国外木星探测任务进展与分析

Progress and Analysis of Foreign Jovian Exploration Missions

为了更好地规划我国木星探测任务,文章对国外木星探测任务的发展状况进行了调研分析。对比分析了伽利略号、朱诺号、木星冰月探测者和欧罗巴快帆任务的探测目标,并对上述任务采用的运载火箭、探测轨道与通信系统进行了分析总结。指出未来木星探测任务所需运载火箭地球同步轨道转移能力应在10t以上,以对木卫展开全面覆盖探测,采用Ka频段作为下行数据载波。在上述分析的基础上,提出了我国木星探测的任务目标和初步规划的建议。

In order to make a better plan for China’s Jovian exploration mission,this paper investigates the development status of foreign Jovian exploration missions.This paper compares the detection targets of Galileo,Juno,JUpiter ICy moons Explorer(JUICE)and Europa Clipper mission,and summarizes the launch vehicles,exploration orbits and communication systems used in these missions.It is pointed out that the GTO capability of the launch vehicles required for the future Jupiter missions is above 10t,and the objectives are the global-regional coverage exploration of Jovian satellites,using Ka band as downlink carrier.On the basis of the above analysis,the mission objectives and preliminary planning of Jovian exploration in China are proposed.
