National Space Development Agency of Japan (NASDA) postponed the launch of the H-IIA Launch Vehicle No.1 because of the malfunction of the pressure- controlling valve for the second stage liquid oxygen tank.
As a result of the cause investigation, the malfunction was due to particles generated from the filter in the valve. (Please refer to the attached drawing.)
Today, a new cleanness-assured valve was assembled to the launch vehicle, and its function was successfully verified.
Therefore, NASDA set the new launch day on August 29 (Wed.), 2001 (JST).
The launch time is between 13:00 and 18:00 JST.
