DESTINY+ mission aims to perform fast flyby observation of an active asteroid, 3200 Phaethon, dust observation during the interplanetary cruising and Phaethon flyby phases. DESTINY+ Dust Analyzer (DDA) for the dust observation is the successor to the Cosmic Dust Analyser (CDA) onboard the Cassini spaceprobe, using impact ionization time-of-flight mass spectrometry. The develpment of DDA has been led by University of Stuttgart, Germany, while the interface adjustment between the spacecraft and DDA, the ground calibration, and so on are conducted in coordination between Japanese and German research team. In this presentation, the latest instrument design reflected the restriction of mass resource and the strategy of ground calibration utilizing secondary ion mass spectrometry (SIMS) will be reported.
