That&`&s because rocketry is the only form of transportation where you throw away your vehicle once you’ve reached your destination. But that might change as soon as January of next year, when Space Exploration Technologies, also known as SpaceX, plans to launch a rocket into space, then bring the rocket’s first stage back for a precision landing. 达到地球外太空的运行轨道地带大概的单价是每公里1万到20万美元（这打的可是火箭，火箭阿。。。）。这还不是因为你一旦到达目的地就要抛弃的唯一交通工具是火箭么。但是到明年一月份这种铺张浪费的情况会有所改变的，那时太空探索技术，又被称为SpaceX，计划发射一枚火箭到太空，然后会把火箭的第一节推进器再准确的带回到发射基地。 After launching a payload on a resupply mission to the International Space Station, Space X’s Falcon 9 first stage will deploy hypersonic stabilizing fins and fire its engines four times, steering itself to an upright touchdown on a robotic barge floating in the Atlantic Ocean. Think of a 14-story building moving faster than a kilometer per second. And now imagine slowing it down, balancing it on a jet of rocket exhaust and landing it with an accuracy of 10 meters on a target smaller than a football field. 在发射一个有补给用品到国际空间站任务的火箭后，Space X’s 猎鹰9号的第一节回展开朝高音速稳定散热片并开动4次引擎，引导自己垂直降落到大西洋上飘着的一格机器驳船上。脑补一下一个14层楼高的建筑运动速度超过每秒一公里的惊悚画面吧。现在再想象一下，将它减速，在一个喷气式火箭上平衡它的各种动量，再把它精准的降落在比一个足球场还稍小的地方，误差不超过10米。 It won’t be easy—company representatives only give the precision landing 50–50 odds. But if successful, SpaceX’s audacious test could soon lead to cheaper, fully reusable rockets that make the final frontier not quite so financially challenging. 这肯定不容易——该公司的代表只给出50-50对半几率的准确着陆可能性估计。但，如果成功了呢，SpaceX’s 这个大胆的测试必将迅速引发更廉洁，完全可重复利用的火箭设备，这些都将会促使人类对最后的未开发神秘地带的探索不再那么的烧美元。
