Interplanetary trajectory of MMX (thick red line). Blue diamonds indicate the crossings of cometary trails with predicted dust fluxes of at least \(10^{-3}\,\mathrm {m}^{-2}\,\mathrm {day}^{-1}\) (cf. Fig. 1). Blue lines indicate the approach direction (speed vector) of trail particles onto the spacecraft in the spacecraft-centered reference frame projected onto the X-Y plane (cf. Table 1). The X-Y plane is the ecliptic plane with vernal equinox oriented towards the +X direction. The comet orbits are superimposed as thin lines
