TopicsRyugu rotation movie

A selection of the images captured by the Optical Navigation Cameras (ONC) have been released on the open space science data archive, DARTS (Data ARchives and Transmission System). The DARTS archive is maintained by the Center for Science-satellite Operation and Data Archive (C-SODA) at ISAS, JAXA. Using this publicly available data, we have created a movie.

Figure 1 shows Ryugu’s north pole facing towards the top of the image in the usual orientation. The large Otohime boulder can be seen near the bottom. In Figure 2, Ryugu is shown in the orientation used when the Earth is pictured in the Solar System, with the direction of the Earth’s north pole facing up. In this case, Ryugu’s south pole faces the top of the image as Ryugu rotates in the opposite direction to the Earth (retrograde rotation).
