How tall did the spacecraft make the free fall?
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. 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."
Some exports 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、130 meters.
B、130 kilometers.
C、130 feet.
D、113 feet.
答案
C
解析
对新闻细节(数字)的捕捉。新闻中讲到:“A NASA team concluded an engine probably shut off early, causing the spacecraft to free fall about 130 feet...”可知宇航局的人认为可能是太空船的一个引擎突然熄火,使得太空船从130英尺高的空中落下,在火星表面毁坏。选项C为正确答案。
