央视网消息:一箭凌云九霄重,万里星河追梦,神舟探苍穹。4月24日17时17分,搭载神舟二十号载人飞船的长征二号F遥二十运载火箭 在酒泉卫星发射中心点火发射,约10分钟后,神舟二十号载人飞船与火箭成功分离,进入预定轨道。目前,航天员乘组状态良好,发射取得圆 满成功。 飞船入轨后,将按照预定程序与空间站组合体进行自主快速交会对接,神舟二十号航天员乘组将与神舟十九号航天员乘组进行在轨轮换。 当0号指挥员下达"点火"指令,长二F火箭伴随着一团烈焰垂直腾空而起。火箭起飞重量约500吨,90%都是液体燃料的重量。 大概12秒后,火箭不再垂直向上飞行,而是拐一个弯,沿着地球的倾斜度来飞行,这样可以节省燃料,这一动作叫做程序转弯。 飞行至120秒左右,逃逸塔完成使命并与火箭分离。这时,火箭的飞行高度大概在40公里左右。尽管逃逸塔分离,但这并不意味着航天员 的安全保障就此结束,高空逃逸发动机等将继续为航天员保驾护航。 接下来,火箭飞行到152秒左右,四个助推器将耗尽燃料,它们会同时与火箭主体脱离,让火箭继续轻装前行。 几秒钟后,一级火箭也将耗尽燃料,火箭一二级分离,由二级火箭继续带着飞船加速前行。 此次任务是我国载人航天工程进 ...
