In just a few hours, Venus will have a second orbiter. Japan's Akatsuki is due to start firing its orbit insertion engines on December 7 at 08:49 Japan time (which is today, December 6, 23:49 UTC / 15:49 PST).
There has already been a successful trajectory correction maneuver today, lining the spacecraft up for orbit insertion. (EDIT: This was not correct; I misunderstood the Google translation. The last rocket firing was on December 1.) A timeline of today's plans is below. I edited it from a Google translation of this Japanese-language website, so any errors are mine.
|Time w.r.t. closest approach
|Dec 6 23:49:00
|Orbit insertion burn begins
|Ground station communication blackout expected
|Dec 7 00:01:00
|End orbit insertion burn
|Communication should resume
|Enter into Venus' shadow
|Exit from Venus' shadow
|Orient attitude to Earth for orbit determination
|Switch between medium-and high-gain antennas
|Orbit determination should be complete; decide if further course correction necessary
Via Twitter I've heard that there will be a live webcast (in Japanese of course) beginning at 23:00 UTC / 15:00 PST at this website.
Since the orbit insertion happens during after-school time for me, I am, sadly, not going to be able to follow it live, though I'll be monitoring Twitter when I can. I recommend following cosmos4u; you may also want to bookmark the Google translation of Akatsuki's own Twitter feed and the Google translation of the mission website. For any machine-translated websites, wherever you see the word "somehow," you should mentally replace it with "Akatsuki."
