According to this website hosted by Goddard Space Flight Center, Kaguya has been given a new launch date of September 13. Its launch was delayed by the discovery that condensers in its two mini-satellites had been installed upside down.
The second week in September is going to be crazy busy! Dawn's launch, Cassini's encounter with Iapetus, now Kaguya is launching. That will put a huge strain on the Deep Space Network, which will have to support both launches and somehow also receive all of Cassini's exciting and unprecedented data from the Iapetus encounter.
