Where did the damage happen?
In this image released by NASA TV, the space shuttle Discovery’s robotic arm gives NASA workers a close-up view of the damage to the thermal blanket. The U.S. space agency NASA has cleared the shuttle Discovery for re-entry Monday with no need for another repair spacewalk. The crew has finished most of its work at the International Space Station and took time Thursday to remember fallen astronauts and cosmonauts.
After a mission fraught with worries about problems with Discovery’s fragile heat shield, shuttle officials say the orbiter appears safe to come back to Earth.
The last issue engineers hurried to analyze was a loose piece of thermal blanket below the cockpit window, believed torn during Discovery’s launch by debris falling off its exterior fuel tank. NASA feared that if the fabric ripped away during the high-speed descent through the atmosphere, an impact could damage Discovery’s tail or braking rudder.
选项
A、Robotic arm.
B、Thermal tank.
C、Robotic blanket.
D、Thermal blanket.
答案
D
解析
根据新闻第一句:The space shuttle Discovery’s robotic arm gives NASA workers a close-up view of thedamage to the thermal blanket.可以选D。不过这里注意B选项,可能在听的时候会听成B,其实文章后面也有提及thermal blanket,看题的时候认真一点就行。 .
