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.
