It was the first module to be sent into orbit by the company, and is testing various systems, materials and techniques related to determining the viability of long-term inflatable space structures. Such structures, including this module and others built by Bigelow Aerospace, are based on the NASA TransHab design, which provides increased interior volume at a reduced launch diameter and potentially reduced mass compared to traditional rigid structures. == Spacecraft history == ''Genesis I'' was launched on 12 July 2006 at 14:53:30 UTC aboard an ISC Kosmotras Dnepr rocket, launched from Dombarovskiy missile base near Yasniy, Russia. Spacecraft control was transferred to Bigelow Aerospace at 15:08 UTC after a successful orbital insertion.〔 Designed as a one-third scale model of the full size ''BA 330'', when in orbit the main body of the craft measures long and in diameter, with an interior habitable volume of . As part of the expandable design, however, the module launched with a diameter of only , inflating to its full size after entering orbit.〔 The expansion process took approximately ten minutes.〔 ''Genesis I'' suffered a major radiation event in December 2006 as a result of a "solar storm". Mission controllers were able to restart the system in time, though the situation was described as being "one fault away from the spacecraft being dead." Despite this, no lasting damage appears to have occurred and the spacecraft was operating in "excellent shape" .〔 The spacecraft completed its 10,000th orbit on 8 May 2008, some 660 days after launch. By that time, ''Genesis I'' had traveled more than 430 million kilometers (270 million miles), the equivalent of going to the Moon and back 1,154 times, and had taken more than 14,000 images, including images of all seven continents. Its electrical equipment had been continuously powered since it first became operational.〔 Although the design life of the spacecraft avionics was only six months, the avionics systems worked flawlessly for "over two and a half years" before failure. The data received after the first six months was a re-verification of the validation test suite that was accomplished during the design life period.〔 In February 2011, Bigelow reported that the vehicle had "performed flawlessly in terms of pressure maintenance and thermal control-environmental containment."〔 The orbital life was originally estimated to be 12 years, with a gradually decaying orbit resulting in re-entry into Earth's atmosphere and burn-up expected. , the vehicle remains in orbit.〔 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「Genesis I」の詳細全文を読む スポンサード リンク
