近來，太空產業競爭加劇：6月底，初創商SpaceX為美國國防部、台灣等地客戶發射（launch）衛星，完成「有史以來最艱難任務」；電商龍頭亞馬遜創辦人貝佐斯的藍源（Blue Origin）也預計在今年啟動短程載客的太空旅行計畫。
【太空爭霸淺談】
to launch 發射
A：SpaceX created the first-ever reusable rocket, which marks a major step to cheaper space travel.
（SpaceX研發出史上首座能大幅降低太空旅費的可回收火箭。）
B：Blue Origin has launched its reusable rocket 11th times and is more likely to achieve space tourism.
（藍源的回收火箭已成功11次，更可能實踐太空旅遊呢。）
to take on 接受（挑戰）
A：The Falcon Heavy has launched 24 satellites, including the Formosat-7 that's co-developed by NSPO and the U.S.
（獵鷹重型已發射24枚衛星，包含台美共同研發的福衛7號。）
B：Blue Origin is taking on SpaceX not only in reusable rockets but also in heavy-lift rockets.
（藍源公司除了可回收火箭，也正面挑戰SpaceX的重型火箭。）
to carry 乘載、運送
A：I heard that the massive New Glenn rocket they built is as tall as a 29-story skyscraper.
（聽說他們打造的巨型新格蘭火箭高度相當於29層摩天大樓。）
B：Compared to the Falcon Heavy which only carries satellites, it aims to fly humans into space as well.
（與只載衛星的獵鷹重型相比，它的目標還包含載人到外太空。）
