Ryugu as seen by Hayabusa-2 from less than 4 miles
The image on the right as a cropped section of an image taken by Hayabusa-2 from only 3.7 miles distance from the asteroid Ryugu. If you click on the link you can see the full image. I picked this section to crop out because it shows the asteroid’s limb, an interesting boulder field, and part of a the asteroid’s largest crater, on the lower right. As noted by the Hayabusa-2 science team in describing details in the full image:
The resolution in Figure 1 is about 3.4 times higher than the images taken from the Home Position [20 kilometers distance] so far. 1 pixel in Figure 1 corresponds to about 60cm. The largest crater on the surface of Ryugu is situated near the center of the image and you can see that it has a shape like a “mortar”. You can also see that the surface of Ryugu is covered with a large number of boulders. This picture will provide important information as we choose the landing site.
The smallest objects visible are thus about two feet across.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

Looking at this picture I want to share an observation that I have made here before and would be interested in anyone’s comment on the subject. Its a bit existential.
From my point of view, the universe at its purest state is pure energy, and what we are looking at here in this picture, and in fact what we exist living in and on and are made of is the detritus from the result of that transformative event.
We exist like insects live in the detritus of the result of the big bang. Which leaves the remaining question: What is all this really about?
