论文摘要

ESA-JAXA BEPICOLOMBO任务将提供两种航天器的同时测量，提供前所未有的机会，以研究汞处的磁层和外层动力学以及它们与太阳风，辐射，辐射，散热尘的相互作用。这两个航天器上的许多科学仪器将完全或部分致力于研究汞的近距离环境以及控制汞的复杂过程。即使在2015年结束的使者任务结束后，许多问题仍然无法解决。与单独行动或以前的任务相比，这两个航天器的特定轨道，MPO和MIO的特定轨道和全面的科学有效载荷可以解决更多的科学问题。这些联合观察至关重要，因为水星环境中的许多现象在时间上是高度的和空间上的。本文中描述了可能的协调观察的示例，分析了不同Bepicolombo仪器传感器所需的几何条件，指向，决议和操作时间。

The ESA-JAXA BepiColombo mission will provide simultaneous measurements from two spacecraft, offering an unprecedented opportunity to investigate magnetospheric and exospheric dynamics at Mercury as well as their interactions with the solar wind, radiation, and interplanetary dust. Many scientific instruments onboard the two spacecraft will be completely, or partially devoted to study the near-space environment of Mercury as well as the complex processes that govern it. Many issues remain unsolved even after the MESSENGER mission that ended in 2015. The specific orbits of the two spacecraft, MPO and Mio, and the comprehensive scientific payload allow a wider range of scientific questions to be addressed than those that could be achieved by the individual instruments acting alone, or by previous missions. These joint observations are of key importance because many phenomena in Mercury's environment are highly temporally and spatially variable. Examples of possible coordinated observations are described in this article, analysing the required geometrical conditions, pointing, resolutions and operation timing of different BepiColombo instruments sensors.
