Mitsubishi Heavy Industries, Ltd. and the Japan Aerospace Exploration Agency (JAXA) launched the H-IIA Launch Vehicle No. 24 (H-IIA F24) with the Advanced Land Observing Satellite-2 “DAICHI-2” (ALOS-2) onboard at 12:05:14 p.m. on May 24, 2014 (Japan Standard Time, JST) from the Tanegashima Space Center.
The launch vehicle flew smoothly, and, at about 15 minutes and 47 seconds after liftoff, the separation of the DAICHI-2 was confirmed.
We would like to express our profound appreciation for the cooperation and support of all related personnel and organizations that helped contribute to the successful launch of the H-IIA F24.
At the time of the launch, the weather was fine, a wind speed was 3.4 meters/second from the east and the temperature was 24.4 degrees Celsius.

*1 Quick estimation value prior to the detailed estimation
*2 The values are updated ones based on actual measurement data such as engine performance which are unique for the H-IIA F24 engines. Therefore, they are slightly different from the values in the Launch Plan.
*3 When the combustion chamber presser becomes 10% against the largest combustion pressure.
*4 The definition of SRB-A jettison is the separation of the rear brace.
