Mitsubishi Heavy Industries, Ltd. and the Japan Aerospace Exploration Agency (JAXA) decided to postpone the launch of the H-IIB Launch Vehicle No. 6 with the H-II Transfer Vehicle “KOUNOTORI6” (HTV6) onboard from the Tanegashima Space Center, which was scheduled for October 1 (Sat.), 2016 (Japan Standard Time), as unfavorable.
The new launch date will be announced as soon as it is determined.

(Reason for the delay)
A slight leak was detected from piping of the HTV6 during an air tightness test. The test is part of HTV6 launch preparations at the launch site. We will disband the HTV6 module and take necessary measures.
