The JAXA/ISAS spacecraft DESTINY$^+$ will be launched to the active asteroid
(3200) Phaethon in 2022. Among the proposed core payload is the DESTINY+ Dust
Analyzer (DDA) which is an upgrade of the Cosmic Dust Analyzer flown on the
Cassini spacecraft to Saturn (Srama et al. 2011). We use two up-to-date
computer models, the ESA Interplanetary Meteoroid Engineering Model (IMEM,
Dikarev et al. 2005), and the interstellar dust module of the Interplanetary
Meteoroid environment for EXploration model (IMEX; Sterken2013 et al., Strub et
al. 2019) to study the detection conditions and fluences of interplanetary and
interstellar dust with DDA. Our results show that a statistically significant
number of interplanetary and interstellar dust particles will be detectable
with DDA during the 4-years interplanetary cruise of DESTINY+. The particle
impact direction and speed can be used to descriminate between interstellar and
interplanetary particles and likely also to distinguish between cometary and
asteroidal particles.
