8. National Policies • The Basic Strategy(Sep 9,2004) • Council for Science and Technology Policy • (chaired by Prime Minister) • - Significance of Space development and utilization are • Maintaining independence in the global society, • Wide-ranging impact on the socio-economy, and • Contributions to the national pride by undertaking the challenge to explore space as the human frontier. • Space development and utilization is essential as a key technologyfor the sustainable development of Japan. • Our basic policy is to maintain our capability to access to space.

9. ＪＡＸＡ　Vision Vision (1) Contribute to building a secure and prosperous society through the utilization of aerospace technologies Vision (2) Contribute to advance our knowledge of the universe and broaden the horizon of human activity Vision (3) Develop the capability to carry out autonomous space activities through the best technologies in the world Vision (4) Facilitate growth of the space industry with self-sustenance and world class capability Vision (5) Facilitate the growth of aviation industry and aim for technological breakthroughs for future air transportation

10. JAXA Vision Key message from JAXA Vision related to STS Development of capability for autonomous space activities • Implementation (Up to 10 years): • Maintain and evolve the mainstay launch vehicle by • stable operation of H-IIA • Develop launch vehicles with high reliability able to • carry people safely • Continuous operation of the unmanned cargo • transportation vehicle (HTV) to ISS • Develop inter-orbital transfer vehicles and unmanned • recovery vehicles based on HTV

11. Conclusion • Maintain our own transportation capability • Promote space exploration in coorporation with international partners as ultimate goal of space development for humankind.
