Sometime back in the mid 80s, I watched a pair of nighttime scientific missions launch from Virginia. They released gases into the upper atmosphere (or near-earth space, I don't remember) for experiments. One of the gases was barium, IIRC. I could see the exhaust plumes of the rockets as they rose into the sky. The released gases each separately filled at least 60% of the sky, green and purple, a couple of hours apart, then faded away. I was in a dark parking lot with binoculars - in eastern Pennsylvania.
Noctilucent clouds (here in Sweden) are seen every year, mostly in August, when we start getting back some hours of nighttime. They are definitely one of the most beautiful things you can see in the evening twilight. They look like something that’s spiritual.
I actually some noctilucent clouds for the first time while flying at 38,000’ over Bulgaria I believe. I was trying to explain to the guy I was flying with how rare they were. They were spectacular. 1st and only time I’d ever seen them…
I live only about 20 or 30 mi from the actual rocket launch site and I watched the launch and the second stage and all that and then I completely did not know to stick around for another hour and watch for the noctilucent clouds! thank you very much for this education and I'll do that next time!
Not a "weird bug" - uploads to YT begin as low res imagery & the resolution improves as processing continues. A few minutes [or hours] later the resolution options increases from the basic ones available. The exact timing is variable & it also depends which version you are watching, each major landmass has at least one version at their local data centre. YT Support: "When you upload a video, it will initially be processed in low quality. This process helps you complete the upload process faster. Once the upload flow is complete, your video will be available to stream in low quality, on a wide variety of devices. Higher qualities, such as 4K or 1080p, can take more time to process. While this processing happens, your video may seem to be missing higher qualities for several hours. Once high-resolution processing is finished, higher qualities will be available on your video."
@@nightjarflying Well no, the weird bug I was referring to was when you have Data Saver enabled... If you view a video (not a Short) and select a higher resolution, then Shorts will also playback at a higher resolution. However z if you view a video coming from a System Notification, then it auto-selects the lowest resolution possible. _AFTER THAT_ any Short you watch, will sibilant default to the lowest resolution. I do know the one you're referring to, but can't say I've encountered it happening when watching Shorts. _(more often than not, I don't even encounter it on normal videos; even those I click into from a notification, at the very least 720p is always there, which is the highest I bother using [even on Starlink where I have no trouble with even 2K])_ Sincerely though, thanks for taking the time to say that! I'm sure some folks will find it informative! ♥️
This is cool. We were in Disney world in Florida the other day and it happens to be near cape canaveral, so we got up at 5 and watched it. About 30 minutes afterwards we saw these erie ring shaped glowing clouds, which are probably nocticulent clouds.
Interesting when you mentioned that a lot of the exhaust falls back down. I've always wondered how much of the propellant/oxidizer from these launches is lost to space forever, and how much of it remains on earth. Does the molecular mass of each component affect how much is lost or kept, or just the time scale in which it takes to come back?
I saw that launch and my wife was blown away and now has become obsessed with SpaceX. Not a bad obsession IMHO. But I hadn’t known to look for these awesome clouds until now.
Well said. ps I appreciate that you did not change your voice for views. Most shorts annoy me. This one is good. pps I still hate vertical. Well maybe not so much anymore. Thanks
Hi Scott, I was at this launch right near the security gate. 60-75 minutes later I got some cool pictures of the rocket contrails. They look better then what is shown here. Let me know if you want them.
Hey! I wondered for a while if spacecrafts would be benefited from my idea: growing cyanobacteria in space, since there is enough sun light in the solar system, only a uv protector would be needed for the cyanobacteria to survive, and they would simply feed on the co2 that passengers could breathe out. As the cyanobacteria grew, they could be eaten or maybe… converted into biofuel. Surely this biofuel wouldn’t be as good as hydrogen, but if it is on a small satellite, it could may be enough to go back to earth… just maybe… could you explain why not?
Is there something specific that makes these rare? Where I live clouds that catch sunlight before sunrise and after sunset are rather common so is it some more specific for Noctilucent?
When the sky was brighter for most people thousands of years ago and they spent much more time looking at the sky.. they probably saw all sorts of unexplainable beautiful things like this or the northern lights or all sorts or crazy atmospheric phenomena that they attributed to gods or aliens
Love seeing these after launches. I timelapsed both of these over the last 18 months. One from near the Cape and one from Tallahassee. They're beautiful and our only chance at seeing these types of clouds at our latitudes. ruclips.net/video/0-7X9zbZDVA/видео.htmlsi=a0WHvVZmKTGVu-Z9 ruclips.net/video/uCdKSAUXSD4/видео.htmlsi=j1Lo1mpxdNmkujkb They get really neat when you can give it a few hours after launch.
Sure that the clouds are coming from the burnt fuel? To my understanding the rockets exhaust contains small particles (also choke) which acts as a condensation core for the water which is already in the Air. Similar to the „chemtrails“ of airplanes
The recent dramatically increasing direct injection of large amounts of water vapor from rocket exhaust into the mesosphere and upper stratosphere is almost certain to have significant and measurable climate forcing effects in the near future.
@@nightjarflyingNot sure we are talking about the same thing here, but animals generally don't give off any visible light, with a few notable exceptions of course. But the light emitted by these creatures is very dim in comparison with almost all artificial sources. The movement pattern also makes it unlikely for any animal to be the source, as their movements are rather erratic compared to the smooth and steady movements observed in the video.
@@Tealice1 The animals are moths probably & they are close to the camera. Lit by light from a building behind the cam or garden lighting. A couple of the flying lights change direction almost instantly in the way of moths, some other insects & insect-catching birds/bats.

