Excellent work! Do you have a cylindrical projection as well?

Today's JAXA press conference on the current status of Hayabusa 2: http://www.youtube.com/watch?v=HX2TBQV1yyE

Video description reads: "The asteroid explorer "Hayabusa 2" is currently checking the functions of various equipment after arrival while maintaining the position about 20 km from the asteroid Ryugu (Ryugu). In this briefing session, we will explain the current situation of "Hayabusa 2", if observation data of Ryugu has been obtained, we will explain it."

Anyone here knowlegeable in Japanese could please provide the main points and captions to the images? Here's the pdf with the slides: http://fanfun.jaxa.jp/jaxatv/files/20180719_hayabusa2.pdf

Couple of interesting ones:

Attached Image

Longitude zero degree point of Ryugu.
Point selected as longitude zero degree.
Reason for selection:
· Good visibility
· The center is easy to ask
· Undulations are conspicuous
· Close to the equator

Attached Image

Mt Fuji and Ryugu from 20 km away.

I hope they'll provide an English version of this pdf.

Here are my translaions up to page 13. I may translate some more as JAXA seem to be releasing newer(?)
explanations.

P6: H2 is now descending from HP, i.e., from BOX-A to BOX-C

P8: Ryugu begins to show features

1. very dark and spin axis is perpendicular to orbital plane

2. craters, many blocks of rock, as large as 130m diam., trench like feature

P10: Shape models by two different groups with SfM and SPC methods

P11: Longtitude zero point selection and reasons

1. project members noticed, earlier on, as a prominent point with two rocks above and below, good for a landmark

2. these two rokcd are close to the equator and can serve as a landmark

NB: Here, north pole is up and south pole is down

P12: Mt. Fuji and Ryugu as seen from a distance of 20km away (movie)

P13: Rock distribution, left pic at 300 degrees, right pic at 60 degrees

1. fairly large rocks are seen for such a small astronomical body, possibly fractures of mother bodies re-assembled

2. number density of rocks varies greatly from one place to another

3. touch down location dependent on rock number density

4. helpful in understanding of surface materials migration

Translation continues. Prof Yoshikawa said in the video that H2 is, as at the time of press briefing, at 13km height,
trying to go down to 6km height very shortly. All this is actually on the few pages from page 29, hence this
translation.

P29: Mission schedule as follows.

1. Regular observation is from HP, and that is BOX-A. at height of 20km.

2. Lowering of H2 is as follows.

2.1 BOX-C operation: 17 o 23 July, reaching minimum height of 6km between 20 and 22 July

2.2 Further lowering to middle height between 1 and 2 August, reaching minimum height of 5km on 1 August

2.3 Gravity measurement descent between 6 and 7 August, reaching minimum height of 1km on 7 August

3. H2 touring operation with BOX-B, taking place end August.

P30: BOX operations

1. Regular observation is BOX-A, at 20km height

2. BOX-B operation is meant for touring, hovering also horizontally for observation from different angles.
Horizontal displacement is +/- 20km and in R-Earth Z direction, +/- 10km from HP

3. BOX-C operation is meant for hovering elongated vertically to allow closer observation

On page 30 I forgot to translate Y direction displacement.

With A it is 1km+/-500m
With B it is 30km +/- 10km
With C it is 1km +/- 500m

Page 31:

Horizontal scale is time, and vertical is hovering height. 17th July (left) to 23 July (right)

Page 32: mddile height operation, 10:00 and 20:00 on 1 August to 08:00 and 18:00 on 2 August, these refer to
the points of reflexion on the diagram.

Next press briefings are 2 and 23 August.

I will translate a little more, if JAXA are not quick enough to give their own translated version.

It's already 2 times that JAXA forgets providing English version, so here it is a workaround (when PDF contents can be properly copied in japanes font, not always true):
I downloaded the PDF
I uploaded to PDF splitter
I downloaded the ZIP with the single pages
I uploaded all single pages to one place

Now to get the translation of each page (unfortunately without images) use these links.
This because Google Translate cannot manage too long documents.

Thanks anyway to pandaneko, but it looked too a big job for a single person, better to make machines work for us! :-)
