Lunar Impact Flash Study by Ground-based Telescopes, Laboratory Experiments and the 6U Spacecraft / Prof Shinsuke Abe (阿部新助 教授) (Department of Aerospace Engineering, Nihon University)  

Abstract: The lunar impact flash observing camera "DELPHINUS" onboard the 6U
spacecraft EQUULEUS, developed in collaboration with Nihon University,
the University of Electro-Communications, the University of Tokyo, JAXA,
and major manufacturers, has been launched on November 16, 2022, as a
one of 10 piggyback 6U satellites onboard the NASA Artemis 1 SLS, and
successfully detached from the SLS rocket. After the checkout operation
and first light imaging, the camera successfully took images of the far
side of the moon during the lunar flyby, and comet ZTF (C/2022 E3) etc.
In this talk, I'll also present ground-based observations of the lunar
impact flashes in Japan and laboratory experiments of hyper-velocity
impact flash, ~7kms, using JAXA's 2-stage light gas gun.
