Interstellar dust predictions for the Destiny+ mission

Destiny+ is a Japanese-German space mission to be launched in 2028, first flying by the near Earth Asteroid Apophis in 2029 after which it will continue on its route to the active asteroid Phaeton for a flyby in 2030. The period around 2029-2030 is in the phase of the solar cycle in which small interstellar dust and cometary dust is focused near the ecliptic plane. This presents unique and ideal conditions for in situ measurements of interstellar dust in the solar system, close to the Earth. We present predictions for the interstellar dust flux and flow direction that Desiny+ will be able to measure for different assumed material properties. We use two prediction methods of which one is designed to take into account the filtering in the heliosheath using previous in situ measurements.
