This photo was taken on Ryugu’s surface by the MINERVA Rover-1A during a successful hop on Sept. 22. The left-half is the rocky surface of Ryugu, while the white region at right is due to sunlight reflecting in the camera’s optics. The MINERVA rovers are the first to land on the surface of an asteroid. JAXA
I had to share this first incredible photo taken by one of the MINERVA robots we talked about in Friday’s blog. Both of the MINERVAs landed successfully on the surface of the asteroid Ryugu, and this image was taken the very next day (Sept. 22).
