NASA successfully crashes DART spacecraft into Dimorphos asteroid

mission accomplished

NASA successfully crashed a spacecraft into an asteroid on Monday, marking a victory for the agency’s plan for when a devastating asteroid should ever threaten humanity.

The 1,260-pound Twin Asteroid Redirection Test spacecraft, or DART, collided with the estimated 11 billion-pound, 520-foot-long asteroid Dimorphos at 14,000 miles per hour about 7 million miles from the land

The spacecraft had launched its camera and a shoebox-sized companion, LICIACube, more than a week ago to photograph the mission, which confirmed the impact.

“This was a really tough technology demonstration to hit a small asteroid that we’ve never seen before and do it in such a spectacular way,” said Nancy Chabot, a planetary scientist and mission team leader at Johns University. Hopkins, after impact.

The completed mission caps a 10-month journey for DART, which cost $325 million. The asteroid orbits a larger one called Didymos, and the two were chosen because they pose no threat to Earth.
