I'll wager there'll be time to go and find those 3-d specs (or even make a pair) before this ani-gif of a rotating Ryugu finishes loading...

Having descended from its 20km "home position", Hyabusa2 took this image from 6km above Ryugu.

The aggregate/conglomerate complexity is amazing. I wish there was a grid scale version. Impressive stuff.

That shallow depression - did the impactor end up below the surface?

The pixel resolution is 60 cm - an image processor (i.e. not me) could build grid overlays? :ask:

For the next phase of the mission JAXA has built a new website with loads of pages, some still in preparation, and other information. One's language choice on the home page doesn't necessarily follow through the rest of the site though... Still, it's a :thumbup: from me.

A view from 1km above Ryugu taken on August 7th before returning to "home position". This round trip was designed to measure local gravity and prepare for the landing ahead...

Hayabusa2 prepares to collect samples, leave Planetary Society names on Ryugu

Japan’s Hayabusa2 spacecraft, which has already returned some initial science from asteroid Ryugu, will soon try to collect a sample from the surface. Touchdown rehearsals are planned in September and October, with the first attempt expected in late October.

The original plan was for Hayabusa2 to collect multiple samples from several locations, to gather a broad range of materials. But it turns out Ryugu’s surface is fairly diverse to begin with, and since sampling is a risky procedure, the team is now focusing on a single location near the equator.
...

The vertical velocity is measured with laser ranging. But to determine its horizontal velocity, Hayabusa2 needs to watch a fixed point on the surface. That's what the target markers are for. The target markers look like baseballs covered with gridded, reflective cloths, and they have little rods poking out. Like bean bags, they are filled with grainy particles, so that when Hayabusa2 drops one onto the surface, it won’t bounce.

Reports are that last night's descent and release of 2 Minerva II rovers was successful and the rovers appear to have landed and snapped their first images but that data is not yet confirmed.

The navigation images to deployment are posted here: http://www.hayabusa2.jaxa.jp/en/galleri ... v20180920/

The shadow of Hyabusa-2 cast on Ryugu below is visible on a couple of shots. :thumbup:

Hyabusa2@jaxa:
[MINERVA-II1] Communication with MINERVA-II1 has currently stopped. This is probably due to the rotation to Ryugu, and MINERVA-II1 is now on the far side of the asteroid. We are currently working to confirm if there are images capturing the MINERVA-II1 landing.


Suspenseful!

All is well. Phew!
On September 21, the small compact MINERVA-II1 rovers separated from the Hayabusa2 spacecraft (time of separation was 13:06 JST). The MINERVA-II1 consists of two rovers, Rover-1A and Rover-1B. We have confirmed both rovers landed on the surface of asteroid Ryugu. The two rovers are in good condition and are transmitting images and data. Analysis of this information confirmed that at least one of the rovers is moving on the asteroid surface.

I wonder if Hayabusa is a name, or a word that means something else, like “goes like a motherfucker”.

That asteroid has a lot of metal in it. Some people look at a nearby asteroid and immediately start thinking about mining operations. If they dug away 50% of it, would it then be a half-asteroid?
