In laboratory of space instrument making of the Samara state aerospace university is developed and made equipment "Chistota" for the control of parame-ters of external atmosphere SC "Photon-M" #2. Flight SC "Photon-M" #2 took place in June 2005. Module "Dust" is intended for data gathering about characteristics of dust particles in vicinity SC. For the given purpose two gauges, established on surface SC were used. Gauges were combined and made measurement of temperature of a surface of the gauge, fixed presence of a sunlight, registered flying by dust parti-cles in the optical way, measured weight of the adsorbed substance on a surface of the quartz resonator. The received experimental data have shown, that temperature gauges have appeared disabled, gauges of a flare, quartz and optical gauges have carried out the problem. Now processing of the received results is made, but it is already possible to tell, that data you-look it is interesting enough: approximately on 3 business hour it is observed decrease the settled weight on quartz gauges, and optical gauges give enough greater concentration of dust particles. Processing of results will be completed in the summer 2006.
