Virgin Galactic的太空船二号模型,主要由碳复合材料制成,目前联邦航天管理局(FAA)已为其动力测试飞行开了绿灯。该公司的飞船开发商Scaled Composites,已获得一个针对亚轨道商业飞船和白骑士二号运输机高空发射飞船的实验性发射许可。两年多来,Virgin Galactic一直致力于完善其第二代模型。尽管其他少数飞船也曾获得过发射许可,但多数是非载人的火箭,太空船二号是第一个获得发射许可的设计用于载人的航天飞行。
The Virgin Galactic spacecraft model II, made mainly of carbon composite materials, is currently the Federal Aviation Administration (FAA) which has given a green light to its power test flights. Scaled Composites, the company’s spacecraft developer, has obtained an experimental launch license for high altitude launch vehicles for sub-orbital commercial spacecraft and White Knight II. For more than two years, Virgin Galactic has been working on refining its second-generation model. Although most of the other few spacecraft were also licensed for launch, most were non-manned rockets, and SpaceShip II was the first spaceflight-designed spacecraft to be used for manned space missions.
