Abstract Hayabusa2 arrived at the C-type asteroid Ryugu in June 2018. During one and a half year of the Ryugu-proximity operation, we succeeded in two rovers landing, one lander landing, two spacecraft touchdown/sample collection, one kinetic impact operation and two tiny reflective balls and one rover orbiting. Among the two successful touchdowns, the second one succeeded in collecting subsurface material exposed by the kinetic impact operation. This paper describes the asteroid proximity operation activity of the Hayabusa2 mission, and gives an overview of the achievements done so far. Some important engineering and scientific activities, which have been done in synchronous with the spacecraft operations to tackle with unexpected Ryugu environment, are also described.

Hayabusa2 任务状态:在小行星 Ryugu 上着陆、漫游和撞击

摘要 隼鸟二号于 2018 年 6 月抵达 C 型小行星龙宫。在龙宫接近运行的一年半时间里,我们成功完成了两次漫游车着陆、一次着陆器着陆、两次航天器着陆/样本采集、一次动能撞击操作和两个微小的反射球和一个绕轨道运行的漫游车。在两次成功的着陆中,第二次成功地收集了动力冲击作业暴露的地下物质。本文描述了隼鸟2号任务的小行星接近操作活动,并概述了迄今为止取得的成就。还描述了一些与航天器运行同步进行的重要工程和科学活动,以应对意外的 Ryugu 环境。
