火星大气和挥发性演化观测显示了冲击太阳风与扩展的氧气大气和热日冕相互作用的清晰特征，这些特征显示在磁鞘流的横向偏转中，方向与太阳风运动电场的方向相反。速度偏转值达到∼50 km/s。这种偏转的发生是由“洛伦兹型”力引起的，该力是由于太阳风质子和源自扩展氧日冕的氧离子的差异流而引起的。由于质量载荷造成的磁鞘流的总减速度估计为~40 km/s。
Mars Atmosphere and Volatile EvolutioN observations at Mars show clear signatures of the shocked solar wind interaction with the extended oxygen atmosphere and hot corona displayed in a lateral deflection of the magnetosheath flow in the direction opposite to the direction of the solar wind motional electric field. The value of the velocity deflection reaches ∼50 km/s. The occurrence of such deflection is caused by the “Lorentz‐type” force due to a differential streaming of the solar wind protons and oxygen ions originating from the extended oxygen corona. The value of the total deceleration of the magnetosheath flow due to mass loading is estimated as ∼40 km/s.
