What’s the distance did the spacecraft make the free fall? [br]
If one rocket scientist’s observations are right, the fuzzy dots on a grainy black-and-white photo from Mars show the wreckage of a NASA probe which vanished in 1999 Just before it was supposed to land on the red planet. After it disappeared, the Mars Polar Lander Mission was declared a 165, 000, 000 dollar failure.(25)A NASA team concluded an engine probably shut off early, causing the spacecraft to free fall about 130 feet, causing almost certain destruction on the Martian surface.
" Landing on Mars is very hard. And it’s the part of your landing where things get really hard and, you know, it doesn’t take much. "
(26)Some experts think the spots in this photo show the Polar Lander’s wreckage is pretty much intact 6 years after the accident. NASA’s calling the scientist’s new analysis intriguing.
选项
A、the Polar Lander’s wreckage just left some spots
B、the Polar Lander’s wreckage cannot be found in the Mars now
C、the Polar Lander has never landed on the Mars
D、the Polar Lander’s wreckage is intact for 6 years after the accident
答案
D
解析
本题考查对新闻细节的捕捉。根据句(26)可知,一些专家认为照片上的模糊的黑点显示失事的太空船的残骸在事件发生后的6年内没有被人碰过。因此D为正确答案。
