练案[16] UNIT 4  JOURNEY ACROSS A VAST LAND Section Ⅳ  Writing Ⅰ. 阅读理解     On July 11th Virgin Galactic finally realized the promise that it would take passengers on life ̄changing trips in its spaceships. For 4 minutesꎬ its six temporarily weightless passengersꎬincluding the firm􀆳s co ̄founderꎬ Sir Richard Bransonꎬ saw the planet􀆳s curvature ( 曲 度 ) against the blackness of outer space. He may have gloated (窃喜) over beating Jeff Bezos ( much richer )ꎬ Amazon􀆳s retired bossꎬ who would go slightly higherꎬ for slightly less timeꎬ in a vehicle built by his own companyꎬ Blue Originꎬ on July 20th.

UBS (瑞银集团) expects the entire space economy to produce $ 800 billion by the end of this decade. Space tourismꎬ it thinksꎬ will make “ a big contribution” to that total. But that is highly unlikely. For exampleꎬ space tourism is not even Blue Origin􀆳s main goal. The company is focusing on developing a large new rocket for launching satellitesꎬ on selling advanced rocket engines to other companies and on winning NASA contracts such as that for a system to land humans on the Moon.

The business could be profitable once regular flights begin to offset ( 抵 消 ) the rockets􀆳 development costs. But how fast and by how much is uncertain. Without tourist ̄friendly destinations to visitꎬspace tourismꎬwith its far higher ticket pricesꎬ will not be a huger earner. Another challenge—and the biggest uncertainty— relates to safety. History has shown that a disaster can set progress back by years. Even with no accidentsꎬ problems may arise. Strict top down regulation
