DART Made a Surprisingly Big Impact on Dimorphos

NASA’s DART (Double Asteroid Redirection Test) mission was hailed a success when it collided with its target asteroid Dimorphos last year. The purpose of the endeavour was to see if it could redirect an asteroid and, since the impact, astronomers have been measuring and calculating the impact on the target. It is incredible that the 580kg spacecraft travelling at 6 km/s was able to impart enormous kinetic energy to the 5 billion kg asteroid.

What Happened to All Those Boulders Blasted into Space by DART?

It was a $325 million dollar project that was intentionally smashed to smithereens in the interest of one day, saving humanity. The DART mission (Double Asteroid Redirection Test) launched in November 2021 on route to asteroid Dimorphos. Its mission was simple, to smash into Dimorphos to see if it may be possible to redirect it from its path. On impact, it created a trail of debris from micron to meter sized objects. A new paper analyses the debris field to predict where they might end up.

DART Showed We Can Move an Asteroid. Can We Do It More Efficiently?

Like many of you, I loved Deep Impact and Armageddon. Great films, loads of action and of course, an asteroid on collision course with Earth. What more is there to love!  Both movies touched upon the options for humanity to try and avoid such a collision but the reality is a little less Hollywood. One of the most common options is to try some sort of single impact style event as was demonstrated by the DART (Double Asteroid Redirection Test) mission but a new paper offer an intriguing and perhaps more efficient alternative.

Occultation Chasers Nab the Shadow of Didymos, Post DART Impact

Occultation
Setup

A worldwide team of dedicated observers ‘stood in the shadow’ of asteroid Didymos recently, as it passed in front of a distant star.

Amateur astronomers continue to provide key scientific observations, even in the modern era. This was highlighted recently, when a team of dedicated observers caught a series of occultation of a distant stars involving asteroid 65803 Didymos.
