Ohhhh, they mean to park it at a Lagrange point after returning from the asteroid. That makes more sense.

The purpose appears not to be to conduct any particular science there, but to test the general idea of parking things at Lagrange points.


ISEE-3 proved the feasibility leaving a lagrange point to visit small bodies. Not much to prove. I'd say the purpose is to wait for the team to find a feasible follow-on, or determine there is none.

As of yesterday Hayabusa2 is doing well, so say the press here,
flying at 22 milliom km away, and will change direction in December. P

Not really, a short article of 25 January only says that it is at about 20 million km away,
doing substem testings. Actually, their occasional English translations are very good.

Also, no news about hydrogen observation so far. All next week I will be away in
Borneo jungles. P

In a Q&A session posted earlier, it was reported that they were having difficulty deciding on a name for the asteroid. Naming "Itokawa" was easy, but they are still undecided about the final name for 199JU3. (JAXA proposing the name "Itokawa" is like NASA choosing the name "von Braun")

The process of giving 1999 JU3 a proper name, subject to IAU rules has begun. Submissions being accepted:

Oct. 5, 2015 Updated
“Ryugu” was selected as name of Hayabusa2 target asteroid

Asteroid 1999 JU3, a target of the Asteroid Explorer “Hayabusa2,” was named “Ryugu”.
One major reason for the selection was that, in the Japanese ancient story “Urashima Taro”, the main character, Taro Urashima, brought back a casket from the Dragon’s palace, or the “Ryugu” Castle, at the bottom of the ocean, and the theme of “bringing back a treasure” is common as the Hayabusa2 will also bring back a capsule with samples. It was selected among 7,336 entries.
Thank you very much to so many of you who took part in the naming campaign.

According to the Yomiuri, a local Japanese newspaper with about 10 million circulation/day
Hayabusa 2 conducted an earth swingby successfully on 3 December and left its near earth orbit.

It is currently flying, as of midnight 14th December, 4.15 million km away from the earth,
at a speed of 32.31 km/second without problems.

The former is wet and the latter dry, so all is well!
