《世界末日》真实版：科学家尝试炸掉小行星

　　Scientists plan to fire a spacecraft into an asteroid in an effort to prepare for one being on a direct collision course with Earth。

　　In the Hollywood movie Armageddon, Bruce Willis attempts to blow up a huge asteroid hurtling towards Earth。

　　In real life, the trial, dubbed Don Quixote, will see two spacecraft launched。

　　One will attempt to push the asteroid off its course while the second will collect valuable data from the impact。

　　And the European Space Agency planed the trial。

　　A potential target for the mission is a 1,600ft-wide asteroid called 99942 Apophis, which has a remote chance – roughly one in 250,000 – of hitting earth in 2036.
