A new paradigm for international cooperation in space exploration

In announcing a new Vision for the US space program, President George Bush committed the USA to “a long-term human and robotic program to explore the solar system”, via a return to the Moon, leading to exploration of Mars and other destinations. He also stated that other nations would be invited to join the vision. Many other nations have, or are developing, ‘exploration visions’ of their own. The potential for international cooperation therefore exists, both at the vision and program/project levels. This paper, based on Working Group discussions as part of an AIAA space cooperation workshop,¹ presents an approach for maximizing the return on all global investments in space exploration. It proposes an international coordination mechanism through which all these various national activities could be integrated into an inherently global enterprise for space exploration, a ‘virtual program of programs’. Within the context of the coordination, individual activities would utilize the full range of cooperative mechanisms for implementation. A significant benefit of this mode of conducting cooperation is that it would not require the negotiation of complex overarching international agreements as a precondition for initiating international activity.     

ESA strategic planning for space exploration

The European Space Agency (ESA) is pursuing an independent strategic planning process for consolidating a destination driven (LEO, Moon, Mars) space exploration strategy. ESA's space exploration strategy is driven by the goals to maximise knowledge gain and to contribute to economic growth. International cooperation is a key pillar of ESA's strategy as it is considered both, an enabler for achieving common goals and a benefit, opening new perspective for addressing future challenges. The achievement of ESA's space exploration strategy is enabled through international partnerships. The interagency coordination process conducted within the framework of the International Space Exploration Coordination Group (ISECG) plays an important role in laying the foundations for future partnerships. It has achieved so far the development of a common vision for space exploration, a common plan for implementing the vision in the form of the Global Exploration Roadmap, as well as a common approach for articulating the value of global space exploration. ESA has been a strong promoter and supporter of the interagency coordination process conducted within ISECG and thanks to its unique expertise in international cooperation the Agency has contributed to its success.     

Global space exploration 2025: Europe's perspectives for partnerships

Space exploration is an emblematic domain of space activities where traditionally only established space powers have been active. However, new actors are demonstrating great interest in it, principally for international prestige reasons, with an increasing number making ambitious plans. Complementing national endeavours, international cooperation has become a central element of most countries' exploration strategy, since the costs of doing it alone are so great. Europe's development into a fully fledged actor in space exploration requires a shared assessment of the future challenges, threats and opportunities with which it will be confronted in order to derive the best options for cooperation to lead and anticipate rather than follow and endure change.     

The US civil space sector: alternate futures

The initiation of a new vision for exploration, as articulated by US President George W. Bush on 14 January 2004, has excited much interest. This article analyzes the dynamics and potential for changes in the processes and participants in future space policy and space exploration activities. It examines a range of possible alternative paths for NASA and the US government's space exploration activities, the international space community and the private sector in the articulation and pursuit of future space exploration endeavors. It concludes that the new vision for exploration brings about both an opportunity and indeed a necessity for movement towards new and innovative methods and institutions for the effective conduct of multidimensional and multilateral space exploration activities in the future.     

A new setting for international space cooperation?

The year 2004 could be seen as the turning point for the realignment of international space cooperation for the 21st century. At the very core of this readjustment, the US space exploration initiative strives to define a new scheme for such a broad array of aspects as international scientific cooperation, the role of the space industry and the organizational framework for international space applications. This paper argues that the success of this new outline of international space cooperation depends on several conditions. First, the US initiative needs to demonstrate its long-term continuity and reliability for international partners, which will depend to no small degree on the future of the ISS and its utilization for international research. Second, international cooperation between industrial partners will continue to need political frameworks and depend on a balanced handling of know-how partnerships. Third, cooperation in space applications will need a truly international structure to further its global acceptance and outreach.     

Toward a paradigm shift in managing future global space exploration endeavors

This paper analyzes the objectives and activities of space exploration programs, and presents action plans and guidelines for a future sustainable global space exploration platform. While new cooperative mechanisms have emerged in recent decades, the now-unfolding era of global space exploration will lead to new models of cooperation, reflecting the legacy of partnerships and the evolution of a global endeavor. Consequently, the successful alignment of national and international stakeholders along lines drawn by commonality of purpose will be crucial to achieve a basis for marshalling sufficient resources for ambitious space projects, and to create necessary new political, economic, and legal frameworks. For the development of a successful global space exploration program, traditional approaches may need to be supplanted by a new paradigm including focus on information exchange, organizational knowledge, and human capital – as practiced in high-performance organizations (HPOs) – that go well beyond the current international working groups and multinational space efforts.     

