天舟一号货运飞船成功释放立方星

2017-08-02 07:27:52   央视网

原标题:天舟一号货运飞船成功释放立方星

8月1日15时03分,天舟一号货运飞船成功在轨释放一颗立方星,随即地面成功捕获立方星。本次试验是我国首次通过飞船系统采用在轨储存方式释放立方星,完成了非火工品装置的分离解锁技术、部署发射器与立方星间接口匹配技术以及部署发射器制造的材料和工艺保证技术验证,为后续我国空间站开展微纳卫星部署发射及在轨服务奠定了技术基础。

本次在轨释放的立方星为标准3U结构,安装在立方星在轨部署发射器内,于今年4月20日随天舟一号货运飞船发射升空,已在轨储存104天,该星的主要任务是开展相关航天新技术试验验证。(内容来源/航天技术试验项目办公室)

“天舟一号”发射:解决了一个世界难题

据《环球科学》4月21日报道,“天舟一号”不仅要为空间站运送物资,还承担了一些重要的科学实验任务。

如果说中国航天人的征途是“星辰大海”,那么“天舟一号”就是“星辰大海”中的生命之舟。天舟一号货运飞船,由中国空间技术研究院(中国航天科技集团五院)研制的一款货运飞船,也是中国首个货运飞船。在1992我国确定的载人航天“三步走”的发展战略中,发射载人飞船为第一步,突破航天员出舱活动技术、空间飞行器的交会对接技术,发射空间实验室为第二步,在第二步中同时要解决有一定规模的、短期有人照料的空间应用问题,为第三步建造空间站做准备。天舟一号的成功发射,将是我国载人航天工程“三步走”战略计划“第二步”的收官之作。

作为货运飞船,天舟一号的首要任务就是运输航天员所需的生活工作必需品,以及空间站所需的推进剂等。它庞大的身躯(长10.6m,宽3.35m)以及两舱结构设计(货物仓和推进舱)最大限度地满足了货物装载、提供能源、控制动力等需求。天舟一号在近地轨道上的运载能力为6.5吨左右,高于俄罗斯联邦航天局研制的进步号M型(2.5吨)以及日本宇宙航空研究开发机构的H-II运载飞船(6.0吨)。但是,如果你认为天舟一号仅仅是“太空货物的搬运工”那就大错特错了,天舟一号还有以下几个非常重要的任务。
