What’s the distance 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.(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、130 meters.
B、130 kilometers.
C、130 feet.
D、113 feet.
