This animation shows how the spacecraft tracked the target marker during touchdown on Feb 22. The bright white dot is the target marker on Ryugu’s surface. From the movement of Hayabusa2’s shadow, you can see how the target marker is tracked. Animation:

This image was captured with our wide-angle Optical Navigation Camera (ONC-W1) during touchdown on February 22 and made into a short animation released today (March 20). You can see how the surface of Ryugu changes immediately after touchdown! Animation:

★ Hayabusa2 status (2019.3.4) ★ This week, we conducted the “Descent Observation” operation (DO-S01) from 3/6 to 3/8 in order to observe a future touchdown candidate site (S01) in detail. (Full text in image and can also be found online here: )

Last week Hayabusa2 descended to observed the S01 area near the Kolobok Crater [DO-S01]. This image sequence was captured by the wide-angle ONC-W1 during the descent, down to an altitude of 22m. Where should we touchdown after “Tamatebako” (nickname for our TD point)?

★ Hayabusa2 status (2019.2.25) ★ Immediately after returning to the “home position” at a 20km altitude after the TD1-L08E operation on 2/23, we began a BOX-C operation in which the spacecraft descends to an altitude of about 5km... Full report in the attached image!

[DO-S01] This is the navigation image on 3/8 at ~12:04 JST. Ryugu now fills the field of view! On the navigation image site, the images are brightening due to the opposition effect, so we adjusted the brightness correction setting for the ground processing
