模仿文本： Exploraton is always bold and always fraught with risk, from Antarctica to the boundaries of space, from President Kennedy's famous speech at Rice University to the conquest of the Moon less than seven years later, from today's international space station to that prediction that we could have the ability to go to Mars in a little over a decade. 

 

译文： 探险总是勇敢无畏，同时也充满危险——从南极洲到太空边界，从肯尼迪总统在莱斯大学的著名演讲到此后不足七年的征服月球之举，从今天的国际空间站到那段预言，说我们在十年多一点的时间内就能去到火星——莫不如是。
