Boom!! DART succeeds!

The DART probe just impacted the Asteroid Dimorphos. The image sequence was amazing, though I can't find any online right now.



"In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion." (1987) -- Carl Sagan

Here's the video. Skip ahead to approximately 1 hour and 14 minutes into the video. [www.youtube.com]

But did it achieve the desired outcome of changing the objects course?



It is what it is.

i think i heard it would take awhile to analyze the data to figure that part out.

I don't think we know just yet whether or not the course will be altered.

It's a heck of a shot in all respects.

But I'm concerned about alien retaliation when somebody finds out we destroyed their underground summer bungalow.

What's really amazing is that we managed to send something the size of a golf cart to hit a target the size of a couple of football fields in diameter and about 7 million miles from Earth at a speed of about 15,000 mph. The numbers are simply mind-boggling.

So the current high score is 1?

Yep. It's like a championship soccer match...1-0.

Absolutely. At an impact velocity of 15k MPH on an asteroid/moon less than 200 yards in diameter, well, you can do the math.

...it will take as long as a couple of months to determine how much the asteroid’s path was changed.

And:

Scientists insisted Dart would not shatter Dimorphos. The spacecraft packed a scant 1,260 pounds (570 kilograms), compared with the asteroid’s 11 billion pounds (5 billion kilograms). But that should be plenty to shrink its 11-hour, 55-minute orbit around Didymos.

The impact should pare 10 minutes off that. The anticipated orbital shift of 1% might not sound like much, scientists noted. But they stressed it would amount to a significant change over years.

“Now is when the science starts,” said NASA’s Lori Glaze, planetary science division director. “Now we’re going to see for real how effective we were.”

Would it not matter the direction of the impact? To my VERY rudimentary understanding of physics, if you hit it from behind, it would speed up and if you hit it head on it might slow it up and if you hit it from the side it might wobble a bit.

I stand in awe of the mathematics of this accomplishment. In15 years (or whatever) the object will be in THIS location and we can build a satellite send a it a few million miles out to intercept it. From a spinning earth that is pointed the wrong way most of the day.

I alluded to this in my first post, but I had no idea of the scale.

That elevates my take from amazing to freakin' awesome!

Full disclosure: My mind is easily boggled by maths.
