a release in English http://www.jaxa.jp/projects/sat/ikaros/topics_e.html
in fact Emily I think there is a small error in your blog post: QUOTE January 6, 2012 was the last time JAXA had contact with IKAROS but actually: QUOTE The IKAROS was confirmed to have shifted itself into hibernation mode (or shutting down its onboard equipment due to low power generation) sometime before Jan. 6, 2012. I have seen somewhere 24 December 2011 as the date of the last contact. If only I could remember where... |

according to the latest blog entry http://www.isas.jaxa.jp/home/IKAROS-blog/?itemid=1002 reviving of IKAROS has been progressing slowly. they recently switched communications from the LGA to the MGA, which will probably mean that telemetry data should now start streaming at a much faster rate

Disorganization of project teams, Space missions "Hayabusa" and "Ikaros"
IKAROS project team disbanded. I am told that tracking support should continue |

My wife's rough translation is that it's over 200 million km from Earth & hasn't been receiving enough solar power to operate; she used the word "sleep". Apparently in June it's expected to operate well enough to return (I assume) engineering data, but 7 months from now that'll be effectively EOM.
(Again, VERY rough translation; Kay wants to always state that she's got no background at all in space-related matters, and modern Japanese slang (esp. of the Net variety) is unfamiliar to her.) -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

Has anything more been said about the proposed late 2010s successor mission to Jupiter & the Trojan asteroids? Is that still planned?

Just wondering... if Ikaros - like now - is still operating in early 2017, wouldn't it by orbital mechanics be doing another flyby of Venus at that point (10 Venus orbits or 7 Ikaros orbits after the Dec 2010 flyby)?
Ikaros has so far come out of hibernation during these perihelion phases, right (sometime around... now, this year)? |

That might depend on the solar sail effect on the orbit - even if not intentionally 'sailed' during those orbits, the sail may have an effect, and the orbit may not be as straightforward as another spacecraft's would be.
