The article posted on July 25, 2018 introduced an image captured when Hayabusa2 descended towards asteroid Ryugu, reaching an altitude of just 6km above the surface. At this time, we also took photographs in which the viewing angle towards the asteroid gradually changed as Ryugu rotated. Using the previously published image and a second image from a slightly different angle (see the referlence at the end of this page), we created a composite frame where the two photographs are superimposed in red and blue. If you view this image with red-blue stereoscopic glasses (right eye should be blue, left eye is red), you can see this high resolution image of the asteroid in three-dimensions and explore the shape and topography of this small world.
Comparing this new image with the stereoscopic image we previously introduced (part 1, part 2), the three-dimensional view is much more powerful with the irregularities on the surface significantly more emphasized. This is due to the high resolution of the composite photographs which were taken closer to the asteroid, and because the difference in the angle at which each image sees the asteroid is larger than that difference would be between the view from your left and right eye. While it depends on exactly how each person sees the stereo image, do be careful that the features may be exaggerated compared to the actual shape of Ryugu and the contours of the terrain.
Different types of topography can be spotted, such as the overhang along the equator of Ryugu in the center of the image and the unevenness created by the variety of large and small boulders as well as the circular dents of craters.
