According to the news, what has happened last autumn?
Last October, a NASA rocket travelling 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 higher 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.
