|Confirmation of landing candidate sites from the rehearsal operation|
From September 10 to 12, we conducted the Touchdown 1 Rehearsal 1 (TD1-R1) operation and were able to confirm the selection of the candidate sites for touchdown. Figure 1 shows an image taken from about 3km above the asteroid surface using the Optical Navigation Camera – Telescopic (ONC-T).
Figure 1: Image of the touchdown candidate sites taken from about 3km above the surface using the Optical Navigation Camera – Telescopic (ONC-T). The image was captured on September 12, 2018 at around 06:00 JST. In the right-hand image, the approximate areas of the touchdown candidate sites are marked out.

In the right-hand image of Figure 1, the areas for the touchdown candidate sites are marked out. L08 is the primary touchdown candidate site, while L07 and M04 are the back-up choices. Part of L07 extends slightly beyond the image, but most of that area is captured.
Touchdown operations will continue to be studied from now on.
