NASA is ready to test a planetary defense system that could one day prevent a “dangerous asteroid” from hitting Earth.

NS The space agency said on Tuesday The dual asteroid deflection test (DART) mission is scheduled to launch on a SpaceX Falcon 9 rocket on November 24 from Vandenberg Air Force Base in California.

The mission will test an asteroid defense plan called kinetic impact technology, which involves launching a spacecraft into an asteroid at about 15,000 miles per hour to essentially change course.

“DART will be the first demonstration of kinetic impact technology to alter the motion of an asteroid in space,” NASA said. Said. Declaration.

DART will target a binary asteroid called Didymos. The asteroid system consists of an asteroid 780 meters high and a “little moon” 160 meters wide.

Using cameras and autonomous navigation, the spacecraft will deliberately crash into the Moon at 6.6 kilometers per second, NASA reported.

“The collision will change the velocity of the small moon in orbit around the main body by one percent, but will change the orbital period of the new moon by a few percent — enough that it can be observed and measured using telescopes on Earth,” he said. said the agency. .

After nearly a year of space travel, the spacecraft is scheduled to reach the new moon of Didymos in September 2022.
