Bam! NASA spacecraft crashes into asteroid in defense test
The galactic slam occurred at a harmless asteroid 7 million miles (9.6 million kilometers) away, with the spacecraft named Dart plowing into the space rock at 14,000 mph (22,500 kph). Scientists expected the impact to carve out a crater, hurl streams of rocks and dirt into space and, most importantly, alter the asteroid's orbit.
NASA's DART spacecraft hits target asteroid in test of planetary defense system
Hurtling through the solar system at hypersonic speed on Monday, NASA's DART spacecraft slammed itself into a distant asteroid in a test of the world's first planetary defense system, designed to prevent a potential doomsday meteorite collision with Earth. The finale to the suicide spaceflight, humanity's first attempt to alter the motion of an asteroid or any celestial body, played
