As the European Union takes tentative steps towards creating a “rapid reaction force” able to operate independently of NATO, an important question is what capabilities that force must have in order to operate effectively. Among those capabilities is the use of space systems for communications and intelligence applications. This article examines the prospects for an independent security space capability in Europe, and the implications of the emerging European interest in space autonomy for US policy.  相似文献

When US President George W. Bush on 14 January 2004 announced a new US “Vision for Space Exploration”, he called for international participation in “a journey, not a race”, a call received with skepticism and concern elsewhere. But, after a slow start in implementing this directive, during 2006 NASA has increased the forward momentum of action on the program and of discussions on international cooperation in exploring “the Moon, Mars, and beyond”. There are nevertheless a number of significant top-level issues that must be addressed if a cooperative approach to human space exploration is to be pursued. These include the relationship between utilization of the ISS and the lunar exploration plans, integration of potential partners’ current and future capabilities into the exploration plans, and the evolving space-related intentions of other countries.  相似文献

This response to Alex Roland's article, ‘Priorities in space for the USA’, argues that his analysis and conclusions are based on shaky historical evidence. Professor Roland's interpretation of NASA's priorities since 1959 is challenged, and it is pointed out that the manned spaceflight programme has widespread support in the USA. The most important issue, raised by the article but not treated extensively enough, is whether the pursuit of the widely accepted emphasis on manned spaceflight is a large-scale societal mistake.  相似文献

This article provides an overview of NASA's plans to encourage commercial use of the International Space Station (ISS). It examines the reasons driving such commercialization and highlights those private companies currently most interested in undertaking profit-making operations on the station, as well as discussing those activities most likely to be seen as commercial possibilities. The steps NASA is taking to stimulate private interest are enumerated. Various unresolved issues are raised, such as the legal issues associated with commercial research, charging policy for in-orbit operations and ‘metering’ of in-orbit resources. It is noted that the international dimension of the ISS has thus far received little consideration in the USA.  相似文献

A newly released tape of a 18 September 1963 conversation between President Kennedy and NASA Administrator James Webb has been interpreted by some as showing that the president was looking for a way out of his Apollo commitment. This commentary analyses the meeting – in which Webb did most of the talking – and concludes instead that Kennedy was concerned about how to keep the program going in the face of growing criticism of its cost and goals. In particular there was discussion of how to ensure that his support for Apollo did not harm his chances of re-election. To Kennedy, giving Apollo a military rationale seemed the best way to ensure its support.  相似文献

2010 saw both the unveiling of a new US National Space Policy and the announcement of a fundamentally different strategy for US human spaceflight that would move from the NASA-government-led Apollo-style approach to a greater reliance on the private sector and international cooperation. This viewpoint puts forward arguments on why change in the US approach to human spaceflight is needed, while acknowledging that achieving it in the face of vested interests and threats to jobs and livelihoods is extremely difficult. It suggests that greater US recognition of the need to ensure the sustainability of space activity (by addressing debris, radio-frequency interference and potential deliberate disruption of spacecraft), and an apparent willingness to countenance international norms to govern space activities, could be the new policy’s most lasting heritage.  相似文献

John M. Logsdon   《Space Policy》2011,27(1):15-19
In 2010 the administration of President Barack Obama proposed a dramatically new approach to future US human spaceflight. That new strategy was immediately controversial. This article traces the origins of the new spaceflight strategy and the continuing political debate with respect to its acceptance.  相似文献
