Roman Krawec 《Space Policy》1995,11(2)
Following Ukraine's 1991 declaration of independence and the disintegration of the USSR, Ukraine inherited a third of the Soviet Union's space industry. This paper presents an overview of the main features of Ukraine's current policy on the exploitation of this capability as a factor in the transformation of its economy. It illustrates how the policy is being realized in the areas of launch systems, Earth observation, satellite communications and international relations, and concludes that Ukraine's strengths in the space field are counterbalanced by obstacles which must be faced, both within the country and externally. 相似文献

According to the UK government, the announcement in July 1987 of a freeze on the British National Space Centre's (BNSC) budget was based solely on lack of money and the belief that private industry, rather than the state, should fund space activities. In challenging the validity of this view, the author suggests that it has also been used to conceal internal bureaucratic competition and a myopic, market-driven mind-set. 相似文献

Scientific and policy developments in the field of Near-Earth Objects (NEOs) since the UN NEO conference in 1995 are briefly outlined. Some areas of research and discovery have exhibited considerable progress while others have languished. In particular, facilities in the southern hemisphere for discovery and tracking of NEOs are inadequate. Suggestions are made both at the scientific and technical levels as well as at the policy level to provide coordinated and coherent progress in developing a long-term approach to NEO hazard mitigation. The next step should be the establishment of a panel of international scientific experts on the subject. 相似文献

As planetary exploration advances, the likelihood of encountering suspected artifacts of astrobiological activity increases, which, it is argued, should be investigated under the auspices of proto-scientific xenoarchaeology. Considering both the unfavorable conditions under which such an investigation may be undertaken (e.g., while observing international planetary protection protocols, utilizing remote sensing techniques in exotic pressure, temperature, chemical, and gravity environments, or adhering to stringent terrestrial biological quarantine and security measures) as well as the demonstrated propensity of the social mind to romanticize or mythologize even the most benign planetary landforms, it is clear that a reactive and poorly preconceived xenoarchaeological methodology will be plagued by inaccuracies, rushed judgments, unrealized bias, misinformation, and erroneous conclusions, along with the negative socio-political impacts that accompany them. Central principles for establishing a rigorous xenoarchaeological methodology are proposed, scientific and technical difficulties are discussed, pertinent international protocols and agreements are reviewed, and sociological and historical considerations are explored. 相似文献

One of the most important developers of liquid propellant rocket engines in Argentina was Polish-born Ricardo Dyrgalla. Dyrgalla immigrated to Argentina from the United Kingdom in 1946, where he had been studying German weapons development at the end of the Second World War. A trained pilot and aeronautical engineer, he understood the intricacies of rocket propulsion and was eager to find practical applications to his recently gained knowledge.Dyrgalla arrived in Argentina during Juan Perón's first presidency, a time when technicians from all over Europe were being recruited to work in various projects for the recently created Argentine Air Force.Shortly after immigrating, Dyrgalla proposed to develop an advanced air-launched weapon, the Tábano, based on a rocket engine of his design, the AN-1. After a successful development program, the Tábano was tested between 1949 and 1951; however, the project was canceled by the government shortly after. Today, the AN-1 rocket engine is recognized as the first liquid propellant rocket to be developed in South America. Besides the AN-1, Dyrgalla also developed several other rockets systems in Argentina, including the PROSON, a solid-propellant rocket launcher developed by the Argentine Institute of Science and Technology for the Armed Forces (CITEFA). In the late 1960s, Dyrgalla and his family relocated to Brazil due mostly to the lack of continuation of rocket development in Argentina. There, he worked for the Institute of Aerospace Technology (ITA) until his untimely death in 1970. Ricardo Dyrgalla deserves to be recognized among the world's rocket pioneers and his contribution to the science and engineering of rocketry deserves a special place in the history of South America's rocketry and space flight advocacy programs. 相似文献

Discussions of space security tend to recurrently return to the vexed issue of the ‘militarization’ and ‘weaponization’ of outer space. Debate over whether or not a sustainable definition can be maintained between these two concepts has been a feature of both academic and policy discourses, and has been particularly contentious with regard to new proposals for arms control in outer space. Yet, this paper argues, the militarization/weaponization debate fails to capture to vagaries of contemporary space policy with regard to understandings of ‘security’, and is in this sense an insufficient way of approaching the subject of space security in the first instance. Instead it is now more accurate to say that outer space is becoming ever more ‘securitized’: that is, access to space is now commonly framed as crucial to the military, economic and environmental security of leading states and international organizations. 相似文献

