In a brief media statement, the Japan Aerospace Exploration Agency (JAXA) announced that it has canceled today’s planned launch of an H-IIA rocket, which is carrying a navigation satellite that is designed to augment the Global Positioning System (GPS) for the Japanese region.

Details not immediately clear


According to the statement, JAXA and its lead contractor, Mitsubishi Heavy Industries, Ltd., jointly decided to cancel the launch, which is expected to be the 35th flight of the H-IIA launch vehicle. JAXA indicated that the flight was canceled “due to the necessity of additional examinations around [sic] rocket propulsion system.” However, the statement did not indicate whether the problems were with the H-IIA launch vehicle or the satellite’s R-4D engine. JAXA said that a new launch date would be announced “as soon as it is determined.”

The payload, MICHIBIKI Quasi-Zenith Satellite #3, is part of a Japanese-built satellite-based augmentation system for the GPS; the system is designed to support highly precise and stable location services in Japan as well as those counties in the Asia-Oceania region with similar longitudes, such as Indonesia and Australia.
