Wait 'till scrubtember goes out without a bang when DART misses the asteroid lol

That's what we're watching.

What's the other one? (The stream has "TGO" on the left and "ROI box within DRACO FOV" on the right.)

NASA's stream is pics only, NASAspaceflight has commentary.

The image at the left is the digitally-centered view of the target. The DRACO camera on DART has an overall field of view (FOV) which is shown in total at right.

NASA tv is providing commentary as well

It's gonna be fuzzy dot... fuzzy dot.... Fuzzy Dot.... FUZZY DOT.... ASTEROID CLOSEUP... lost signal.

My assumption is that the right hand image is the entire field of view of the camera, but either to save on bandwidth, or to zoom in, only part of the image is being displayed (centered on the asteroids, like some kind of image stabilization). That is the left hand box. The right hand box shows that image's location in the full field of view.

Guy on the Dart Livestream:

You don't want to blow up an asteroid. The pieces will still hit earth. You don't want to miss a thing.

I refuse to believe this wasn't an overt reference to that awful scene in Armageddon with the animal crackers.

Yes you want to redirect, if that is not practical you want to blow it up into small enough fragments the atmosphere, yes that require an nuke, you still want an mostly redirect 
And atmosphere is serious armor. Now it has serious political issues say you had an 200 MT blast in the Pacific but you get multiple 50 KT impacts in California.

Obligatory:

Sadly I'm in class RN so I can only follow along with non-audio sources.

DART is now approximately one Earth radius away from impact and closing at 20 times the speed of sound.

I just thought I saw an asteroid simulation that was in ksp 

[Nuke]

hey cool i woke up in time to watch it. this never happens. stupid depression. 

[StrandedonEarth]

Was able to surf the thread just in time to discover I haven’t missed it. Now running the NASA feed on YouTube on the Roku TV with now exactly 13 minutes to go… mark!

[Gargamel]

Read somewhere that even JWST is observing this one.

Ahhhh, OK. So when the one on the right jumps around, is it:

1. panning the camera?
2. tapping the RCS to fine-tune the approach?
3. none of the above?

Probably a combination of RCS and small perturbations.

We have a meaningful view of the Dimorphos disc:

We are in the Fuzzy dot phase...   Fuzzy Dot is next.

5 minutes!

"Contingencies done haha"

Lets make the Deep Impact team proud

[cubinator]

My streams are not synced, I will watch it twice lol

[Zozaf Kerman]

No more maneuvers! I’m only here for the explosion though.

[sevenperforce]

Impact in 5 minutes. 60 seconds until the start of the final correction burn. Clear detail visible on Didymos and some on Dimorphos. DART is about as far from Dimorphos as New York City is from Cape Canaveral.

2 minutes

It's getting lumpy!
