Dust Measurements with the DESTINY+ Mission to the Active Asteroid (3200) Phaethon — •Harald Krüger1,2, Masanori Kobayashi2, Ralf Srama3, Tomoko Arai2, and DESTINY Dust Science Team1,2,3 — 1MPI für Sonnensystemforschung, Göttingen, Germany — 2PERC, Chiba Institute of Technology, Narashino, Japan — 3Institut für Raumfahrtsysteme, Universität Stuttgart, Germany
The DESTINY+ spacecraft will be launched by the Japanese Space Agency JAXA in 2028. The main mission target will be the active asteroid (3200) Phaethon, with a close flyby in 2030. Together with two cameras on board, the DESTINY+ Dust Analyzer (DDA) will perform in-situ measurements at Phaethon to solve essential questions related to the evolution of the inner Solar System, including heating processes and compositional evolution of small solar system objects. Phaethon is believed to be the parent body of the Geminids meteor shower and may be a comet-asteroid transition object. Such objects can likely provide information to better understand the nature and origin of mass accreted onto Earth. DDA is an upgrade of the Cassini Cosmic Dust Analyzer (CDA) which very successfully investigated the dust environment of the Saturnian system. DDA is an impact ionization time-of-flight mass spectrometer with integrated trajectory sensor, which will analyse sub-micrometer and micrometer sized dust particles. We give an overview of the DESTINY+ mission, the Dust Analyzer DDA and the science goals for the analysis of Phaethon dust, as well as interplanetary and interstellar dust to be measured en route to Phaethon.
