Other AbstractMars dust contributes to the Mars atmosphere dynamic and thermodynamic evolution process and the long-term modification of Mars albedo and surface geology.Mars dust environment is very crucial for the power system and optical sensors onboard Mars landers (or rovers).There is a need for Mars dust in situ measurement.The characteristics and main detecting solutions of Mars dust were discussed.Based upon Quartz Crystal Microbalance technology, the design of Mars dust characteristic integrated detecting system (MDCIDS) was proposed.MDCIDS includes 3 kinds of sensors.The dust accumulation sensor can measure the accumulation rate and mass of Mars dust with sensing crystal surface upward.The charging dust sensors can measure the accumulation rate of positive and negative charging dust through applying different bias voltages to crystals.And the magnetic dust sensors can measure the accumulation rate of magnetic dust with small permanent magnets behind sensing crystals.The accumulation mass range is 10~(-11)~10~(-4)g.MDCIDS is expected to be applied to future Mars landing exploration mission.