Improved space safety for astronauts

The 2003 Columbia accident demonstrated that spaceflight remains a risky and dangerous human endeavor, yet there have been few ‘unofficial’ investigations into astronaut safety. This report summarizes the findings of one such study by George Washington University's Space & Advanced Communications Research Institute—e.g. that simplicity of design may be better than complexity, that cargo missions would be better carried out robotically and that all new space transportation systems should be developed to common international standards—before examining ways that international cooperation can advance the cause of space safety. In establishing future space safety standards input from a wider range of participants (industry, universities and private research institutes, as well as space agencies, etc.) will need to be sought.     

Commercialization of space activities: Legal requirements constituting a basic incentive for private enterprise involvement

Commercialization of space activities requires a legal framework for private investors and entrepreneurs in order to promote and develop this sector of industry into a fully-fledged commercial enterprise. Apart from the already existing international public legal framework of space law, rules should be created to provide a level playing field for all interested parties. These rules should point to transparency of risks and liabilities and liberalization of the various space market segments. Another legal instrument will be that of dispute resolution among participants in the arena of space activities. For the more distant future the Moon Agreement should be reassessed in the light of resources exploration, management and exploitation against the background of private enterprise involvement.     

Space development: social and political implications

Far-reaching social and political issues are implicit in any discussion of large-scale space development. This Viewpoint argues that the evolution of appropriate political institutions to deal with these issues is likely to be at least as important as the development of new technology. If large-scale space development is to take place, global international cooperation will be essential and such cooperation will have to be underpinned by enhanced institutional and legal structures. In the shorter term, an appropriate institutional response may be the creation of a World Space Agency. However, in the longer term, we should probably view a world space programme as falling within that class of global concerns that would be most appropriately managed by a federal world government.     

NASA's new Mars Exploration Program: the trajectory of knowledge

NASA's newly restructured Mars Exploration Program (MEP) is finally on the way to Mars with the successful April 7 launch of the 2001 Mars Odyssey Orbiter. In addition, the announcement by the Bush Administration that the exploration of Mars will be a priority within NASA's Office of Space Science further cements the first decade of the new millennium as one of the major thrusts to understand the "new" Mars. Over the course of the past year and a half, an integrated team of managers, scientists, and engineers has crafted a revamped MEP to respond to the scientific as well as management and resource challenges associated with deep space exploration of the Red Planet. This article describes the new program from the perspective of its guiding philosophies, major events, and scientific strategy. It is intended to serve as a roadmap to the next 10-15 years of Mars exploration from the NASA viewpoint. [For further details, see the Mars Exploration Program web site (URL): http://mars.jpl.nasa.gov]. The new MEP will certainly evolve in response to discoveries, to successes, and potentially to setbacks as well. However, the design of the restructured strategy is attentive to risks, and a major attempt to instill resiliency in the program has been adopted. Mars beckons, and the next decade of exploration should provide the impetus for a follow-on decade in which multiple sample returns and other major program directions are executed. Ultimately the vision to consider the first human scientific expeditions to the Red Planet will be enabled. By the end of the first decade of this program, we may know where and how to look for the elusive clues associated with a possible martian biological record, if any was every preserved, even if only as "chemical fossils."     

Why we need a space elevator

The goals of and vision for development of a space elevator have been discussed repeatedly. However, why we should develop one has been glossed over. This paper will focus upon the major issue—why build a space elevator infrastructure? It considers why we need a space elevator, what missions it would enable and how far it would reduce costs. There is no doubt that some major missions would be enhanced or significantly enabled by a space elevator infrastructure. Global communications, energy, monitoring of the Earth, global/national security, planetary defense, and exploration beyond low-Earth orbit are a few examples. In the end, if we are serious about extending space development and avoiding limitations on the human spirit, the reason we should build a space elevator is because we must!     

Why space exploration should be a global project

Apollo should not serve as a model for the many programs for lunar and planetary exploration currently making headway: it was a unilateral effort whose generous budget would be inconceivable today. Yet President Kennedy was an advocate of cooperation in major space missions, an attitude that makes perfect sense today, when so many agencies have ambitious exploration plans. The importance of President G.W. Bush's ‘Vision for Space Exploration’, by providing a focus for NASA and others, has been underestimated. It should give us a chance to find out whether a long-term objective of moving humans off the home planet is really feasible—surely the point of exploration.     

Japanese moon lander SELENE-2—Present status in 2009

JAXA is planning exploration missions to the moon, following upon the Kaguya (SELENE) mission., These missions aim to demonstrate some new technologies, observe the moon scientifically, investigate technical, social and political feasibility of utilizing the moon. For the first step of the missions, the phase A study of SELENE-2 has started from the summer of 2007. This mission will demonstrate the effectiveness of several technologies including precision landing, hazard avoidance, surface mobility, and night survival technologies. In situ geological and geophysical observations will be conducted to improve our knowledge on the origin and the evolution of the moon. Investigating the lunar surface conditions and its potential for in situ resource utilization will provide key information for future human exploration missions. This paper presents the current status of the SELENE-2 mission, its objectives, its design, and other important aspects of its development such as international cooperation.     

