Administrative reform of Japanese Space Policy Structures in 2012

In Japan, there are several government ministries and agencies with important roles in the development and use of space. In 2012, Japan restructured its administrative organs related to the development and use of space through legal amendments to the original acts that established these organs. Although this was an important administrative reform that took four years of planning and discussion to accomplish, this restructuring has not been communicated well outside of Japan. This study provides the first comprehensive overview of the recent legal changes in Japanese space policy. In contrast to some reports, the Ministry of Education, Culture, Sports, Science and Technology (MEXT) still has primary responsibility for the finances and personnel of the Japan Aerospace Exploration Agency (JAXA). This continues to be true even after the Cabinet Office begins its new role as the focal point for formulating Japanese space policy. It remains to be seen how the policy direction of the Cabinet Office will interact with the operational, financial, and personnel responsibilities of MEXT. I argue that knowledge of the roles of MEXT and the Cabinet Office in space policy, and the tension between the two organizations, is key to understanding Japan's future space policy decision-making process. By tracing the history of Japanese space policy since 2001, I also suggest that if bureaucrats had thought more deeply before making major reforms to space policy and its administration, there would have been less confusion over the development of national space policy this past decade. This paper concludes by identifying some key elements to monitor in the coming years of Japan's space policy.     

The eagle eyes the dragon in space—A critique

China's space policy and its purpose have become an increasingly contentious subject. This paper critically examines the claims, made by Ashley Tellis, among others, that China has a space strategy decided and coordinated by the Chinese military and dedicated to defeating superior US power locally in an asymmetrical war, and that it is this military space strategy that drives China's single-minded pursuit of space science and technology and the development of China's space programme. To do so, the paper conducts two investigations: into the declining role of the Chinese military in China's foreign and security policy making and its limited influence in formulating China's grand strategy; and the other into the contingent history of China's two space programs, Shenzhou and Chang'e, which have largely been driven by civilian scientist communities, rather than the military. In so doing, I argue that the claims of China's ‘military space strategy’ are over-imaginative and serve a particular political purpose. The social imaginary of a threatening China produced by the US strategic gaze at China in space, I further argue, has dangerous policy implications.     

Taking a common-pool resources approach to space sustainability: A framework and potential policies

This paper examines Nobel Prize Winner Elinor Ostrom's principles for sustainable governance of common-pool resources (CPR), capturing the best practices of CPRs over the years, which avoid the “Tragedy of the Commons” without being either completely privatized or controlled by a Leviathan entity. Ostrom's principles highlight, inter alia, the need for clear boundary definitions, rules tailored to fit the domain, who has a say in formulation of collective-choice agreements and operational rules, monitoring of behavior, graduated penalties, and conflict resolution mechanisms. In the context of the space domain they highlight issues such as the definition of where space begins, gaps in the existing liability regime, the concept of collaborative space situational awareness, and how best to include emerging and developing space actors in negotiations and decision making. The paper concludes that Ostrom's principles highlight specific areas on which to focus initial space sustainability efforts and national and international policy. It also recommends further analysis into how best to translate her principles to the space domain, where they may not be wholly applicable because of the unique nature of space, and how to evolve space governance institutions and mechanisms to best suit the unique environment of outer space.     

Enacting Japan's Basic Law for space activities: Revolution or evolution?

In June 2012, four whole years after the Basic Space Law mandated a fundamental reorientation of Japan's space policy objectives towards applications, including national security and the use of space as a diplomatic tool, legislation was passed by Japan's Diet that alters who controls Japan's space policy. The new legislation involves a curious compromise between competing aims and objectives of different parts of Japan's central bureaucracy. But it also clearly represents a break from the past and potentially a decisive step toward new directions for Japan's governmental space efforts. Contextualizing the deeper and immediate background, this article seeks to elucidate just how deep, or indeed shallow, some of the forthcoming changes are.     

