Japan plans to resume use of its H-IIA rocket and launch a new weather satellite as early as November to replace an aging satellite, as the investigation into a failed launch last year is almost finished, government sources said Saturday.

The Space Activities Commission is to complete a report Monday on the cause of the failed launch in November of an H-IIA rocket that was going to place into orbit two spy satellites, the sources said.

The Education, Culture, Sports, Science and Technology Ministry has told the Japan Meteorological Agency it is aiming for a launch of the new multifunctional transport satellite in November or December, according to the sources.
