私人太空飞船获批准可以开始全面生产!

美国国务院国际信息局《美国参考》karin从华盛顿报道,美国内华达山脉公司(SNC)已获得美国国家航空航天局(NASA)的批准,将开始全面生产其“追梦者”货运飞船。

该公司12月18日宣布,它完成了商业再供应服务(CRS) 2合同的一个里程碑,该合同被称为集成评审4。有了这一里程碑式的进展,该公司获准进入将向空间站运送货物的追梦车组装阶段。该公司CRS-2项目主管约翰·柯里(John Curry)在一份宣布这一里程碑的声明中表示:美国国家航空航天局(NASA)承认,SNC已经完成了这一关键里程碑,并批准了第一艘追梦飞船的全面生产,这是一个重大迹象,表明我们正沿着正确的道路,为该行业增加至关重要的科学回报。

与SpaceX和Orbital ATK(现在的诺斯罗普·格鲁曼创新系统公司)一起,SNC是2016年1月从NASA获得CRS-2合同的三家公司之一。根据合同规定,每个公司至少有6个国际空间站的任务。为了执行这些任务,SNC提出了一种货运版本的追梦飞船,这是它为NASA的商业宇航员计划而开发。2014年美国国家航空航天局(NASA)将合同授予波音(Boeing)和SpaceX时,并没有选择这款飞行器,但SNC采用了可折叠机翼的设计,使其能够适应许多现有的有效载荷整流罩和一个货运模块。虽然《追梦者》的许多元素已经在生产中,但这次审查确认了整体设计已经准备好进行全面组装和测试。

SNC的共同所有人和首席执行官Fatih Ozmen在一份声明中说:IR4是经过多年的设计工作、分析和开发测试之后的一系列评审、文档和数据交付,这一全面审查批准了将追梦者项目推进到生产阶段,这样我们就可以把追梦者作为一个关键的空间站补给航天器尽快推向市场。“追梦者”的货运版本可以携带多达5500公斤的货物到国际空间站,并在跑道着陆时将1850公斤的货物送回地球。货物舱在返回时烧毁,可以处理额外的3400公斤货物。第一次发射是在联合发射联盟阿特拉斯5号上进行,计划不早于2020年年底,这个日期将取决于国际空间站的车辆发展状况和货物需求。

不过SNC仍在为未来的追梦任务保留发射选项,该公司负责太空探索系统的副总裁史蒂夫林赛(Steve Lindsey)在10月11日于新墨西哥州拉斯克鲁斯举行的个人和商业太空飞行国际研讨会上的一个小组讨论中说:我们正在研究所有的运载火箭。上市市场的竞争帮助SNC降低了成本,当运载火箭的价格下降时,这就打开了商业市场,运载火箭的价格大约是我们每次飞行任务成本的80%。这包括追梦软件的其他应用,比如自由飞行实验平台。在那次会议上,预计到明年10月,第一辆追梦飞船的组装和测试将“完成大部分工作,同时计划第二辆车的“改动和升级”。