A normal space power? Understanding ‘security’ in Japan's space policy discourse

With the enactment of its ‘Basic Space Law’ in 2008, a significant shift occurred in Japan's space policy away from a narrowly circumscribed interpretation of the concept of space for ‘peaceful purposes’ to a broad understanding of space for ‘security’. Viewed in a global context, Japanese space policy appears symptomatic of a broadened and more malleable understanding of space for security purposes, as already advocated by several other leading spacefaring powers, and proponents of this understanding of space for security argue that this is consistent with international standards and the expectations of a ‘normal’ space power. By attempting to redefine understandings of ‘peace’ and ‘security’, however, the Basic Space Law and subsequent direction of Japanese space policy raise complex and ongoing issues over the interpretation of Japan's ‘Peace Constitution’. This article reviews policy and academic discussions of the recent evolution of Japanese space policy in this respect, arguing that greater emphasis on ‘security’ – understood in a deliberately broad sense in policy terms – has been key to articulating and justifying the reformulation and redirection of Japanese space policy, but that this also brings with it room for ambiguity over the exact nature of Japan's space ambitions at both national and regional levels.     

China's rise in space and US policy responses: A collision course?

China's opaque politics present particular difficulties for US space policy. Heavily invested in and reliant on space, the US will closely monitor China's burgeoning space program. New space powers, and the increasing use of space generally will further create significant challenges, most particularly to the reliance of states on space for national security. In order to maintain its space capabilities, the US will have to decide between securing this via multilateral and co-operative uses of space, or through trying to maintain a level of dominance over other space actors. While very gradually shifting away from the latter position, Washington's policy choices are complicated by the lack of a clear Chinese space strategy. While the Chinese space program, and its wider intentions, are opaque, tenure of a more cooperative approach course might prove fragile.     

Talking space: The European Commission's changing frames in defining Galileo

This paper traces the way in which the European Commission has framed and reframed the issue of EU satellite navigation over 20 years. It investigates how the EU's agenda-setter has ‘talked about’ space policy, with a particular focus on Galileo, and how its own institutional discourse – as revealed in its communications throughout the agenda-setting stage of Galileo's ‘definition’ phase – evolved in the 1990s through the use of ‘frame sets’. In so doing, it illustrates the ways in which, over time, the EU's executive has ‘projected’ the issue of independent satellite navigation capabilities as being politically and economically desirable for Europe, and has sought to persuade decision makers of its cross-policy relevance and potential economic, social and security benefits. The article deconstructs official documents and engages in a close-up analysis of policy formulation, to identify nascent, evolving and mature frames in the definition of Galileo.     

Japan's future in space

Japan's Consultative Committee on Long Term Policy was established within the Space Activities Commission to consider how the country's space activities should proceed. The Committee was asked to take a long-term viewpoint, considering the rapid changes in both domestic and overseas space activities. This report is an edited version (and unofficial translation) of the Committee's report, published in May 1987. It outlines the significance of space activities for Japan, considers how they have developed during this century, forecasts development after the year 2000, and presents proposals for the execution of Japan's space development.     

The contest for leadership in East Asia: Japanese and Chinese approaches to outer space

Japan and China, as two advanced spacefaring nations in Asia-Pacific region, are often referred to as rivals in space. China's successful manned space launch program in 2003 and ASAT test in 2007 were considered as turning points which potentially introduces a “space race in Asia”. This article argues that there are three defining arenas in a space race: competition for prestige or soft power, competition over military capability or hard power, and competition of international services or public goods. It analyzes the objectives, norms and logics of space policy in Japan and China, and argues that these two countries have quite different thinking over what to do in space, explaining that they are playing different games in the first two arenas. However, Japan and China are competing for leadership and influence over the region. APRSAF and APSCO, two similar regional space organizations, are the vehicles for this competition. It concludes that there is a space race only in the third arena as a competition for leadership in Asia.     

