In January of 2007, China knocked one of its weather satellites out of orbit, and threw the international community into panic. Some figured the satellite-killer test was the harbinger of a future war in space that could cripple a technology-dependent United States military. This viewpoint examines the possibilities of a Chinese assault on American satellites.  相似文献

The loss of the Space Shuttle Columbia on 1 February 2003 brought to the fore the sad history of the Space Shuttle's origins, evolution, operation, and the continuing challenge of space access. The crisis that emerged in human access to space because of the accident was greater than any experienced since the end of the Apollo program more than thirty years earlier. This essay explores the origins and operations of the Space Shuttle, the varied efforts to build a successor vehicle versus upgrading the shuttle fleet, and suggests that the first decade of the twenty-first century promises to offer both serious challenges and enormous potential for the development of new launch vehicles that may finally achieve the long-held dream of reliable, affordable access to space. The essay ends by asking whether or not the half-hearted quest for a shuttle replacement might not portend the demise human spaceflight for the United States.  相似文献

This article follows the evolution of the relationship between the Russian space program and spirituality from an astrosociological perspective. It demonstrates that the Russian space program has its roots in Nikolai Fedorov's Cosmism, which envisaged the technological resurrection of the dead and space colonization, and in Marxism, which used space exploration as a means of proving atheism. Whereas the conquest of space has been perceived throughout the world in an ambivalent way, either as an act endorsed by Divinity or as a blasphemous feat, the Soviets took pride in reinventing the “Tower of Babel” in order to “make a name for themselves” and dethrone God (Genesis 11:4). Moreover, the technological miracles of spaceflight and the worship of Yuri Gagarin support the view that Soviet Communism was a state religion. After the fall of the Soviet Union, Orthodox Christianity brought its own contribution to the Russian space program. It will be also shown that, even during the Soviet period, appearances contrasted with the feelings of many of the cosmonauts.  相似文献

The space age is likely to be dominated by space commercial activities. As these activities develop, it is important to consider business values, commercial ethics, and trade discipline. The failure to do so could result in space commercial development on the basis of greed for profit and competitive advantage for advancement, as has taken place on Earth. To better prevent this possibility, this article proposes that there is the need to develop a “New Ethics for Space Commerce” based on high standards of business morality and commercial honesty, with moorings in conscious social responsibility and due regard to ecological sustainability.  相似文献

For 21st century warfare, space is the unquestioned new high ground for military operations. The United States (U.S.) has relied on satellites for significant support to military operations and activities since Desert Storm in 1991. Indeed, the U.S. enjoys an asymmetric advantage in modern warfare utilizing our space capabilities. States with interests hostile to the U.S. believe that the significant dependence on space assets by the U.S. military could become its “Achilles heel” in future combat operations. What are the legal and policy bases for the U.S. to respond to threats to space systems that provide support to our military forces? Should the U.S. rely on space arms control initiatives to ensure security in space? This Viewpoint analyzes the international space law regime and U.S. National Space Policy framework applicable to the conduct of military space operations and activities, including the use of force in space to protect and defend our satellite networks as well as our military forces.  相似文献

The United States (US) launch infrastructure is at a crisis point. Human access to space embodied in the Space Shuttle is due to be phased out by 2010. Currently, there are no heavy lift, 100 ton class launchers to support the US national vision for space exploration. Medium and large expendable launch providers, Boeing's Delta IV, and Lockheed-Martin's Atlas V Evolved Expendable Launch Vehicles are so expensive that the Delta no longer carries commercial payloads and the Atlas is unlikely to show significant growth without equally significant cost reductions and commercial traffic growth. This set of circumstances questions US dependence on these launch vehicles for national security purposes. High cost growth also exists with small launch vehicles, such as Pegasus, and the promising new field of small and microsatellites is little developed in the US, while foreign efforts, particularly European, are expanding largely on the availability of low-cost Russian boosters. One bright point is the emerging private sector, which is initially pursuing suborbital or small lift capabilities. Although such vehicles support very limited US Department of Defense or National Aeronautics and Space Administration spaceflight needs, they do offer potential technology demonstration stepping stones to more capable systems needed in the future of both agencies. This article outlines the issues and potential options for the US Government to address these serious shortcomings.  相似文献

The United States (U.S.) has deepening dependence on space systems for economic prosperity, civil government administration, priority science and exploration programs, and national security while at the same time there is dramatic growth in competitive space capabilities and demonstrated threats to space systems globally. Despite this, the U.S. has not invested sufficient resources to meet National policy direction for capabilities to insure freedom of action in space, especially space situational awareness capabilities—the cornerstone of deterrence from space attacks. A principle reason for this shortfall is the historical absence of an organization accountable for securing the space domain like those of land, sea, and air. Using the analogy of the Army Air Corps, the author recommends creation of an autonomous Space Corps realized out of existing organizations within the USAF. The AF Space Corps would manage a separate space budget and all space professionals in organizing, training, and equipping national security space capabilities including those necessary to secure the space domain for peaceful use.  相似文献

