The fifth attempt proved to be the charm on Friday as the Falcon 9 touched down on a football-sized platform in the Atlantic Ocean.
周五，SpaceX在大西洋進行第五次嘗試，此次嘗試完美無瑕，“獵鷹9”號火箭著陸在球場大小平臺。
The SpaceX mission first delivered a Dragon cargo capsule into orbit for the International Space Station.

After separating from the capsule, the first-stage of the rocket began a controlled descent back to Earth's surface.

The method is expected to save dramatically on the cost of sending supplies to orbit, not only for SpaceX but also NASA, as the reusable rocket stage currently costs $60 million.
不僅是SpaceX，而且對于美國航空航天局而言，此舉有望大大降低運輸費用，目前可回收火箭報價為6000萬美金。