The CPR approach to space sustainability: Commentaries on Weeden and Chow

Space sustainability is emerging as a core element of national policy and international initiatives. At this time, however, a coherent strategy and supporting policies have not been developed. To initiate a conversation to develop such a strategy, the authors have applied the principles developed by Elinor Ostrom for terrestrial common-pool resource (CPR) governance to near-Earth orbit in space. A concern arises as to whether Ostrom's eight principles are a good “fit” for application to space CPR because of the unique physical characteristics of space and the legal underpinnings of our presence there. This commentary will address selected issues raised by Weeden and Chow, and suggest alternative ways to approach near-Earth orbit sustainability.     

Station keeping of a solar sail around a Halo orbit

Solar sails are a concept of spacecraft propulsion that takes advantage of solar radiation pressure to propel a spacecraft. Although the thrust provided by a solar sail is small it is constant and unlimited. This offers the chance to deal with novel mission concept. In this work we want to discuss the controllability of a spacecraft around a Halo orbit by means of a solar sail. We will describe the natural dynamics for a solar sail around a Halo orbit. By natural dynamics we mean the behaviour of the trajectory of a solar sail when no control on the sail orientation is applied. We will then discuss how a sequence of changes on the sail orientation will affects the sail's trajectory, and we will use this information to derive efficient station keeping strategies. Finally we will check the robustness of these strategies including different sources of errors in our simulations.     

US export controls and Canadian autonomy to collaborate on international space missions

Canada is a space power with unique technical niches that support opportunities for collaboration on space technologies. When U.S.-origin space technologies are involved Canada's ability to collaborate internationally may be conditional on US law and policy. As a result, US export control law can be directly linked to the success or failure of Canadian collaboration. This article examines the strategic impact of U.S. export controls on Canadian autonomy to collaborate on international missions, including multi-use missions. Canadian space export control policy is also examined more broadly with the goal of providing specific policy recommendations that will enhance Canada's future as an international space actor.     

Explaining public support for space exploration funding in America: A multivariate analysis

Recent studies have identified the need to understand what shapes public attitudes toward space policy. I address this gap in the literature by developing a multivariate regression model explaining why many Americans support government spending on space exploration. Using pooled data from the 2006 and 2008 General Social Surveys, the study reveals that spending preferences on space exploration are largely apolitical and associated instead with knowledge and opinions about science. In particular, the odds of wanting to increase funding for space exploration are significantly higher for white, male Babyboomers with a higher socio-economic status, a fondness for organized science, and a post-secondary science education. As such, I argue that public support for NASA's spending epitomizes what Launius termed “Apollo Nostalgia” in American culture. That is, Americans benefitting most from the old social order of the 1960s developed a greater fondness for science that makes them more likely to lament the glory days of space exploration. The article concludes with suggestions for how to elaborate on these findings in future studies.     

Space security through the transatlantic partnership

On 12–14 June 2011, a conference was convened in Prague entitled ”Space Security through the Transatlantic Partnership“, co-sponsored by the European Space Policy Institute (ESPI) and the Prague Security Studies Institute (PSSI). It was the first non-governmental transatlantic conference of its kind dedicated to this topic, attended by over 100 senior space policy officials and high-level representatives of multilateral institutions, NGOs, academia, and industry from Europe, the USA, and Japan. The overarching goal of the conference was to solicit and assess both converging and diverging views on the multifaceted subject of space security and to seek to establish an on-going “Track II” non-governmental process designed to assist with the crafting of a future architecture for the management of this key dimension of space policy on a trilateral, and eventually global, basis. This report summarizes the proceedings.

Planning the post-Apollo space program: Are there lessons for the present?

