How did the "sound" get to our receiver?  I get that a cluster could have enough gas to be a vehicle for soundwaves, but I'm assuming there is a very large vacuum between the gas filled cluster and the receiver used to collect the data.

 

Please, no one take this as "scientists are lying to us!", I'm genuinely curious.

The sound doesn't reach us. Instead astronomers measure the pressure waves (I assume from x-rays since the Chandra X-ray Observatory is producing the data) and then convert that to the equivalent sound.

 

Edit: it's from a variety of sources: x-ray, visible light, and radio waves.

It will be interesting to see if Artemis 1 launches Tuesday via SLS with a possible hurricane on the way. I know they have a plan to do an express rollback to the VAB if need be.

I'm not a scientist or anything, but watching that video makes me think it would not be ideal if that were to happen.

It's the kind of thing that would ruin your whole day.

So, did NASA just complete the event that will cause the first interplanetary war? Imagine the altered path asteroid now being on course to smack an inhabited planet.

In all serious though, kind of cool.

This is a cool, unusual perspective of a launch.
