Radio Science Part 1 - ua-cam.com/video/MauuL531fRY/v-deo.html It's a quick and general overview. If you like small UA-camr science channels check out the subreddit I've created just for that. www.reddit.com/r/SmallUA-camrScience/ Show these creators some love.
Yeah, what's also amazing is how they can separate all the different forces affecting the spacecraft. BTW I used your rock making technique to make the rocks at 9:18
again, a superlative mastery of the material. I'm not a scientist but I am closely familiar with all the underlying physics. I never see any glaring error or misunderstanding or misconception anywhere in these. Exceptional presentation.
Thanks, I try to do justice to the scientific papers but avoid falling into rabbit holes where the explanation needs an explanation. Kinda almost happen. Whenever I talked about planetary model I was tempted in explain that in more detail. But the video would start to get too long. I try to make a 10 min video but that's not been the case lately.
@@ReflectiveLayerFilm I'd for one watch no matter the length, I think the audience on here is willing to watch pretty much documentary length videos. Everyday astronaut makes crazy long and ultra detailed videos and he's got insane views on even the longest ones
That's Gymnopedie No. 1, composed by Erik Satie, in Kevin MacLeod's UA-cam Audio Library version. Dex was very kind to use parts of videos I had made before, and the background music at that part of his video gave it a great twist. In particular, I used that song for my second ever Cassini video (ua-cam.com/video/JT-0YM1EVoY/v-deo.html), and while I find it relaxing and a bit joyful, some people have told me they think it's a bit nostalgic and even sad.
Yeah, good idea. I'll do that. Part 1 is called The Invisible Sensor in the UA-cam title but in the actual video it's called Radio Science part -1. I'll change the UA-cam title to avoid confusion.
@@ReflectiveLayerFilm Cool. Lets hope my r/space post on reddit gets you some views. Your content is nice and not dumbed down and thus you are criminally undersubscribed.
How can the medium change the frequency of the radio signal? The sender will have emitted some number of peaks within some amount of time, so the receiver will see the same number of peaks within the corresponding (taking into account their differing reference frames) amount of time. I don't see how the medium can affect this. Edit:Ah, I see: the medium can affect the "effective distance" (the light travel time) between the spacecraft and Earth. That effect can change over time. This is essentially the Doppler effect (even if the spacecraft is not moving radially wrt. Earth).

You make great informative video's with nice animations. Must cost you a lot of time! They deserve a million views.
Thank you so much. It does take a lot of time but creating the animation is the part I find the most fun.
Excellent video. I had no idea we could use radio waves for so much in terms of detection. As always, great visuals and comprehensive explanations.

Well done. You should have more views.
Great information. Definitely checking out part 1 now. Thanks!!!
Awesome, thank you! Part 1 is short and just gives you an idea how radio transmissions are used in spacecraft for things other than communication.
The animations are so good, and I love your voice! Dear UA-cam algorithm, please show these videos to more peoplle!!!
Thanks!
Thank You 🙏✌️
What is name of song in 1:16

Beautiful
Thank you! Cheers!
Did I miss part 1? I searched your videos for "radio" and didn't see anything marked part 1. Perhaps you could pin a reply with part 1?
Yeah, good idea. I'll do that. Part 1 is called The Invisible Sensor in the UA-cam title but in the actual video it's called Radio Science part -1. I'll change the UA-cam title to avoid confusion.

I just went and gave you an upvote on reddit too. This channel needs to be known

Yes, it's really the inference signal that has the frequency shift relative to the original.
