原标题:我国将在2022年前后建成近地载人空间站
2017年4月28日(星期五)上午10时,国新办在国务院新闻办新闻发布厅举行新闻发布会,请中国载人航天工程办公室主任王兆耀、中国航天科技集团公司副总经理杨保华、中国载人航天工程空间应用系统总设计师赵光恒、北京航天飞行控制中心副主任孙军介绍空间实验室飞行任务有关情况,并答记者问。
问:天舟一号任务之后,中国将正式迈进空间站建造阶段。请问中国空间站有哪些特色和亮点?目前空间站的研制进展情况如何?
中国载人航天工程办公室主任王兆耀:根据中央批准的方案,我国空间站阶段的主要任务是:在2022年前后,建成和运营我国近地载人空间站,掌握近地空间长期载人飞行技术,具备长期开展近地空间有人参与科学实验、技术试验和综合开发利用太空资源能力。
中国空间站将是我国长期在轨稳定运行的国家太空实验室,彰显出中国人自主发展载人航天事业的决心和才智,体现出中国在世界载人航天领域不可或缺的地位,成为全球华人中国梦航天梦的重要载体。目前形成的空间站方案具有鲜明的中国特色和时代特征。一是规模适度,具备拓展能力。预留了舱段和舱外载荷平台扩展能力,最大可扩展3个舱段。二是优化总体方案,增强建造灵活性和可靠性。采用转位机构和机械臂结合,进行舱段转移、对接,采用型谱化货船,在航天员和机械臂协同下,完成复杂舱外建造和操作活动。三是创新设计共轨飞行模式,独具中国特色。设计新型平台装载大型光学设施,与空间站共轨飞行,必要时停靠空间站进行维护和补给,开辟了分布式空间站体系构架的创新模式,应用前景广阔。四是利用高新技术,提高综合效能。综合利用电子技术、信息技术和能源技术的最新成果,提高航天员操作、使用、维护维修和科学实验效率,将空间站运营管理效益和使用效能显著提升到一个新水平。
目前,我们已完成空间站方案设计和关键技术攻关,空间站各舱段及其配套运载火箭、有关试验载荷等各类飞行产品正在进行研制生产和地面试验,载人飞船、货运飞船及其配套运载火箭等正在按计划生产。
