A NASA spacecraft rammed an asteroid at blistering speed Monday in an unprecedented dress rehearsal for the day a killer rock menaces Earth.
The $325 million mission
was the first attempt to shift the position of an asteroid or any other natural object in space.
The galactic grand slam occurred at a harmless asteroid 7 million miles away
with the spacecraft named Dart plowing into the small space rock at 14,000 mph.
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.
