It was suggested first by Soter [1] that dust rings exist around Mars, formed by particles released from Phobos and Deimos. The configuration of such rings has been studied theoretically (see [2] and references therein) but so far, attempts to detect the rings remotely were unsuccessful [3]. A promising opportunity to detect and characterize these rings are the measurements to be performed with the Circum Martian Dust Monitor (CMDM) instrument [4] on the JAXA mission Mars Moons Explorer (MMX) [5]. In this paper we employ recent results from computer simulations [2] of the Martian dust rings to evaluate the dust fluxes expected for CMDM along the orbital tour of MMX around Mars.
