马斯克的SpaceX成功用二级猎鹰9号火箭「龙」飞船(Dragon capsule)送入太空,执行为国际空间站运输物资的任务。火箭点火发射时如图,若高温火焰向下喷射到发射台上,发射台就会被烧毁。为了保护发射台,在它的底部建造了一个大水池,从而巧妙地解决了这个技术问题。 (1)9 号火箭发射时,底部喷出的庞大的白色气团是由什么组...
Dragon Capsule被认为可以处理所有想象中的情况,包括火箭飞行中的故障。 如果发生这种情况,该船将使用强大的内置推进系统将自己推到安全距离,SpaceX在地面和空中都预演了这种可能性。 飞行约19个小时后,该任务应使Dragon到达ISS,太空舱将与空间站的船首对齐,并以每秒几厘米的相对速度接近。 工程师说,“载人龙”号上...
