The shape at this point reminds me more of Balok's warning buoy...

Amazing, the diversity that we see in small bodies.

This is what granular NaCl (table salt) looks like under a microscope.

We're now less than 100 km from the asteroid, and the asteroid's size should be about 100 pixels in Hayabusa 2's camera.

The approach speed has slowed a lot to 0.28ms, which of course is sensible.

I had an interesting experience today. As usual, I accessed the main web page of Hayabusa 2 and the speed was
something like 53m/s, very slow as somebody remarked, at walking pace, and then I doubted my vision.

The number in the speed of 53m/s seemed to have changed in a very short while my eyes were off the display
unit. I was not sure if the number that I was seeing was the number that I had seen, so I kept watching and
within a few seconds I realised that the number was indeed changing in front of my eye balls.

In fact, the speed kept going down over the next 30 or 40 seconds. It kept going down, and down, until it
reached 28m/s and it is staying there.

This episode was around PM12:38 or 12:39 local JST today (20 June 2018).

My current hope is that since the home height is 20km, and the remaining distance shown is as far as to that
home position we may start seeing something on the Haya2 control panell display window for OCN-W1 at around
30,40km height, no?

There is also something else I now understand about the speed. The speed shown on the main web page is the
absolute value of the vector quantity and the actual speed of approaching Ryugu is the projetion, hence
can be slower (usually).

At this rate of going, though, we may be having a clear view of Ryugu within the next 24 hours?
