Expandable Space Habitat
Inflatable habitats or expandable habitats are pressurized tent-like structures capable of supporting life in outer space whose internal volume increases after launch. They have frequently been proposed for use in space applications to provide a greater volume of living space for a given mass. The first formal design and manufacture of an inflatable space habitat was in 1961 with a space station design produced by Goodyear (although this design was never flown). A proposal released in 1989 by Johnson Space Center's Man Systems Division outlined a diameter spherical habitat lunar outpost which was partially buried in the lunar surface. An inflatable module called TransHab (a portmanteau of ''Trans Habitation'') was proposed for the International Space Station, and later the private company Bigelow Aerospace revived the design for use in a number of potential civil and commercial applications. Construction The construction of an inflatable space habitat is determined by it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inflatable Station Concept - GPN-2003-00106
An inflatable is an object that can be inflated with a gas, usually with air, but hydrogen, helium and nitrogen are also used. One of several advantages of an inflatable is that it can be stored in a small space when not inflated, since inflatables depend on the presence of a gas to maintain their size and shape. Function fulfillment per mass used compared with non-inflatable strategies is a key advantage. Stadium cushions, impact guards, vehicle wheel inner tubes, emergency air bags, and inflatable space habitats employ the inflatable principle. Inflation occurs through several strategies: pumps, ram-air, blowing, and suction. Although the term ''inflatable'' can refer to any type of inflatable object, the term is often used in boating to specifically refer to inflatable boats. Types High-pressure vs. low-pressure A distinction is made between high-pressure and low-pressure inflatables. In a high-pressure inflatable, structural limbs like pillars and arches are built out o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vacuum
A vacuum is a space devoid of matter. The word is derived from the Latin adjective ''vacuus'' for "vacant" or "void". An approximation to such vacuum is a region with a gaseous pressure much less than atmospheric pressure. Physicists often discuss ideal test results that would occur in a ''perfect'' vacuum, which they sometimes simply call "vacuum" or free space, and use the term partial vacuum to refer to an actual imperfect vacuum as one might have in a laboratory or in space. In engineering and applied physics on the other hand, vacuum refers to any space in which the pressure is considerably lower than atmospheric pressure. The Latin term ''in vacuo'' is used to describe an object that is surrounded by a vacuum. The ''quality'' of a partial vacuum refers to how closely it approaches a perfect vacuum. Other things equal, lower gas pressure means higher-quality vacuum. For example, a typical vacuum cleaner produces enough suction to reduce air pressure by around 20%. But hig ...

Sovereign State
A sovereign state or sovereign country, is a polity, political entity represented by one central government that has supreme legitimate authority over territory. International law defines sovereign states as having a permanent population, defined territory (see territorial disputes), one government, and the capacity to enter into International relations, relations with other sovereign states. It is also normally understood that a Sovereignty#Sovereignty and independence, sovereign state is independent. According to the declarative theory of statehood, a sovereign state can exist without being Diplomatic recognition, recognised by other sovereign states.Thomas D. Grant, ''The recognition of states: law and practice in debate and evolution'' (Westport, Connecticut: Praeger, 1999), chapter 1. List of states with limited recognition, Unrecognised states will often find it difficult to exercise full treaty-making powers or engage in Diplomacy, diplomatic relations with other sovereign ...

Aviation Week
''Aviation Week & Space Technology'', often abbreviated ''Aviation Week'' or ''AW&ST'', is the flagship magazine of the Aviation Week Network. The weekly magazine is available in print and online, reporting on the aerospace, defense and aviation industries, with a core focus on aerospace technology. It has a reputation for its contacts inside the United States military and industry organizations. ''Aviation Week'' was a favorite conduit for defense-related companies and labs to leak information to the public as part of their policy by press release efforts. This led to it being informally referred to "Aviation Leak and Space Mythology". History The magazine was first published in August 1916. Early editors Ladislas d'Orsy and Donald W. McIlhiney (1921 to 25) were Quiet Birdmen. Publisher (1927 to 29) Earl D. Osborn was also a Quiet Birdman. With the coming of the Space Age, the current title was adopted in 1960. Other titles the magazine has held include ''Aviation & Aircraft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
B330
The B330 (previously known as the Nautilus space complex module and BA 330) was an inflatable space habitat being privately developed by Bigelow Aerospace from 2010 until 2020. The design was evolved from NASA's TransHab habitat concept. B330 will have of internal volume, hence its numeric designation. The craft is intended to support zero-gravity research including scientific missions and manufacturing processes. Beyond its industrial and scientific purposes, however, it has potential as a destination for space tourism and a craft for missions destined for the Moon and Mars. Several test articles were built and tested in various conditions in ground test facilities, but no flight versions were built. Features Compared to their volume-mass ratio, expandable modules offer more living space than traditional rigid modules. For example, the pressurised volume of a B330 module is , compared to of the 15-tonne ISS Destiny module. Thus B330 offers 210% more habitable space, wit ...

Sundancer
''Sundancer'' was the proposed third prototype space habitat intended to be launched by Bigelow Aerospace—and the first human-rated expandable module based on TransHab technology acquired from NASA. It was to have been used to test and confirm systems used in the company's commercial space station efforts during the early 2010s, and if successful, would have formed the first piece of the proposed commercial space station. While ''Sundancer'' had been under construction at the Bigelow plant in North Las Vegas, Nevada, the company announced in July 2011 that ''Sundancer'' had been removed from their station evolution path, and that the B330 would become the first production module. Spacecraft history and future Upon its original announcement, ''Sundancer'' was intended to be the fourth module orbited by Bigelow Aerospace. In August 2007, however, it was announced that due to rising space launch costs and the level of success of the first two Bigelow modules launched, the third d ...

Bigelow Next-Generation Commercial Space Station
The Bigelow Next-Generation Commercial Space Station was a private orbital space station under conceptual development by Bigelow Aerospace in the 2000s and 2010s. Previous concepts of the space station had included multiple modules such as two B330 expandable spacecraft modules as well as a central docking node, propulsion, solar arrays, and attached crew capsules. However it was also suggested that each B330 can operate as an independent space station. Attaching a B330 to the International Space Station or flying a B330 alone have been suggested by Robert Bigelow. On 8 April 2016, NASA launched a Bigelow inflatable module and attached it to the ISS, where it has been tested for over four years. History Early work at Bigelow Aerospace on expandable space habitats, with plans to eventually assemble them into on-orbit space stations, began in the early years after the company was formed in 1999. By 2004, plans made public included assembly of multiple modules "into a manne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NASA
The National Aeronautics and Space Administration (NASA ) is an independent agency of the US federal government responsible for the civil space program, aeronautics research, and space research. NASA was established in 1958, succeeding the National Advisory Committee for Aeronautics (NACA), to give the U.S. space development effort a distinctly civilian orientation, emphasizing peaceful applications in space science. NASA has since led most American space exploration, including Project Mercury, Project Gemini, the 1968-1972 Apollo Moon landing missions, the Skylab space station, and the Space Shuttle. NASA supports the International Space Station and oversees the development of the Orion spacecraft and the Space Launch System for the crewed lunar Artemis program, Commercial Crew spacecraft, and the planned Lunar Gateway space station. The agency is also responsible for the Launch Services Program, which provides oversight of launch operations and countdown management f ...
