The BA 330 (previously known as the Nautilus space complex module) is an inflatable space habitat privately manufactured by Bigelow Aerospace. The design was evolved from NASA's TransHab habitat concept. BA 330 will have of internal space, hence its numeric designation. The craft will 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. Bigelow indicated that the habitat could be launch-ready by 2017.〔 == Features == Compared to their own weight, expandable modules offer more living space than traditional rigid modules. For example, the pressurised volume of a 20-ton BA 330 module is 330 m3, compared to 106 m3 of the 15 ton ISS Destiny module. Thus BA 330 offers 210% more habitable space, with an increase of only 33% in mass. Bigelow also claims that the module provides radiation protection equivalent to, and ballistic protection superior to, the International Space Station.〔(Bigelow Aerospace — Next-Generation Commercial Space Stations: BA 330 ), Bigelow Aerospace, 2010, accessed 29 December 2010. (())〕 The exterior of the craft is intended to be long by in diameter and the module will weigh between and . The habitat is designed to have two solar arrays and two thermal radiator arrays for heat dissipation, as well as life support systems to sustain a crew of up to six astronauts. It will also have "a zero-g toilet with solid and liquid waste collection, semi-private berths for each crew member, exercise equipment, a food storage and preparation station, ... lighting, and a personal hygiene station."〔 The wall thickness will be approximately when the module is fully expanded. The walls are made up of 24 to 36 layers for ballistic protection, thermal protection and radiation protection and will be as hard as concrete once the craft is fully expanded. The exterior will also feature four large windows coated with a UV protection film. Dual-redundant control thruster systems are to be used, one using mono-propellant hydrazine and the other using gaseous hydrogen and gaseous oxygen. The latter system is refillable from the on-board environmental control system.〔 Module-specific avionics will be provided for navigation, re-boost, docking and other on-orbit maneuvering. Bigelow Aerospace is developing the BA 330 module to mate with other spacecraft. In early illustrations, this was shown as being with the Russian Soyuz spacecraft, but it could theoretically be with any number of other vehicles. The module's large size is particularly beneficial for lunar astronauts or the crews of other long-duration space missions,〔 (Private Spaceflight Goes Public ), Alan Boyle, ''MSNBC Cosmic Log'', 1 February 2010.〕 which until now have been restricted to fairly cramped quarters for the several-day flight. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「BA 330」の詳細全文を読む スポンサード リンク
