  The Martian Moons Exploration (MMX) spacecraft is a JAXA mission to Mars and
its moons Phobos and Deimos. MMX will carry the Circum-Martian Dust Monitor
(CMDM) which is a newly developed light-weight ($\mathrm{650\,g}$) large area
($\mathrm{1\,m^2}$) dust impact detector. Cometary meteoroid streams (also
referred to as trails) exist along the orbits of comets, forming fine
structures of the interplanetary dust cloud. The streams consist predominantly
of the largest cometary particles (with sizes of approximately
$\mathrm{100\,\mu m}$ to 1~cm) which are ejected at low speeds and remain very
close to the comet orbit for several revolutions around the Sun. The
Interplanetary Meteoroid Environment for eXploration (IMEX) dust streams in
space model is a new and recently published universal model for cometary
meteoroid streams in the inner Solar System. We use IMEX to study the detection
conditions of cometary dust stream particles with CMDM during the MMX mission
in the time period 2024 to 2028. The model predicts traverses of 12 cometary
meteoroid streams with fluxes of $\mathrm{100\,\mu m}$ and bigger particles of
at least $\mathrm{10^{-3}\,m^{-2}\,day^{-1}}$ during a total time period of
approximately 90~days. The highest flux of $\mathrm{0.15\,m^{-2}\,day^{-1}}$ is
predicted for comet 114P/Wiseman-Skiff in October 2026. With its large
detection area and high sensitivity CMDM will be able to detect cometary
meteoroid streams en route to Phobos. Our simulation results for the Mars
orbital phase of MMX also predict the occurrence of meteor showers in the
Martian atmosphere which may be observable from the Martian surface with
cameras on board landers or rovers. Finally, the IMEX model can be used to
study the impact hazards imposed by meteoroid impacts on to large-area
spacecraft structures that will be particularly necessary for crewed deep space
missions.
