人类科技里程碑！SpaceX 成功发射 Falcon 9 火箭并完成一级火箭回收

美国东部时间 12 月 21 日晚，SpaceX 在佛罗里达州卡纳维拉尔角成功发射 Falcon 9 火箭，并在火箭升空后 10 分钟完成了第一级火箭的回收任务，这是人类历史上第一次可实现一级火箭垂直回收的轨道飞行器。

真人 “钢铁侠” Elon Musk 会改写多少科技历史我们不得而知，但是在最近 SpaceX 成功发射 Falcon 9 火箭后，又在人类卫星科技领域留下了重要里程碑式意义。

美国东部时间 12 月 21 日晚，SpaceX 在佛罗里达州卡纳维拉尔角成功发射 Falcon 9 火箭，并在火箭升空后 10 分钟完成了第一级火箭的回收任务，这是人类历史上第一次可实现一级火箭垂直回收的轨道飞行器。这次巨大的成功让 SpaceX 在人类科技领域写下了浓墨重彩的一笔，虽然早前也有过失败，但最终还是在今年完成了这一宏伟计划。

垂直回收一级火箭有多困难？给大家一个生动的比喻：这就好比把一根普通的铅笔，发射过帝国大厦的高度，然后旋转返回，最终在风暴中安稳垂直着陆。成功回收一级火箭的更重要意义是 SpaceX 极大降低了火箭发射成本，以往进入太空轨道后火箭都会毁灭或者丢失，但这次成功回收则标志着在未来火箭也可以重复利用，真正开启廉价航空时代。下面各位不妨点击视频，浏览这次 SpaceX Falcon 9 火箭的回收过程。
