国の宇宙探査に関する方針: Government Policy for Space Exploration
・ 宇宙基本計画では宇宙探査について以下のように記述されている
 大規模なプロジェクトについては、学術のみの目的では実施が困難になりつつある面があり、国際協力や産業競争力強化など、多様な政策目的との連携など、プロジェクトの企画・立案や選択にあたり、学術コミュニティーと政策担当者との十分な検討が必要である。
 今後とも一定規模の資金を確保し世界最先端技術の成果を目指す「宇宙基本計画」（平成２５．１）

・ “ Basic Plan on Space Policy “ indicates the followings for space exploration.
 The large-scale projects related to space science and space exploration are difficult tocarry out for purely academic purposes. On planning or selecting a project, academic
community members and policy makers should examine the project together to link it tovarious policies, including international cooperation and the enhancement ofinternational competitiveness.
 It is necessary to make full use of the scheme and ensure a constant amount of funds,
in order to achieve cutting edge breakthrough.

“Basic Plan on Space Policy”（Jan.2013）まとめ : Summary
・ 我が国の宇宙機器産業は官需への依存度を高めている
・ 企業内の従業員数の減少と研究開発費の削減は企業の独自活動を縮小した・ 企業が宇宙探査に独自の資源を投入する余裕は少なくなった・ Recently, Japan’s space industry heavily relies on the government demand.
・ The reduction of employees and R&D expenditure in the industry caused
shrinkage of its own activities.
・ These circumstances implies that it cannot afford for the industry to spend
its own resources for space exploration.

・ 政府計画の長期的な方向性の明示が必要となっている
・ 新技術の開発機会を創出するプログラムが期待される
・ 国際協力によって各国の宇宙予算の効率的な運用が期待される・ Clarifying the long-term program in the government level is expected.
・ Programs promoting development in advanced technology are expected.
・ International cooperation is expected for efficient uses of national budget.
