The objective of the Electron Losses and Fields INvestigation on board the Lomonosov satellite (ELFIN-L) project is to determine the energy spectrum of precipitating energetic electrons and ions and, together with other polar-orbiting and equatorial missions, to better understand the mechanisms responsible for scattering these particles into the atmosphere. This mission will provide detailed measurements of the radiation environment at low altitudes. The 400–500 km sun-synchronous orbit of Lomonosov is ideal for observing electrons and ions precipitating into the atmosphere. This mission provides a unique opportunity to test the instruments. Similar suite of instruments will be flown in the future NSF- and NASA-supported spinning CubeSat ELFIN satellites which will augment current measurements by providing detailed information on pitch-angle distributions of precipitating and trapped particles.

罗蒙诺索夫卫星上电子损耗和场调查的科学目标

罗蒙诺索夫卫星 (ELFIN-L) 项目上的电子损耗和场调查的目标是确定高能电子和离子沉淀的能谱，并与其他极地轨道和赤道任务一起，更好地了解负责的机制将这些粒子散射到大气中。该任务将提供低空辐射环境的详细测量结果。罗蒙诺索夫 400-500 公里的太阳同步轨道非常适合观察沉淀到大气中的电子和离子。该任务提供了测试仪器的独特机会。
