This year will be a major milestone for JAXA with the launching of the new heavy rocket H-IIB and HTV (H-II Transfer Vehicle). Together they will form an important infrastructure for transporting supplies, equipment, and experiment modules to the LEO (Low Earth Orbit) station and will be the basic design of a manned spacecraft in the future. In the previous paper in ISTS in 2008, a preliminary study focusing upon the LES (Launch Escape System) and parametric analyses for its abort system was reported. The missing parts of a manned flight utilizing the combination of HTV and H-IIB are selected as the main structure in this paper. In addition, the progress made in spacecraft design is included along with its development plan in which important development items that have not yet been investigated enough in Japan are identified.