The discoveries and knowledge gained from space exploration and technology development are valuable scientific education tools which are not being adequately used in the classroom. Moreover, the increasing application of space technology to everyday life and industry requires a work force educated to be able to work productively in this field and to take advantage of all it has to offer. This article provides a survey of what is presently being done in the field of space education in Europe and the USA. Although encouraging, it is not nearly enough to meet the needs of 21st century society, principally because current efforts lack government or industry support. The author argues that this state of affairs must change, and proposed an international symposium as a first step towards this goal. 相似文献

In 1989, the two sub-committees of the UN Committee on the Peaceful Uses of Outer Space (COPUOS) - the Scientific and Technical Sub-Committee and the Legal Sub-Committee - held their 26th and 28th sessions, respectively, at UN Headquarters in New York. They subsequently produced reports which were discussed at the 33rd session of COPUOS in New York from 5 to 15 June 1989. N. Jasentuliyana, Director of the Outer Space Affairs Division at the UN, discusses their work. 相似文献

As the most successful dual-use technology at present the Global Navigation Satellite System (GNSS) also has extensive recognition in China. China began developing navigation satellites in 1967 and now has 45 years' experience in the field. 2012 was a crucial year for China's GNSS: the first-stage project of the second-generation global navigation satellite system was rounded off, and it entered service for regional area navigation and positioning. This paper discusses the development history of China's satellite navigation, analyzes the background to China's decision to develop an independent GNSS and investigates the formation of its three-step development strategy. It reviews the system construction and industrial policy of the BeiDou system and the actions taken by various government departments at different times. 相似文献

Because of the physical scale of human operations at present, we need to extend them into the Solar System for sustainability and into interstellar space for knowledge. Stabilizing the population on Earth, as well as reducing poverty, is vital, as is a more environmentally appropriate demographic transition than the historical one. Space assets can contribute most to strategic threats in areas like power and minerals and can also assist global education. Such public interest is important as education, but it is vital to remember that a certain level of precision in materials and engineering is needed before ideas become realizable. The crucial step is to turn the space environment to an open market and override the present government monopoly constraint. As a start, a Center for International Space Industrialization Research (CSIR) is to be set up as a model for the better understanding of the issues involved, thus making a case for strategic investment for space assets. 相似文献

This paper presents the review of results of the navigating experiments which have been carried out during flight of microgravitational space platform (MSP) Foton-M2 in May–June 2005. The brief characteristic of the created MIRAGE–M equipment consisting from magnitometric system and satellite radionavigation receiver is given. The measurements have allowed to restore unguided MSP movement and to estimate a level of microaccelerations (microgravitations) onboard during flight, and have provided precision time-position binding of the research experiments. The data from the equipments transmitted on the telemetering channel have allowed testing the information technologies of virtual support of experiments in space. Flight testing of the equipment has allowed make a conclusion on usefulness of accommodation onboard the small-sized auxiliary navigating system focused for work with users of research experiments. The experiments on MSP Foton-M2 are the development of experiments with MIRAGE equipment carried out in 1999 during flight time of MSP Foton-12 [N.D. Semkin, V.V. Ivanov, V.I. Abrushkin, V.L.

This paper investigates the role of the European Parliament (EP) in the development of the space policy of the EU (EUSP), an important policy area that has been neglected in the political science and EU studies literature. EUSP is the offspring of the European space policy which started as a purely intergovernmental affair, but gradually acquired a supranational dimension. Although the EP did little to initiate this process, it always supported the involvement of the EU in space, and it used both its formal and informal powers to affect and promote its development. Under the consultation procedure the EP managed to become a conditional agenda setter, and under co-decision an influential legislation maker. The changes it introduced in the European global navigation satellite and Earth observation programmes relate not only to the inter-institutional balance and its controlling powers, but to a series of substantive issues also. Consequently, the activism of the EP has played an important part in the development of the EUSP, even if it was not the main force behind its inception. 相似文献
