Watch a Nicely Stabilized Video of DART Flying Past Didymos and Slamming Into Dimorphos

Here’s one of the best videos we’ve seen of the last minutes of the Double Asteroid Redirection Test (DART) mission as it headed towards and slammed into the asteroid Dimorphos. This stabilized version of the last five-and-a-half minutes of images leading up to DART’s intentional collision with the asteroid was produced from NASA’s DART images. It was produced by the YouTube channel Spei’s Space News from Germany.

This is the Last Thing DART saw as it Smashed Into its Asteroid Target

The first-ever planetary defense technology demonstration mission successfully conducted its mission, slamming into the surface of a distant asteroid and going out in a blaze of glory. NASA’s Double Asteroid Redirection Test (DART) spacecraft acted as a kinetic impactor, colliding with the small and harmless asteroid Dimorphos on September 26 at 7:14PM ET, with the hope of deflecting it.

The World’s Ground Stations are Getting Ready to Watch a Spacecraft Crash Into an Asteroid Next Week!

On September 26th, NASA’s Double-Asteroid Redirect Test (DART) will rendezvous with the Near-Earth Asteroid (NEA) Didymos. By 01:14 UTC (07:14 PM EDT; 04:14 PM PDT), this spacecraft will collide with the small moonlet orbiting the asteroid (Dimorphos) to test the “kinetic impactor” method of planetary defense. This method involves a spacecraft striking an asteroid to alter its orbit and divert it from a trajectory that would cause it to collide with Earth. The event will be broadcast live worldwide and feature data streams from the DART during its final 12 hours before it strikes its target.

DART Sees Asteroid Didymos for the First Time. In two Weeks, it’ll Crash Into its Moon

NASA’s Double Asteroid Redirection Test (DART) mission is on its way to rendezvous with the double-asteroid Didymos. When it arrives on September 26^th, DART will collide with Dimorphos – the 160-meter (525-foot) moonlet that orbits the main body – to evaluate the kinetic impact technique for the very first time. This proposed method of planetary defense consists of a spacecraft colliding with an asteroid to alter its orbit and prevent it from colliding with Earth. In July, DART took its first image of the double-asteroid, which NASA released earlier this week!
