According to the news, what has happened last autumn?
Last October, a NASA rocket, traveling at a speed of 9,000 kilometers per hour, smashed into a dark crater on the moon’s south pole.
Upon impact, the Centaur rocket kicked up a cloud of debris and elements from the moon’s surface, creating a so-called "ejecta-plume" that was monitored by NASA’s Lunar Reconnaissance Orbiter, or LRO.
Scientists analyzed the findings, and preliminary results from this mission, as well as others, suggested that there was some form of water on the moon. NASA lunar scientist Michael Wargo said those days that a wave of findings during the past year makes it certain.
"We’ve confirmed that there was indeed water ice in the ejecta-plume, and at an abundance that was about 50 percent greater than our initial estimates."
That means that the impact site has more water than some deserts on Earth.
选项
A、A rocket has been successfully launched.
B、There was a rocket hitting the moon.
C、A deep crater appeared on the moon’s South Pole.
D、There was an amazing finding made by LRO.
答案
B
解析
细节题。新闻中指出,美国宇航局的一枚火箭以每小时9000公里的速度,撞上月球南极的一个黑暗陨石坑而粉碎。这与B项的“火箭撞月”意思相同,故正确答案是B。
