Japan Aerospace Exploration Agency (JAXA)

The Institute of Space and Astronautical Science of the Japan Aerospace Exploration Agency (ISAS/JAXA) performed Venus orbit insertion maneuver (VOI-1) for the Venus Climate Orbiter “AKATSUKI” at 8:49 a.m. on December 7 (Japan Standard Time,) but, unfortunately, we have found that the orbiter was not injected into the planned orbit as a result of orbit estimation.
The “AKATSUKI” was launched from the Tanegashima Space Center on May 21, 2010 (JST.)

JAXA has set up an investigation team led by ISAS Director within JAXA to study the cause of the failure. We will update you with the countermeasures and investigation results.