The current debate over the future of human spaceflight in the USA has been a fascinating, and troubling, exercise in futility for those inextricably committed to an expansive vision of human exploration and development of space. The retirement of the Space Shuttle, originally set for the end of 2010 but later extended into 2011, the technical and funding problems of the Constellation follow-on program that led to its cancellation in 2009, and the emergence of commercial vendors who might be able to offer human access to Earth orbit have all complicated the current environment. In view of this situation, the question may be legitimately asked: what might we learn from earlier efforts to develop a human spaceflight capability the last time such a transition took place? Using the post-Apollo transition from the ballistic capsule to a winged, reusable vehicle as a case study, this article seeks to illuminate the planning, decision-making, economic, and political issues that have arisen in this policy debate. It suggests that a web of interlocking issues—only one of which was technical—affected the course taken. Instead, politics, economics, social and cultural priorities, values, and institutional considerations all helped to frame the debate and shape the decision.     

Forging a closer Europe–Japan strategic partnership: The space dimension

This viewpoint explores how a strengthening of Europe–Japan cooperation in four categories of space-related activities (exploration and access to space; Earth observation and related applications; industry-to-industry cooperation; and space security) can contribute to the EU–Japan strategic partnership more broadly. It is argued that integrating key space portfolios into existing venues and agendas for bilateral consultations and decision-making has the potential to bolster the overarching objective of deepening further political, economic, commercial, societal and cultural relations.     

Gathering news from space

Developments in remote-sensing technology have prompted suggestions that the news media could soon make routine use of newsgathering from space. A satellite system dedicated to this purpose (a ‘Mediasat’) could supply critical information. Government policy makers, however, fear that the media's use of such technology could affect national security, foreign relations and personal privacy. This article assesses US government policy on current and future newsgathering from space, and the technical potential for a Mediasat system. The authors raise doubts about the commercial viability of Mediasat, and point out that existing media sources already provide information on news stories. They conclude that concerns over the use of data from space will have to be met on a case-by-case basis as the media gain experience, using the same criteria now applied to balance the right of freedom of information with the need for national security.     

Inertia-independent generalized dynamic inversion feedback control of spacecraft attitude maneuvers

The generalized dynamic inversion control methodology is applied to the spacecraft attitude trajectory tracking problem. It is shown that the structure of the skew symmetric cross product matrix alleviates the need to include the inertia matrix in the control law. Accordingly, the proposed control law depends solely on attitude and angular velocity measurements, and it neither requires knowledge of the spacecraft's inertia parameters nor it works towards estimating these parameters. A linear time-varying attitude deviation dynamics in the multiplicative error quaternion is inverted for the control variables using the generalized inversion-based Greville formula. The resulting control law is composed of auxiliary and particular parts acting on two orthogonally complement subspaces of the three dimensional Euclidean space. The particular part drives the attitude variables to their desired trajectories. The auxiliary part is affine in a free null-control vector, and is designed by utilizing a semidefinite control Lyapunov function that exploits the geometric structure of the control law to provide closed loop stability. The generalized inversion singularity avoidance is made by augmenting the generalized inverse with an asymptotically stable fast mode that is driven by angular velocity error's norm from reference angular velocity. Asymptotic tracking is achieved for detumbling maneuvers as the stable augmented mode subdues singularity. If the steady state desired quaternion trajectories are time varying, then asymptotic tracking is lost in favor of close ultimately bounded tracking because the stable augmented mode continues to be excited during steady state phase of response. A rest-to-rest slew and a trajectory tracking maneuver examples are provided to illustrate the methodology.     

What is the state of play in European governance of space policy?

The European way of doing space differs from others in that, while carried out cooperatively, there is no fully integrated space policy. This is inevitable in a non-sovereign entity whose members do not have the same priorities in many vital sectors such as energy, industry and political economy, and has nevertheless produced some excellent programmes. But, against the background of the worldwide increase in space players and capabilities, Europe's current lack of ambition and foresight, and its limited ability to respond to external developments are worrying. It needs to be more open about its governance and financing plans, something missing from the latest European Commission communication. In these difficult economic times a complete rethinking of future space plans would enable Europe to prioritise on the strategic niches which must be preserved, while proper investigation of the management failures of the flagship programmes might help avoid such difficulties in the future.
