2015考研英语阅读太空之旅送我入太空

　　神剑的庞大空间站需要更多的工作使其成为旅月航天器。第一步将需要安装引擎。公司计划使用例子推动器，这是一种高科技的推动系统其推动剂是一种电场。这种发动机效率非常高，并且可以从空间站太阳能电极板得到能量。但是他们进展缓慢，意思是神剑的使命可能至少推迟6个月，相比于空间探索公司仅仅需要6天就能加注的化学推动剂飞船。事实上，神剑计划的低能量轨道将能把它的工作人员送到离地球比以前所有人都远的地方。

　　A journey that long would be risky. One danger is from unpredictable and potentiallydeadly solar flares, giant releases of stellar energy that would bombard the craft withradiation and fry its occupants. To protect its passengers, the company plans to build aninternal storm shelter that uses the spacecraft s water supplies to absorb radiation.

　　长距离的旅行将很危险。危险之一来自不可预定和可能的致命的太阳耀斑，恒星能量的巨大释放将用射线炸毁飞船并且烧焦乘客。为了保护乘客，该公司计划建立内部风暴掩体用飞船的供水系统来吸收射线。

　　Neither firm will start refitting its spacecraft, a process expected to take around threeyears, until it has sold all the seats on its maiden flights . The companies are marketing their lunar missions to the same high-techentrepreneurs and ultra-rich thrill-seekers who have snapped up tourist visits to the ISS andsuborbital joyrides-long planned, but yet to fly-with firms such as Virgin Galactic.
