The IBUKI was launched at 12:54 p.m. on January 23, 2009 (JST.)

Japan Aerospace Exploration Agency will start the initial functional verification phase 2 to check the
onboard equipment function for about three months. Phase one was the Critical Operation Phase whereinthe period of preparation for the initial functional verification operation from the launch phase until shifting the attitude control system to the regular operation mode including satellite separation from the launch vehicle and solar array paddle deployment after that.

The phase 2 includes the Initial Functional Verification Phase wherein the period to verify the functions of the satellite itself and its onboard devices including observation sensors.

The satellite is currently in good condition.
