Love this Eyes application. I've never watched launch & early orbit comm ops before.

Just saw a quick clip of the separation! Very nice!

AOS at CanberraDSN via DSS45 (background), with DSS34 a few moments later. smile.gif GoldstoneDSN also acquired on time.

Sampler horn deployed!

Always great to see parts of a spacecraft to contrast with space. Imagine seeing the regolith of the asteroid just below during sampling....

As is DESPATCH/ARTSAT2, another of the microsatellites launched with Hayabusa2 (and described here), according to its Facebook page.

The idea of bringing microsatellites along on deep space missions (or rather having them piggyback on Earth orbit departure maneuvers) opens up so many new opportunities, especially in outreach and technology development (ARTSAT is focusing on collaborative signal reconstruction from hundreds of amateur ground stations as an alternative to centralized downlink, and also includes a 3D printed sculpture designed at an art school).

Thank you. This picture, I believe, was taken by a camera constructed by
private donations (me included) which amounted to JPY 26 million, especially for
Hayabusa 2. Other contributions were also invied by JAXA. The camera itself cost
JPY 12 million.

I learnt just recently from somebody's blog that Hayabusa 2 will be moored
at a Lagrangian point between the Sun and the earth. Apparently, it also was
JAXA's intention with Hayabusa 1.

I am not sure how reliable this information is. Media has said nothing of this kind,
so far. P

That's very interesting, about the spacecraft being sent to the Sun-Earth L1 point. Where did you read that? Can you add a link?

As Weywot suggested, I've made a separate thread for PROCYON.

It was a blog entry. That is all I remember. I do not think I can find it again, I am afraid. However, I will try and
find more about this by some other means. If it is true there must be sometning more somewhere. P

Lingering at a Lagrange point seems very unlikely to me, considering the trouble they take slingshotting past Earth after one solar orbit to pick up speed just to get out to where the target asteroid is located.

I have a link as follows.

http://global.jaxa.jp/article/special/haya...aguchi02_e.html

It is actually Prof Kawaguchi mentioning it. If Hayabusa 2 has enough fuel left then reacing the L1 point
should not be that difficult? P

Here is another mention of Hayabusa 2 parking.

It now looks like real. Other people seem to know and I did not! P

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.

Above link (Jiji.com) talks about a report that all 4 of the ion engines were tested at the very end of last year
and each ignited (?) properly and functioned for a few hours. They will soon test
combined use of ion engines. P
