NASA will smash DART probe into 'Dimorphos', a moon as big as Egypt's Great Pyramid - CNET

NASA's DART spacecraft will blast off to asteroid Didymos to crash into its moon. .

NASA's Double Asteroid Redirection Test (DART) mission will reach an asteroid named Didymos in 2022 as a demonstration of an asteroid deflection system designed to redirect a space rock away from an Earth impact.

Didymos' moon is the target of the exercise and it was saddled with the temporary name "Didymos B" until the International Astronomical Union approved the new name "Dimorphos" this week. .

DART is designed for a kinetic impact, which means it will crash into Dimorphos in an effort to nudge it.

Two years later, ESA will launch its own Hera spacecraft to visit Didymos and examine the results of the DART mission.
