避免人类灭绝，NASA发射航天器撞向小行星【暴虐朗读】

【头条播报】
NASA launched a new kind of spacecraft recently. Its mission is to smash into an asteroid and see whether it would be possible to knock a speeding space rock off course if one were to threaten Earth. The technology could prove useful for altering the course of an asteroid on a collision course with Earth years or decades before a potentially catastrophic impact.
