This is just in, from a lunch time NHK TV news here.

Hayabusa 2 will be launched on 30 November from Tanegashima space centre. So, that will be an H2-A
rather than the Epsilon, meaning a piggy-back, I think. P

My curiosity has vapourised thanks to a recent short newspaper article in the Yomiuri.

There was a similar article recently, which said that the H2A launcher will have a special
coating on its fuel tank and will rotate during its long flight in order to keep fuel loss to a minimum.
I was curious, "long?" , because usual 15 minutes did not seem too long to me, anyway,
but I did not bother to find out.

This Yomiuri article clarified it for me, as follows.

"On 20 October, MHI revealed to the press the H2A 26 launcher, which will be launched on
30 November with Hayabusa 2 on board. It is a 2 stage rocket and its 1st stage is
37m long with 4m diamter and 2nd stage 11m long.

This time, it will take as long as 2 hours before spacecraft seperation in order to reach its
very distant target. In order to keep fuel loss to a minimum as the liquid hydrogen
vapourises inside the tank its 2nd stage fuel tank has been coated white."

I have been used to the launch of earth bound satellites. This article did not mention rotation, though. P

There is a short article in today's Asashi (local newspaper) about the launch of Hayabusa 2.
In it I find that Hayabusa 2 will not come back into the atmosphere. Instead it will go away back into space.
Nobody has ever told me that. Did we know it? P

Some adorable Hayabusa 2 and MASCOT manga. Think I'll print these out and have my kids color them! The artist is Go Miyazaki.

I was confused with the "first" frame of that comic until I realized that it read from top RIGHT down and then top left down!

I have since asked around amongst my friends here who are space matters interested.
None of them had known, and do by now. So, my guess is that the decision is
fairly recent. Perhaps, they at ISAS do not want to see the craft destroyed after a
good job (big assumption!).

I am being a typical Roman citizen and want to see the show, but then, yes,
it may be pity that the craft is lost that way. After all space itself may be a museum. P

It may not be lost. Perhaps it could have a life beyond its prime mission like Stardust did.
