    "abstract": "The Mesosphere is interested by important chemical and dynamical phenomena,\nso observation of its Sodium layer\u0027s behavior has became a common target of\nseveral research plans all over the world. In order to study its dynamical and\nchemical variation during daytime (so the solar flux, which is not localized,\nstimulates the Sodium emission) we want to observe from the space continuously\nthe Sodium emission (and perform differential analysis looking for periodic\nchanges), using a small telescope with a Magneto-Optical Filter and a image\nsensor.",
