针对近年来月球与火星探测成为各航天大国的热点,以及中国首个火星探测计划“萤火1号”拟定的科学研究目标,文章对火星重力场模型的历史、现状及展望做了简要描述.文中首先探讨了火星探测的多重意义和火星重力场往火星探测中起到的重要作用;接着介绍了火星重力场模型发展的历史和现状;最后介绍了利用中国“萤火1号”轨道跟踪数据对火星重力场模型的可能贡献,在此基础上对中国未来火星重力场探测提出了设想.
Exploration of the Moon and Mars has been a focal point for several countries. The development of China's first Mars mission Yinghuo-1, and the history, status and prospects of the Martian gravity field model are briefly reviewed. First, the multiple significance of exploring Mars and the role of the Martian gravity field model in this exploration are discussed, followed by a detailed description of the model. Finally, the potential contribution of the orbital tracking data of Yingbuo-1 to this model is discussed, based on which suggestions for China's future Martian gravity detection program are given.
