Space Colonization
Space colonization (or extraterrestrial colonization) is the human settlement, settlement or colonization of outer space and astronomical bodies. The concept in its broad sense has been applied to any permanent human presence in space, such as a space habitat or other extraterrestrial settlements. It may involve a process of occupation or control for exploitation, such as Space mining, extraterrestrial mining. Making territorial claims in space is prohibited by international space law, defining space as a Common heritage of humanity, common heritage. International space law has had the goal to prevent colonial claims and militarization of space, and has advocated the installation of international regimes to regulate access to and sharing of space, particularly for specific locations such as the limited space of Geostationary orbit#Orbital allocation, geostationary orbit or the Moon. To date, no permanent space settlement other than temporary Space habitat (facility), space ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Space And Survival
Space and survival is the idea that the long-term survival of the human species and technological civilization requires the building of a spacefaring civilization that utilizes the resources of outer space, and that not doing this might lead to human extinction. A related observation is that the window of opportunity for doing this may be limited due to the decreasing amount of surplus resources that will be available over time as a result of an ever-growing population. The earliest appearance of a connection between space exploration and human survival appears in Louis J. Halle, Jr.'s 1980 article in ''Foreign Affairs'', in which he stated colonization of space will keep humanity safe should global nuclear warfare occur. This idea has received more attention in recent years as advancing technology in the form of reusable launch vehicles and combination launch systems make affordable space travel more feasible. Risk to humanity Existential risk are risks of human extinction or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Falcon Heavy
Falcon Heavy is a super heavy-lift launch vehicle with partial reusability that can carry cargo into Earth orbit and beyond. It is designed, manufactured and launched by American aerospace company SpaceX. The rocket consists of a center core on which two Falcon 9 boosters are attached, and a second stage on top of the center core. Falcon Heavy has the second highest payload capacity of any currently operational launch vehicle behind NASA's Space Launch System (SLS), and the fourth-highest capacity of any rocket to reach orbit, trailing behind the Space Launch System, SLS, Energia (rocket), Energia and the Saturn V. SpaceX conducted Falcon Heavy test flight, Falcon Heavy's maiden launch on 6 February 2018, at 20:45 Coordinated Universal Time, UTC. As a Boilerplate (spaceflight), dummy payload, the rocket carried Elon Musk's Tesla Roadster, a Tesla Roadster belonging to SpaceX founder Elon Musk, with a mannequin dubbed "Starman" in the driver's seat. The second Falcon Heavy laun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Low Earth Orbit
A low Earth orbit (LEO) is an geocentric orbit, orbit around Earth with a orbital period, period of 128 minutes or less (making at least 11.25 orbits per day) and an orbital eccentricity, eccentricity less than 0.25. Most of the artificial objects in outer space are in LEO, peaking in number at an altitude around , while the farthest in LEO, before medium Earth orbit (MEO), have an altitude of 2,000 km, about one-third of the Earth radius, radius of Earth and near the beginning of the Van Allen radiation belt#Inner belt, inner Van Allen radiation belt. The term ''LEO region'' is used for the area of space below an altitude of (about one-third of Earth's radius). Objects in orbits that pass through this zone, even if they have an apogee further out or are sub-orbital spaceflight, sub-orbital, are carefully tracked since they present a collision risk to the many LEO satellites. No human spaceflights other than the lunar missions of the Apollo program (1968-1972) have gone beyond L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Controlled Ecological Life-support System
Controlled (or closed) ecological life-support systems (acronym CELSS) are self-supporting life support systems for space stations and colonies typically through controlled closed ecological systems, such as the BioHome, BIOS-3, Biosphere 2, Mars Desert Research Station, and Yuegong-1. Original concept CELSS was first pioneered by the Soviet Union during the famed "Space Race" in the 1950s–60s. Originated by Konstantin Tsiolkovsky and furthered by V.I. Vernadsky, the first forays into this science were the use of closed, uncrewed ecosystems, expanding into the research facility known as the BIOS-3. Then in 1965, crewed experiments began in the BIOS-3. Rationale Human presence in space, thus far, has been limited to the Earth–Moon system. Also, everything that astronauts would need in the way of life support (air, water, and food) has been brought with them. This may be feasible for short missions of spacecraft, but it is not the most viable solution when dealing with the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Effect Of Spaceflight On The Human Body
The effects of spaceflight on the human body are complex and largely harmful over both short and long term. Significant adverse effects of long-term weightlessness include muscle atrophy and deterioration of the skeleton ( spaceflight osteopenia). Other significant effects include a slowing of cardiovascular system functions, decreased production of red blood cells (space anemia), balance disorders, eyesight disorders and changes in the immune system. Additional symptoms include fluid redistribution (causing the " moon-face" appearance typical in pictures of astronauts experiencing weightlessness), loss of body mass, nasal congestion, sleep disturbance, and excess flatulence. A 2024 assessment noted that "well-known problems include bone loss, heightened cancer risk, vision impairment, weakened immune systems, and mental health issues... t what’s going on at a molecular level hasn’t always been clear", arousing concerns especially vis a vis private and commercial space ...

Monthly Review
The ''Monthly Review'' is an independent socialist magazine published monthly in New York City. Established in 1949, the publication is the longest continuously published socialist magazine in the United States. History Establishment Following the failure of the independent 1948 presidential campaign of Henry A. Wallace, two former supporters of the Wallace effort met at the farm in New Hampshire where one of them was living. The two men were literary scholar and Christian socialist F.O. "Matty" Matthiessen and Marxist economist Paul Sweezy, who were former colleagues at Harvard University. Matthiessen came into an inheritance after his father died in an automobile accident in California and had no pressing need for the money. Matthiessen made the offer to Sweezy to underwrite "that magazine weezyand Leo Huberman were always talking about," committing the sum of $5,000 per year for three years. Matthiessen's funds made the launch of ''Monthly Review'' possible, although th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Social Issue
A social issue is a problem that affects many people within a society. It is a group of common problems in present-day society that many people strive to solve. It is often the consequence of factors extending beyond an individual's control. Social issues are the source of conflicting opinions on the grounds of what is perceived as morally correct or incorrect personal life or interpersonal social life decisions. Social issues are distinguished from Economic policy, economic issues; however, some issues (such as immigration) have both social and economic aspects. Some issues do not fall into either category, such as warfare. Exemplary for social issues was the so-called social question in the beginning of the Industrial Revolution, industrial revolution. Growing poverty on one and growing population and Materialism, materialistic wealth on the other hand caused tension between very rich and poorest people inside society. There can be disagreements about what social issues are wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