Stepping stones toward global space exploration

Several nations are currently engaging in or planning for robotic and human space exploration programs that target the Moon, Mars and near-Earth asteroids. These ambitious plans to build new space infrastructures, transport systems and space probes will require international cooperation if they are to be sustainable and affordable. Partnerships must involve not only established space powers, but also emerging space nations and developing countries; the participation of these new space actors will provide a bottom-up support structure that will aid program continuity, generate more active members in the space community, and increase public awareness of space activities in both developed and developing countries. The integration of many stakeholders into a global space exploration program represents a crucial element securing political and programmatic stability. How can the evolving space community learn to cooperate on a truly international level while engaging emerging space nations and developing countries in a meaningful way? We propose a stepping stone approach toward a global space exploration program, featuring three major elements: (1) an international Earth-based field research program preparing for planetary exploration, (2) enhanced exploitation of the International Space Station (ISS) enabling exploration and (3) a worldwide CubeSat program supporting exploration. An international Earth-based field research program can serve as a truly global exploration testbed that allows both established and new space actors to gain valuable experience by working together to prepare for future planetary exploration missions. Securing greater exploitation of the ISS is a logical step during its prolonged lifetime; ISS experiments, partnerships and legal frameworks are valuable foundations for exploration beyond low Earth orbit. Cooperation involving small, low-cost missions could be a major stride toward exciting and meaningful participation from emerging space nations and developing countries. For each of these three proposed stepping stones, recommendations for coordination mechanisms are presented.

What next for China in space after Shenzhou?

This article discusses China's ambitions in space now that it seems set to pursue human spaceflight. It suggests that, after sending its astronauts into space, completing orbital rendezvous-docking operations and placing a space lab in orbit, China will focus on the Moon with its Chang’e project. As an emerging space power, China will play a more active role in the international space community through collaboration in areas such as lunar exploration, science operations on the International Space Station, the Galileo Global Navigation Satellite System and the International Geosphere–Biosphere Program (IGBP). In particular, China will vigorously explore new opportunities to expand its cooperation with Russia and ESA to counteract Washington's attempt at containment. Meanwhile, Beijing will continue to follow its self-reliance principle to go its own way in space.     

The Global Exploration Roadmap and its significance for NASA

The Global Exploration Roadmap reflects the collaborative effort of twelve space agencies to define a long-term human space exploration strategy which provides substantial benefits for improving the quality of life on Earth and is implementable and sustainable. Such a strategy is a necessary precondition to the government investments required to enable the challenging and rewarding missions that extend human presence into the solar system. The article introduces the international strategy and elaborates on NASA's leadership role in shaping that strategy. The publication of the roadmap, a reflection of the space landscape and multilateral agency-level dialog over the last four years, allows NASA to demonstrate its commitment to leading a long-term space exploration endeavor that delivers benefits, maintains strategic human spaceflight capabilities and expands human presence in space, with human missions to the surface of Mars as a driving goal. The road mapping process has clearly demonstrated the complementary interests of the participants and the potential benefits that can be gained through cooperation among nations to achieve a common goal. The present US human spaceflight policy is examined and it is shown that the establishment of a sustainable global space exploration strategy is fully consistent with that policy.     

月球着陆器精确定点及安全着陆技术研究

在未来月球探测中,需要对一些地形复杂的区域进行探测,而在这些区域软着陆,潜在的危险性增加,这就要求着陆时具有较高的定位精度并能够自动避险。当前,由于着陆时定点的误差较大,在小范围安全地域准确着陆很难。研究了一种精确定位、安全的软着陆方式,它在软着陆过程中增加了悬停阶段。在这一阶段中,通过着陆区危险地域的识别、着陆地点位置误差的计算,加上对着陆器横向漂移的控制技术,使着陆地点的精度以及着陆生存率大为提高,能够满足未来月球探测的软着陆要求。     

Why go to the moon? The many faces of lunar policy

What is it about the Moon that captures the fancy of humankind? A silvery disk hanging in the night sky, it conjures up images of romance and magic. It has been counted upon to foreshadow important events, both of good and ill, and its phases for eons served humanity as its most accurate measure of time. This paper discusses the Moon as a target for human exploration and eventual settlement. This paper will explore the more than 50-year efforts to reach the Moon, succeeding with space probes and humans in Project Apollo in the 1960s and early 1970s. It will then discuss the rationales for spaceflight, suggesting that human space exploration is one of the least compelling of all that might be offered. The paper will then discuss efforts to make the Moon a second home, including post-Apollo planning, the Space Exploration Initiative, and problems and opportunities in the 2004 Vision for Space Exploration, and cancellation of that program in 2010.
