Space Sustainability
Space sustainability aims to maintain the safety and health of the space environment, as well as planetary environments. Similar to sustainability initiatives on Earth, space sustainability seeks to use the environment of space to meet the current needs of society without compromising the needs of future generations. It usually focuses on space closest to Earth, Low Earth Orbit (LEO), since this environment is the one most used and therefore most relevant to humans. It also considers Geostationary Equatorial Orbit (GEO) as this orbit is another popular choice for Earth-orbiting mission designs. The issue of space sustainability is a new phenomenon that is gaining more attention in recent years as the launching of satellites and other space objects has increased. These launches have resulted in more space debris orbiting Earth, hindering the ability of nations to operate in the space environment while increasing the risk of a future launch-related accident that could disrupt its p ...

Space Sustainability Overview Black
Space is a Three-dimensional space, three-dimensional continuum containing position (geometry), positions and direction (geometry), directions. In classical physics, physical space is often conceived in three linear dimensions. Modern physicists usually consider it, with time, to be part of a boundless four-dimensional Continuum (theory), continuum known as ''spacetime''. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework. In the 19th and 20th centuries mathematicians began to examine geometries that are Non-Euclidean geometry, non-Euclidean, in which space is conceived as ''space curvature, curved'', rather than ''flat space, flat'', as in the Euclidean space. According to Albert Einstein's theory of general relativity, space around gravitational fields deviate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Outer Space Treaty
The Outer Space Treaty, formally the Treaty on Principles Governing the Activities of States in the Exploration and Use of Outer Space, including the Moon and Other Celestial Bodies, is a Multilateralism, multilateral treaty that forms the basis of international space law. Negotiated and drafted under the auspices of the United Nations Security Council, United Nations, it was opened for signature in the United States, the United Kingdom, and the Soviet Union on 27 January 1967, entering into force on 10 October 1967. , 116 countries are parties to the treaty—including all major space-faring nations, spacefaring nations—and another 22 are signatories. The Outer Space Treaty was spurred by the development of intercontinental ballistic missiles (ICBMs) in the 1950s, which could reach targets through outer space. The Soviet Union's launch of Sputnik 1, Sputnik, the first artificial satellite, in October 1957, followed by a subsequent arms race with the United States, hastened p ...

Environmental Regulations
Environmental laws are laws that protect the environment. The term "environmental law" encompasses treaties, statutes, regulations, conventions, and policies designed to protect the natural environment and manage the impact of human activities on ecosystems and natural resources, such as forests, minerals, or fisheries. It addresses issues such as pollution control, resource conservation, biodiversity protection, climate change mitigation, and sustainable development. As part of both national and international legal frameworks, environmental law seeks to balance environmental preservation with economic and social needs, often through regulatory mechanisms, enforcement measures, and incentives for compliance. The field emerged prominently in the mid-20th century as industrialization and environmental degradation spurred global awareness, culminating in landmark agreements like the 1972 Stockholm Conference and the 1992 Rio Declaration. Key principles include the precautionary ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Space Law
Space law is the body of law governing space-related activities, encompassing both international and domestic agreements, rules, and principles. Parameters of space law include space exploration, liability for damage, weapons use, rescue efforts, Environmentalism, environmental preservation, information sharing, new technologies, and ethics. Other fields of law, such as administrative law, intellectual property law, arms control, arms control law, insurance law, environmental law, criminal law, and commercial law, are also integrated within space law. The origins of space law date back to 1919, with international law recognizing each country's sovereignty over the airspace directly above their territory, later reinforced at the Chicago Convention on International Civil Aviation, Chicago Convention in 1944. The onset of domestic space programs during the Cold War propelled the official creation of international space policy (i.e., the International Geophysical Year) initiated by t ...

Global Commons
Global commons is a concept to describe international, supranational, and global resource domains in which common-pool resources are found. They are "areas that lie outside of the political reach of any one nation State". Global commons include the earth's shared natural resources, such as the high seas (international waters), the atmosphere and outer space and the Antarctic in particular. The global commons concept investigates how those shared resources that lie outside of national borders can be managed or governed. Definition and usage "Global commons" is a term typically used to describe international, supranational, and global resource domains in which common-pool resources are found. In economics, common goods are rivalrous and non-excludable, constituting one of the four main types of goods. A common-pool resource, also called a common property resource, is a special case of a common good (or public good) whose size or characteristics makes it costly, but not impossibl ...

Orbital Spaceflight
An orbital spaceflight (or orbital flight) is a spaceflight in which a spacecraft is placed on a trajectory where it could remain in space for at least one orbit. To do this around the Earth, it must be on a free trajectory which has an altitude at perigee (altitude at closest approach) around ; this is the boundary of space as defined by NASA, the US Air Force and the FAA. To remain in orbit at this altitude requires an orbital speed of ~7.8 km/s. Orbital speed is slower for higher orbits, but attaining them requires greater delta-v. The Fédération Aéronautique Internationale has established the Kármán line at an altitude of as a working definition for the boundary between aeronautics and astronautics. This is used because at an altitude of about , as Theodore von Kármán calculated, a vehicle would have to travel faster than orbital velocity to derive sufficient aerodynamic lift from the atmosphere to support itself. Due to atmospheric drag, the lowes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Externality
In economics, an externality is an Indirect costs, indirect cost (external cost) or indirect benefit (external benefit) to an uninvolved third party that arises as an effect of another party's (or parties') activity. Externalities can be considered as unpriced components that are involved in either consumer or producer consumption. Air pollution from motor vehicles is one example. The Air pollution#Health effects, cost of air pollution to society is not paid by either the producers or users of motorized transport. Water pollution from mills and factories are another example. All (water) consumers are made worse off by pollution but are not compensated by the market for this damage. The concept of externality was first developed by Alfred Marshall in the 1890s and achieved broader attention in the works of economist Arthur Cecil Pigou, Arthur Pigou in the 1920s. The prototypical example of a negative externality is environmental pollution. Pigou argued that a tax, equal to the m ...

Space Liability Convention
The Convention on International Liability for Damage Caused by Space Objects, also known as the Space Liability Convention, is a treaty from 1972 that expands on the liability rules created in the Outer Space Treaty of 1967. In 1978, the crash of the nuclear-powered Soviet satellite Kosmos 954 in Canadian territory led to the only claim filed under the convention. Status The Liability Convention was concluded and opened for signature on 29 March 1972. It entered into force on 1 September 1972. As of 1 January 2021, 98 States have ratified the Liability Convention, 19 have signed but not ratified and four international intergovernmental organizations (the European Space Agency, the European Organisation for the Exploitation of Meteorological Satellites, the Intersputnik International Organization of Space Communications, and the European Telecommunications Satellite Organization) have declared their acceptance of the rights and obligations provided for in the Agreement.

Committee On Space Research
The Committee on Space Research (COSPAR) was established on October 3, 1958 by the International Council for Scientific Unions (ICSU) and its first chair was Hildegard Korf Kallmann-Bijl. Among COSPAR's objectives are the promotion of scientific research in space on an international level, with emphasis on the free exchange of results, information, and opinions, and providing a forum, open to all scientists, for the discussion of problems that may affect space research. These objectives are achieved through the organization of symposia, publication, and other means. COSPAR has created a number of research programmes on different topics, a few in cooperation with other scientific Unions. The long-term project COSPAR international reference atmosphere started in 1960; since then it has produced several editions of the high-atmosphere code CIRA. The code "IRI" of the URSI-COSPAR working group on the International Reference Ionosphere was first edited in 1978 and is yearly upda ...
