It's really something that Akatsuki is doing amazing science after the trials and tribulations that satellite has been through. After failing orbital insertion around Venus, it went five years in heliocentric orbit to reposition itself for insertion around Venus again. The team ended up macguyvering its secondary attitude control jets[1] for a long burn (~20 min) that they weren't designed for, but it worked and allowed for a successful insertion--albeit in a non-ideal orbit with a 9 day period instead of the originally planned 1.25 days.
