WebNASA’s heliophysics researches the ionosphere-thermosphere-mesosphere region where our neutral atmosphere transitions into the ionized plasma of space. In this thin shell that surrounds our home planet, the atmosphere is in constant motion, shaped by the influence of both solar activity and changes in the lower atmosphere and in near-Earth space. WebExosphere: The exosphere is the outermost layer of the atmosphere which accounts for lesser than 1 % of the total mass of the atmosphere. Some scientists consider the …
