The transport of plasma and magnetic field through the magnetosphere of Mars will be investigated by a three-dimensional hybrid code simulation. It is intended to tie in with the observations of the Phobos-2 and Mars Global Surveyor missions and to model the global three-dimensional plasma and magnetic field structures near Mars. Particularly, the plasma boundaries will be studied and their physical nature will be examined on a microscopic-kinetic basis of the hybrid description. The understanding of the transport/non-transport of mass, momentum, and energy through the magnetic pileup boundary plays the key role. The plasma transport is immediately associated with the evacuation of the atmosphere and the dehydration of Mars. Escape and loss rates will be simulated for the present situation of Mars and also for expected prehistoric conditions where Mars could have had a much denser atmosphere and an internal planetary magnetic field. The goal of the project is to clarify open questions about the plasma and magnetic field structures near Mars, and to derive a quantitative model for the water balance on Mars.

利用三维混合代码模拟研究了等离子体和磁场在火星磁层中的输运。它的目的是结合火卫一2号和火星全球勘测者任务的观测，并模拟火星附近的全球三维等离子体和磁场结构。特别是，等离子体边界将被研究，其物理性质将在混合描述的微观动力学基础上进行检验。通过磁堆积边界的质量、动量和能量的输运/非输运的理解起着关键作用。等离子体的传输与火星大气的疏散和脱水直接相关。逃逸和损失率将模拟火星目前的情况，也将模拟火星可能有更稠密的大气层和内部行星磁场的史前条件。该项目的目标是澄清关于火星附近等离子体和磁场结构的悬而未决的问题，并推导出火星上水平衡的定量模型。
