We present a summary of the campaign of remote observations that supported the European Space Agency's Rosetta mission. Telescopes across the globe (and in space) followed comet 67P/Churyumov-Gerasimenko from before Rosetta's arrival until nearly the end of the mission in September 2016. These provided essential data for mission planning, large-scale context information for the coma and tails beyond the spacecraft and a way to directly compare 67P with other comets. The observations revealed 67P to be a relatively 'well-behaved' comet, typical of Jupiter family comets and with activity patterns that repeat from orbit to orbit. Comparison between this large collection of telescopic observations and the results from Rosetta will allow us to better understand comet coma chemistry and structure. This work is just beginning as the mission ends-in this paper, we present a summary of the ground-based observations and early results, and point to many questions that will be addressed in future studies.This article is part of the themed issue 'Cometary science after Rosetta'.
我们总结了一系列支持欧洲航天局罗塞塔任务的远程观测活动。全球各地(以及太空中)的望远镜从罗塞塔号抵达之前一直跟踪67P/丘留莫夫-格拉西缅科彗星,直至2016年9月该任务接近尾声。这些观测为任务规划提供了关键数据,为飞船之外的彗发和彗尾提供了大规模背景信息,还提供了一种将67P与其他彗星直接比较的方法。观测结果显示,67P是一颗相对“表现良好”的彗星,属于木星族彗星,其活动模式在不同轨道间重复出现。将这大量的望远镜观测数据与罗塞塔号的探测结果进行比较,将有助于我们更好地理解彗星彗发的化学组成和结构。随着任务结束,这项工作才刚刚开始——在本文中,我们总结了地面观测情况和早期结果,并指出了许多将在未来研究中探讨的问题。本文是主题为“罗塞塔号之后的彗星科学”特刊的一部分。
