Noctilucent clouds on Mars

This paper discusses a model for the genesis and climatology of noctilucent clouds in the atmosphere of Mars, based on the analogy of the latitude-sea sonal temperature and humidity distribution of the mesopauses of Mars and t he earth. The representation of noctilucent clouds as the tracks of the sno wy cores of minicomets is regarded as a confirmation of the hypothesis of t he possibility of the presence of water and the existence of life on other planets of the universe.
