Launch Postponement of the H-IIA Launch Vehicle No.1

August 22, 2001 (JST)

National Space Development Agency of Japan

The National Space Development Agency of Japan (NASDA) scheduled to launch the H-IIA Launch Vehicle No.1 (H-IIA·F1) on August 25, 2001, but decided to reschedule the launch to a later date. It is primarily because a malfunction was found in a pressure controlling valve of the second stage liquid oxygen tank on August 19. The valve was removed and sent back to the plant for further cause investigation, but its shipping back was delayed due to Typhoon No. 11, and that also contributed launch postponement. NASDA would like to allocate sufficient time for the cause investigation.

The new launch day depends on the progress of the cause investigation, and the earliest possibility is August 28 in the current estimation. The date will be announced as soon as it is determined.
