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

For decades, Western European nations have been comparatively uninterested in the military use of space, largely content to rely on the far greater resources of the USA in this area. Today, however, the traditional belief that the security requirements of ‘the West’ are synonymous with those of the USA is increasingly open to challenge. A new European defence identity is emerging, keen to achieve greater autonomy in the security field, albeit remaining within the overarching framework of NATO. Consequently there is a growing requirement for indigenous European capabilities in terms of military space assets. This requirement has been met in part by the establishment, by the Western Union, of a satellite centre in Spain, which currently analyses commercially procured satellite imagery. The centre's capabilities may be expanded if the WEU states decide to add a space-based element — either their own satellite system, or participation in an existing multinational programme. Such a decision is due to be taken towards the end of 1995. This paper concludes by briefly examining the political and security implications of such a decision. 相似文献

The RUSI Space and UK National Security Conference was held in London, 14 June 2011. Alixe Buckerfield de la Roche reports on some of the key themes discussed, including the increasing merger of space and cyber, the growing urgency in calling for development of robust and effective regulatory frameworks for orbital management, and the challenges surrounding national resilience achieved through space situational awareness. At RUSI’s 12th Missile Defence Conference held the same week Secretary General Rasmussen gave an address on NATO’s missile policy—focusing on partnerships and collaboration. His comments intersect aptly with the Space and UK National Security conference themes and are therefore included here. 相似文献

Transatlantic cooperation has played a key part in developing Europe's capabilities in space, but this has been despite serious drawbacks in the legal status of the agreements concerned. This article traces the history of transatlantic space relations and highlights the misunderstandings that have arisen. These stem from the precedence given in the USA to domestic laws and financial interests over all international agreements except formal treaties, which are generally not considered suitable for scientific and technical agreements. The article concludes with a discussion of how more stable and equitable relationships could be achieved. 相似文献

为改善在空间站长期值守的航天员的业务生活,提出建立空间站网吧,为航天员提供因特网服务的构想。为此分析研究空间站空间因特网服务系统及其关键技术,提出空间站空间因特网服务系统构建方案。结合这一系统构建方案,一是研究解决了支持复杂异构网络运行的空间因特网网络协议设计技术,空间站空间因特网直接采用TCP/IP协议,并通过系统设计,较好地克服了TCP/IP协议不能适应空间通信链路的难题,支持采用基于TCP/IP协议的商用货架(COTS)软、硬件产品,可明显降低空间站空间因特网服务系统建设与维护成本;二是研究解决了涉及空间站测控通信网运行安全和空间信息安全的空间通信链路设计技术,空间站在同一条空间通信链路同时传输空间因特网数据和空间站测控通信数据,空间通信链路采用CCSDS的AOS协议,并通过建立虚拟的物理信道,解决了空间因特网数据和空间站测控通信数据的安全隔离问题,能满足空间站测控通信网运行安全和空间信息安全的要求。 相似文献

Has the current US space policy improved the USA's overall strategic position? Does it affect favorably international partnerships? These questions are examined in terms of security, political economy, and influence. In today's context, where there are more space players, more options, more potential for unintended consequences, and higher stakes, unilateral action is more limited in its effectiveness than in earlier times. Surveying current US space policy, it is not clear that data-driven, analytically based decisions are being made to affect positively national independence, innovation, market creation, and international perceptions of the USA as a trustworthy partner. More promising are the steps taken to bolster a predictable space operational environment and economic competitiveness. Ultimately, in order to achieve American excellence and leadership, a ‘closed loop’ on the policy system is needed, to gauge regularly and systematically whether the US is achieving the desired national outcomes. 相似文献

2005年8月9日,发现号航天飞机在执行完14天的太空飞行任务后,安全返回美国爱德华兹空军基地。此次飞行是哥伦比亚号航天飞机失事后的首次飞行。虽然在此前两年半的时间里美国航宇局(NASA)耗资30多亿美元,在六个方面改善了航天飞机的性能,但整个过程并不顺利,可谓一波三折,引起了全世界的广泛关注。让美国人引以自豪的航天飞机日显老态,逐渐暴露出诸多问题,这对美国今后的航天事业也将产生深远的影响。 相似文献

The envisaged future space research programmes, whether in the field of space exploration or Earth observation are becoming more and more technically complicated and so costly that a single nation can hardly afford to realize them. Major non-European space-faring nations, China and India will progressively play an important role besides US, Russia and Japan. The Space Advisory Group of the European Commission recommended that the European Commission supports within Horizon 2020 a comprehensive Robotic Mars-Exploration Programme under European leadership that should become an essential element of a coordinated international space research programme. The International Space Station (ISS) experience shows that cooperative space programmes build links between industries and laboratories from around the world, which then further develop in non-space related activities, with positive impact on the economy and scientific research. Strategies need to be developed to mitigate the gradual increasing risks incurred by climate change. In order to lower their entry barrier to engage in space emerging and developing space nations need to be included in cooperative space programmes. We present the recommendations of the Space Advisory Group of the European Commission concerning Europe's participation to global space endeavours. 相似文献
