DART is a planetary defense-driven test of technologies for preventing an impact of Earth by a hazardous asteroid. DART will be the first demonstration of the kinetic impactor technique to change the motion of an asteroid in space.

DART’s target is actually a twin asteroid/planetoïde: Didymos (780 m in diameter) and Dimorphos (160 m in diameter) , and DART will impact on the smaller one. Both are NOT a threat to Earth.

The launch of the 70-meter tall Falcon 9 rocket is poised for takeoff from Space Launch Complex 4-East at Vandenberg Space Force Base, California, today at 10:21:02 p.m. PST on Nov. 23 (1:21:02 a.m. EST; 0621:02 GMT on Nov. 24).

The American space agency's DART Aspace probe has successfully smashed into an asteroid, destroying itself in the process. DART is the first-ever mission dedicated to investigating and demonstrating one method of asteroid deflection by changing an asteroid’s motion in space through kinetic impact.

DART's camera returned an image per second, right up to the moment of impact with the target - a 160m-wide object called Dimorphos.

The same technique could be used to deflect space rocks that threaten Earth.

The DART (Double Asteroid Redirection Test) seems to be successful, NASA confirms it had shortened Dimorphos' orbital period by about 32 minutes, surpassing the success threshold of 73 seconds.

NASA Confirms DART Mission Impact Changed Asteroid’s Motion in Space

Analysis of data obtained over the past two weeks by NASA’s Double Asteroid Redirection Test (DART) investigation team shows the spacecraft's kinetic impact with its target asteroid, Dimorphos, successfully altered the asteroid’s orbit. This marks humanity’s first time purposely changing the...

Hera's primary objective is to study the Didymos binary asteroid system that was impacted by DART in September 2022 and contribute to validation of the kinetic impact method to deviate a near-Earth asteroid in a colliding trajectory with Earth. It will measure the size and the morphology of the crater created and momentum transferred by an artificial projectile impacting an asteroid, which will allow measuring the efficiency of the deflection produced by the impact. It will also analyze the expanding debris cloud caused by the impact.

The Hera spacecraft is cubic in shape, 1,6 × 1,6 × 1,7 meters and has a mass of approximately 1128 kg. Besides the payload of cameras, an altimiter and spectrometer, it also carries two small cubesats, named Juventas and Milani.

Hera will not be launched by ESA self, but by a Falcon 9 Block 5 rocket.
The launch is planned for today.
