AB: Solar wind induced escape is one of the effective mechanisms responsible for atmospheric and ionospheric losses on Mars. ASPERA-3 observations carried out on the MEX spacecraft reveal the efficient extraction and energization of planetary ions. Planetary ions (O+, O2+, CO2+) gain energy of several keV on distances of several thousands km from the planet. It is found that processes of ion extraction and penetration of solar wind plasma into the Martian magnetosphere are closely related. Morphology of ion fluxes, role of crustal fields and mechanisms of extractions are discussed.