very Enlightening

you actually. ?
yes Bozo
With Helmholtz clouds forming underneath. Lovely
I notice this too. An atmospheric twofer!

Great lesson Scott. Happy New Year old friend ! Noctilucent, who'd a thought a new word !!

As if i couldn't be in more love with space travel

Very interesting, I'll now be looking for Noctilucent clouds when there is a rocket launch a few hours before dawn. Thanks for sharing.
great catch!
Hi Scott, I was at this launch right near the security gate. 60-75 minutes later I got some cool pictures of the rocket contrails. They look better then what is shown here. Let me know if you want them.
Noctilucent clouds occur naturally at the summer mesopause near 50 miles (80 km) not 50 km.
Would that be the summer solstice?
I've seen rhem created by rocket launches in Russia as well. They are quite unique for sure.
there also seems to be thoss wave-like clouds in the foreground of the noctilucent clouds
Its the electromagnetic field of the upper atmosphere that is ionizing the gases from the rocket and making them glow.
HULLO, Scott Manley here! And today we're looking at ROCKET CLOUDS

Noctiluscent clouds? Scott you are definitely a space nerd from the 4 dimension 😂
Aye.
rocket science and meteorology info all at the same time :)
Oh boy, wait until the chemtrail people hear about this lol
Genuine question, wtf do those people think a chem trail is?
Ok. Thats cool.
When the sky was brighter for most people thousands of years ago and they spent much more time looking at the sky.. they probably saw all sorts of unexplainable beautiful things like this or the northern lights or all sorts or crazy atmospheric phenomena that they attributed to gods or aliens
Nah, that’s a dragon!
What's that steaming in the lower right?

Beautiful nerd.
And now to listen to Noctilucent by I Built The Sky
Soo are you saying every rocket is also a small weather machine.....?
Sure that the clouds are coming from the burnt fuel? To my understanding the rockets exhaust contains small particles (also choke) which acts as a condensation core for the water which is already in the Air. Similar to the „chemtrails“ of airplanes
is there a house burning there
Great catch!!!
How could you see the rocket in California if it launched in Florida? I am bad at American geography, am I missing something?
He said it launched from Vandenberg, which is in Santa Barbara, California...
@@MyCami95 oh thank you so much 😊
awawawawa
Let’s stop global warming with rockets :)

You recorded a literal horizon in a vertical orientation?
He's not trying to show the horizon. He's trying to show the interesting bit. Y'know, the rocket. That thing that travels, y'know... vertically.
@@boatrat He isn't showing us the rocket, he's showing us the clouds created by the rocket's exhaust.
Several objects flying around in this video 🤔
They’re called airplanes.
What are all the other lights moving about in the sky? They don’t look like aircraft. Perhaps UAPs watching the launch and deployment?
No! It's insects [such as moths] or possibly birds/bats close to the camera
Not sure, but the camera seems to be pointing at the sea, so I'd guess that those lights are ships.
@@Tealice1 No sea. There's street light, house lights & I think some cars. The moving lights are all insects & other animals.
@@nightjarflyingNot sure we are talking about the same thing here, but animals generally don't give off any visible light, with a few notable exceptions of course.

Flat earth debunked. Again. :-D
So they are man made clouds... fake?
Wdm
maybe don't upload in 144p next time, bub
Check again later on. RUclips will have processed the video further and higher resolutions (like 1080p) will be available.
