Hayabusa2 second touchdown on asteroid Ryugu


JAXA — Hayabusa2 Mission patch.


July 27, 2019


On July 11, the Hayabusa2 spacecraft performed a 2nd touchdown on the surface of asteroid Ryugu. The touchdown occurred at 10:06 JST at the onboard time and was successful. Below we show images taken before and after the touchdown. As this is a quick bulletin, more detailed information will be given in the future.



Hayabusa2’s second touchdown on asteroid Ryugu

Video above:JAXA’s Asteroid Explorer “Hayabusa2” performed a second touchdown to collect a sample from asteroid Ryugu on 11 July 2019. The video was created from images captured with Hayabusa2’s CAM-H at intervals between 0.5s and 5s and played back at 10x speed.
The first image was taken at an altitude of about 8.5m and the last is from an altitude of about 150m. Video Credits: JAXA, University of Tokyo, Kochi University, Rikkyo University, Nagoya University, Chiba Institute of Technology, Meiji University, Aizu University, AIST/SciNews.


Images taken with the Optical Navigation Camera – Wide angle (ONC-W1)


Immediately after touchdown, we captured images with the ONC-W1. Here are two bulletin images from this camera.

Images from the Small Monitor Camera (CAM-H)


CAM-H operated before and after touchdown, capturing images 4 seconds before touchdown, the moment of touchdown and 4 seconds after touchdown. (CAM-H is the camera that was developed and installed on Hayabusa2 through public donations. The field of view is downwards beside the sampler horn.)
