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.

The H-II Transfer Vehicle (HTV) is an unmanned transfer vehicle that will rendezvous with manned facilities and deliver up to six tons of cargo. HTV is a key space transportation system technology in Japan together with the H-IIA/H-IIB launch vehicle and is designed to fully satisfy the manned safety requirements of the International Space Station (ISS) program. Therefore, the technology and its system acquired through HTV development and operation will be widely utilized in future manned transportation and lunar and planetary exploration missions.

As member of the ISS international partnership program, Japan makes essential contributions to space experiments and enables human space activities through the use of HTVs. JAXA has initiated technical research into cargo return from orbit as a next step toward on-orbit services. The HTV has been used in research as a service module, and a return vehicle called HRV (HTV Return Vehicle) was added to enhance its performance. The combined vehicle is called HTV-R and it will enable JAXA to recover various samples from experiments conducted on the ISS.

HTV (H-II Transfer Vehicle) is the first Japanese un-manned service vehicle that will transport several pieces of equipments to ISS (International Space Station) and support human activities on orbit. HTV will be launched by the first H-IIB rocket in September 2009 and JAXA will have the capability to access LEO (Low Earth Orbit) bases with enough volume/weight as the human transport system. This paper is the preliminary study for developing a manned spacecraft from the HTV design and includes clarification of necessary development items. In addition, missing parts in the current HTV design are identified with some analysis, such as LES (Launch Escape System), which is mandatory for all human transport systems.

Japan contributes essential services to space experiments and enables human activities included as part of the international partnership of the ISS program by utilizing the HTVs (Kounotori). As the next step toword on-orbit service, JAXA has commenced technical research into cargo return from orbit. The HTV was used in research as the base design and a return vehicle was added to enhance performance. The combined vehicle is called the "HTV-R". HTV-R enables JAXA to recover various samples of experiments conducted on the ISS and equips a new return vehicle called as "HRV (HTV Return Vehicle)" for the enhanced function. The HRV will fly autonomously and conduct lifting re-entry into the atmosphere by controlling the attitude and trajectory to a predefined splashdown point. Now two types of vehicle concepts are being investigated. One uses an HTV as the base system for orbital flight and minimizes the initial cost of HTV-R program, and the other integrates the HTV components into a new vehicle, optimizing the on-orbit functions to minimize the recurring cost.
