NASA’s DART Mission

Post by jeff.stevens »

I’ve just watched the end of NASA’s DART mission, as it impacted Dimorphos. What an incredible time to be alive to see the culmination of such a task, and to see such close up images of the surface of an asteroid.

It will be interesting to follow the assessment of the mission, and the details of how the asteroid’s trajectory has been changed.

Best wishes, Jeff.

An interesting ground-based video of the impact can be found on today’s SpaceWeather.com website.

Best wishes, Jeff.

Amazingly, DART was only 17metres from its planned impact point after having travelled so far.

There’s an interesting “How To…” guide available now, explaining how to make a comet-like object in the night sky.

Best wishes, Jeff.

On October 11th, NASA will announce whether are not DART has caused an orbital change to the little asteroid around its primary.

Thanks Brian, I'll keep an eye open for news of this. I wonder how much research went in to selecting this particular binary object?

Best wishes, Jeff.

It’s official, NASA says that DART has affected the orbit of Dimorphos. More information is still coming in.

I wonder if they went with top spin or side spin on the cue ball :wink: ?

It’s very interesting.

Best wishes, Jeff.

According to today’s www.spaceweather.com Dimorphos is splitting in two

Yes, it doesn't give too much detail on why the tail has split in two - I guess that will be discussed more over the coming days. The Nature article is quite interesting too. It points out that the full "post-mortem" for the mission will take at least a decade. That's a big task!

Best wishes, Jeff.

Maybe Dimorphos is splitting in two because it’s only a loose rubble pile asteroid.

The problem with nudging asteroids is that an asteroid that was just going to miss the Earth is nudged into hitting the Earth.

I think we should just take our chances unless some perfect way is guaranteed.