This article argues that what naval power was to the 17th century—knitting together separate trading systems and bridging new resources, wealth, mobility, and establishing an international system of trade that pulled various powers into the dominant power's orbit—space power can be for the 21st century. To this end, airmen must take a wider view of what strategic value the United States Air Force (USAF) can provide for the United States (U.S.) beyond support for warfighting.  相似文献

Space assets represent the most critical undefended resource of the United States. Though the government has clearly been aware of this weakness for over a generation, little appears to have been done about it. Every day these assets become more critical, and the threats against them are growing in kind. The United States must address these threats in order to prevent potential future issues in regard to military command and control, as well as the American way of life. This article not only outlines threats to space assets but proposes means by which U.S. space assets could be protected. Such protection comes not only from technology, which has been capable for years of doing the job, but from policy choice as well. In regard to policy, increasing research and development for space-based weapons, reevaluating existing treaties, and increasing interagency cooperation are all needed to better protect U.S. space assets.  相似文献

The influence of technology on the conduct of warfare and the development of strategy is still largely misunderstood. This confusion also holds true regarding technology's influence on space warfare and the development of space strategy. Judging from history, we can expect that advances in space-related technology will be used in ways commensurate with the current paradigm, especially with respect to military operations. Therefore, space operations will probably play supporting roles to operations on land, at sea, and in the air, at least in the near term. It will likely be some time until the strategic advantages of space-based or space-enabled operations are fully appreciated and effectively employed. Additionally, the historical theory and principles of general warfare remain valid, even when considering military operations in space. While advances in space-related technology or space-based weaponry will not change the fundamental nature of warfare, they are expected to change warfare's conduct and character. Through a better understanding of technology's influence on military operations, it is possible to develop a more complete theory and more fully developed strategic principles of space warfare.  相似文献

This paper uses case-study material from a local urban park in Glasgow, Scotland, to reflect on some aspects of the wider politics of culture led urban regeneration in relation to community involvement and participation and its relationship with public space. Using case-study material from before, during and after the park's development, it highlights how the initial discursive and policy practices utilised by the city and the park's designer served to create an illusion of collaboration and inclusive public space and that the park's development in the long term was starkly revealed to be primarily focused on improving Glasgow's wider image and improving Glasgow's attractiveness to potential inward investors. It will be shown, then, that the inclusive language surrounding culture-led regeneration as regards this urban public space was obfuscatory and that the underlying social context and local public space needs were undermined by wider economic goals.  相似文献

abstract This article asks whether the rising number of women in the paid labor force over the last half-century has been accompanied by a parallel trend of increased recognition of a breadwinning status for women, or if traditional role conceptions have persisted in spite of women's changed economic and social circumstances. I theorize that employer-provided benefits are a unique form of compensation that, by helping parents balance work and family, directly affect parents in their capacities as breadwinners. As such, assessing women's and men's access to these benefits over the period of women's rising labor force participation can be very revealing of the acceptance of women as breadwinners. To acquire a general picture of women's and men's access to employer-provided benefits, I compare access to benefits from 1940 to 1990 in a modal women's occupation ("professional nurses") to a modal men's occupation ("automobile mechanics and repairmen"). Through the studied time span, these occupations are the largest comparably sized women's and men's occupations that are also similar in pay level and extent of unionization. This allows me to control for pay level and unionization, important alternative explanations for women's restricted access to benefits. I hypothesize that nurses have had more restricted access to employer-provided benefits than have auto mechanics. I find a disadvantage for nurses relative to auto mechanics through most of the time period, which nonetheless diminishes and then reverses slightly at the end. Taking into consideration subtleties, as well as patterns masked in the data as presented, these findings suggest at best a rather slow rate of acceptance of a breadwinning status for women, and at worst, a continuation of traditional gender norms.  相似文献

With the introduction and development of space techniques, three types of remote reality, or tele-reality, have emerged: (1) the Earth, its environments, and its inhabitants have been brought closer to each of us; (2) the planets in the solar system are now “at hand's reach”—a robotic hand, that is; and (3) deep space is brought to our screens in three dimensions. But remote reality raises questions: What connection does it make between the perceptible and the intelligible; and what confusion does it maintain between what is real and what appears on the screen? New practices are challenging the way we handle the relationship between seeing, knowledge, and power, and questioning our ethical values. It is time and essential that we redefine the conditions and boundaries of our “tele-techniques.”  相似文献
