中国航天科技集团 刁伟鹤：我们发现神舟二十号舷窗出现微细裂纹后，组织了全面、系统评估和维修方案设计。神舟二十二号会上行部分维修工具，进行 在轨相应处置。 神舟二十二号飞船是新一批次神舟飞船的首发船，这艘飞船进行了两项主要改进。一是对仪表系统进行了大幅升级，使人机界面更加美观友好，二是通过仪 表板小型化，为返回舱腾出了更多空间。 （央视财经《经济信息联播》）神舟二十二号飞船本次执行的是"应急发射"任务，同时也是首次实现"无人上行物资+载人下行"的灵活模式。此次发射的神 舟二十二号飞船是新批次飞船的首发船，它有哪些改进？ 与以往任务不同，神舟二十二号飞船本次执行的是"应急发射"任务。该任务源于在轨神舟二十号飞船因遭遇微小空间碎片撞击，舷窗出现微细裂纹。 此次应急发射，将原本需要数十天的发射准备流程压缩至短短的16天。这对飞船的总装、测试、加注以及与各大系统的联调联试工作提出了极限挑战。除此 之外，此次任务神舟二十二号飞船还肩负着一项特殊使命。 中国航天科技集团 郑伟：整个仪表系统做了大的改进，让人机界面看起来更漂亮一些，第二是它的尺寸大幅度缩小了，给返回舱下行载荷提供了比较大的 安装空间。 转载请注明央视财经 编 ...
