1.The space craft will not land on the moon, though it will send a small "impactor" probe to the surface.
飞船将向月表发射一枚“撞击”探测器，但是不会在月球着陆。
2."In a way you do make a crater, but you fill it all in with the impactor material, " says Asphaug.
“从某种意思上说，碰撞过程中产生过环形山，但是参与碰撞的物质又把它填满了。”Asphaug说到。
3.The impactor: A large spacecraft slams into the asteroid hard enough to jolt it off its Earth-bound track.
冲撞器：一架巨型太空飞行器猛力撞上小行星以让它偏离直冲地球的轨道。
4.The test variables include the effects of changing the size of impactor and distance between impactor and receiver.
实验变数包括改变敲击元尺寸及接收器距离对检测的影响。
5.The presence of hydrocarbons, and the absence of carbon monoxide, provide strong evidence for a water-depleted impactor in 2009.
出现了碳氢化合物，没有出现一氧化碳，强烈显示2009年的撞击物是缺水的。
6.Deep Impact first visited Comet Tempel 1 in 2005, crashing an impactor into the comet to help scan its composition from afar.
“深度冲撞”号于2005年第一次造访了彗星Tempel1，为了分析该彗星的构成，它抛出了一个冲撞器。
7.Impactor handwheel (3-10 times more effective than standard handwheel).
冲击性手轮（比普通手轮效率高出3至10倍）
8.Apophis has in the past been claimed as a possible future impactor when it returns to our neighbourhood in 2029 and again in 2036.
过去曾断言，当阿波菲斯于2029年和2036年两次返回到我们周边太空时，它将可能撞上地球。
9.Size distributions of mutagenic compounds and mutagenicity in atmospheric particulate matter collected with a low-pressure cascade impactor
