Abstract
Hayabusa2 is an asteroid sample return mission carried out by the Japan AerospaceExploration Agency. The spacecraft was launched in 2014 and arrived at the target asteroidRyugu on June 27, 2018. During the 1.5-year proximity phase, several critical operations(including two landing/sampling operations) were successfully performed. They were basedon autonomous image-based descent and landing techniques. This paper describes an image-based autonomous navigation scheme of the Hayabusa2 mission using artificial landmarksnamed target markers (TMs). Its basic algorithm, and the in-flight results of the firsttouchdown and its rehearsal, are shown.
