美国宇航局利用一颗卫星撞向月球南部极点的一座火山口，在随之激向大气的岩石和灰尘中发现了大约24加仑的冰冻水。

The equivalent of 24 gallons of frozen water, mixed in with the rock and dust that was thrown into the air when a rocket was deliberately crashed into a crater near the Moon's south pole last month.

日本科学家和美国科学家一样，掌握相似的返回样本，曾在2010年利用探测仪隼鸟号从一颗彗星羽中检测到灰尘。

The Japanese, like the Americans, have experience with sample-return of this sort, having flown a probe called Hayabusa that retrieved dust from the plume of a comet in 2010.
