TOKYO (JAXA PR) — During the second touchdown rehearsal (TD1-R1-A), we captured a sequential set of images as the spacecraft reached the point of lowest altitude and then began to rise. The spacecraft reached the lowest altitude of 22.3m above the surface of Ryugu on October 15, 2018 at 22:44 JST. [Editor’s Note: Hayabusa2 has completed three landing rehearsals.]
The most promising candidate site for touchdown is L08-B and is also captured in these images (Figure 2). As you can see in Figure 2 and Figure 1, there are not any large boulders in L08-B, but there is a big cliff-like boulder in the upper right of Figure 2 so care is still needed.
In the future, these images obtained during the rehearsals will be analyzed in more detail to aim for a safe touchdown.
If you enlarge the shadow of the probe shown in Figure 2, you will see the following figure. The gap between the panels of the solar paddle is easily visible, as is the shape of the spacecraft and the two star trackers.
