The plasma interactions of the different bodies in the solar system differ, but some processes are key at many of them. The main controlling factors are (1) upstream plasma conditions (including Mach number, dynamic pressure) and (2) the nature of the object (including magnetic field, presence of an atmosphere/exosphere, presence of internal sources and plasma discs, ion pickup processes). The processes involve magnetic reconnection, shocks and ion pickup. In this project the solar wind interaction with Mars will be studied using 17 years of data from ASPERA-3 to search for effects associates with surface features and dust storms. The results will be relevant for the Rosalind Franklin PanCam instrument and its operations.

太阳系中不同天体的等离子体相互作用各不相同，但其中一些过程是关键。主要控制因素是（1）上游等离子体条件（包括马赫数、动压）和（2）物体的性质（包括磁场、大气层/外逸层的存在、内部源和等离子体盘的存在、离子拾取过程）。这些过程包括磁场重联、冲击和离子拾取。在该项目中，将利用ASPERA-3号卫星17年的数据研究太阳风与火星的相互作用，以寻找与表面特征和沙尘暴有关的影响。结果将与Rosalind富兰克林PanCam仪器及其操作相关。
