Scientific priorities of Mars exploration: what’s done? • Climate dynamics (atmospheric temperature, water, dust, clouds) • Surface and subsurface volatiles inventory • Paleoclimate records in surface composition and morphology • Extra rare constituents (methane)
Future plans • NASA: Mars Science Laboratory (rover), MAVEN (atmosphere sample analysis). Soil sample return mission in a foreseeable perspective. • ESA: ExoMars – rover with drilling capabilities.
What’s to be done by orbiters • Wide-field hyperspectral monitoring (analog of VEX/VIRTIS) • High resolution spectroscopy in IR and/or microwave ranges for isotopic analysis and Doppler measurements (present in NASA and ESA programs)
What’s to be done by landers • Mars internal structure and composition - a network of seismometers • Meteo network • Surface thermal & electric conductivity – penetrating probes (depth 10-20 cm )

Resume • A network mission to Mars with small stations bearing meteo package, seismic sensors and optional instruments may get a high priority for the Russian national space program. • Rich technical heritage and connection with European and US groups involved in similar network missions leaves a hope that it will be implemented shortly
