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 ...

Bigelow Aerospace
Bigelow Aerospace is an American aeronautics and outer space technology company which manufactures and develops expandable space station modules. Bigelow Aerospace was founded by Robert Bigelow in 1998, and is based in North Las Vegas, Nevada. It is funded in large part by the profit Bigelow gained through his ownership of the hotel chain, Budget Suites of America. By 2013, Bigelow had invested US$250 million in the company. Bigelow stated on a number of occasions that he was prepared to fund Bigelow Aerospace with about US$500 million through 2015 in order to achieve launch of full-scale hardware. Bigelow Aerospace announced in 2010 that they intended to create a modular set of space habitats for creating or expanding space stations but despite many concepts and models, never completed a working space station beyond two small prototypes that flew in 2006 and 2007. In March 2020, the company laid off all 88 of its employees due to the COVID-19 pandemic, and planned to rehir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bigelow 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] |
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, wi ...

Galaxy (spacecraft)
''Galaxy'' (previously ''Guardian'') was a canceled prototype space habitat designed by the American firm Bigelow Aerospace, and was intended to be the third spacecraft launched by the company in their efforts to create a commercial space station. Like other modules made by Bigelow Aerospace, ''Galaxy'' was based on the inflatable TransHab design by NASA, and was to be used for advanced systems testing before the company launched human-rated vehicles. Spacecraft history ''Galaxy'' started life as twin spacecraft named ''Guardian'' which would have acted as 45% scale intermediates between the one-third size ''Genesis I'' & '' Genesis II'' pathfinders and the full size ''BA 330'' man-rated module. Sometime after 2004, the two ''Guardian'' flights were split into the ''Galaxy'' module and larger ''Sundancer'' module, each testing progressively advanced systems. This ''Galaxy'' had twice the interior volume of the ''Genesis'' craft: . In 2007, the parameters for ''Galaxy'' were aga ...

Genesis II (space Habitat)
''Genesis II'' is the second experimental space habitat designed and built by the private American firm Bigelow Aerospace, launched in 2007. As the second module sent into orbit by the company, this spacecraft builds on the data and experience gleaned from its previously orbited sister-ship ''Genesis I''. Like its sister-ship and other modules being designed by Bigelow Aerospace, this spacecraft is based on the NASA TransHab design, which provides increased interior volume and reduced launch diameter along with potentially reduced mass compared to traditional rigid structures. ''Genesis II'' was "retired" when its avionics systems stopped working after two and a half years, thus becoming a derelict spacecraft. , the spacecraft remains in orbit. Spacecraft history Similar to the process endured by Bigelow for ''Genesis I'', transporting ''Genesis II'' to Russia for launch was the end result of nearly a year of regulatory processes due to restrictions imposed by Interna ...

Degree (angle)
A degree (in full, a degree of arc, arc degree, or arcdegree), usually denoted by ° (the degree symbol), is a measurement of a plane angle in which one full rotation is 360 degrees. It is not an SI unit—the SI unit of angular measure is the radian—but it is mentioned in the SI brochure as an accepted unit. Because a full rotation equals 2 radians, one degree is equivalent to radians. History The original motivation for choosing the degree as a unit of rotations and angles is unknown. One theory states that it is related to the fact that 360 is approximately the number of days in a year. Ancient astronomers noticed that the sun, which follows through the ecliptic path over the course of the year, seems to advance in its path by approximately one degree each day. Some ancient calendars, such as the Persian calendar and the Babylonian calendar, used 360 days for a year. The use of a calendar with 360 days may be related to the use of sexagesimal numbers.
