Dimorphos on 26 September 2022; for more information, visit:https://dart.jhuapl.edu/. Dr. Nancy Chabot, Johns Hopkins University Dr. Thomas Statler, NASA
22:00～22:30 JST	Discussion Session Dr. Elizabeth Tasker (Moderator)
