Sometimes it feels like space channels are all repeating/rehashing each other, but this video feels wholly unique and inspired. In general, that's something I appreciate specifically of Astrum content, but this one especially

The animation they did of Cassini entering the atmosphere always makes me tear up a little.

Long Live Cassini

The photo of Saturn back light from the Sun is just so stunning. Both from it's beauty but also it's the first time we've ever seen Saturn in it's entirety from the back looking towards our Sun. Breathtaking.

Seeing Saturn through a telescope for the first time is an experience you don't forget. Even with 50X magnification it still feels like you're observing an ant-sized object, which puts into perspective how far away it is. But you can easily see the overall ring shape and just barely see the shadow of the planet being cast onto the rings.

I had no idea the rings of Saturn were such an incredibly dynamic system

Cassini-Huygens will be forever remembered as the gold standard for space exploration missions. It just went _so well_ as to almost be unbelievable. The entire thing was a triumph and everyone involved must be so proud. An incredible achievement and has scientific value and impact that can't be overstated. I do hope we can recover Huygens one day and put her on a plinth in a museum.

If I ever find myself feeling insignificant in life…I watch something like this and feel even tinier and more minute than ever before.

22:57 the though of the last "thoughts" of the Cassini being that of confusion and panic, wondering why it was tumbling and spinning out of control, desperately trying to stop, will never not make me cry.

My uncle worked on Casini. He is very proud of the machining work he did.

Alex I love your work, thank you so much. It blows my mind in the best way. You do what NASA's online presence (it seems to me) has always failed to do: you present it to us in a completely engaging and awe-inspiring way. Keep up the great work and keep inspiring us.

The faithful steadfast little space vehicle went the whole distance for us. The glory of the people who created it will live on so long as there is history. There's good cause for tears of pride and joy. Thank you Astrum.

You're able to fully convey the astonishment, thrill and utter beauty one cannot but feel when looking at our marvelous Solar System. Thank you Astrum! A very useful endeavour and an eye opener for many!!!

6:15 that tiny, blurry, hazy picture of Titan’s surface, is one of the most incredible images ever taken…😮

This was one of the single greatest astronomy videos I've ever seen. Please make more.

I had closely followed the Cassini mission for years. I saw every photo released and read almost every artical about it. I felt really emotional when it was announced that Cassini mission was coming to an end.

It's impossible to say one is more remarkable than the next but the Cassini-Hy mission is quite possibly the most beautiful. Capturing the most spectacular portfolio ever created in the history of mankind.

The way you explain things is amazing, and I love how often you seem to cover a topic very few creators of similar quality have

Galileo would weep if he could see these formidable pictures superb episode, Alex. cheers!

Thanks for summarizing this and making another absolutely breathtaking video. Learned a lot about Saturn today.

Never wanted this video to end. Just an amazing compilation and voice over.

It makes me sad not to know if this kind of discoveries would be made again in my lifetime or at all. But at the same time, being alive at the birth of spacetravel and opening a window this huge to the universe and how it works kind of put´s me at ease, haha. And on a side note, with Carl gone, in someways his poetry and masterful comunication skills are still is engraved and alive on us. Astrum has kept that Sagan quality I´ve come to miss so much, alive.

What an incredible video, thank you Alex! Your content is always such an informative pleasure to take in :)

Alex, you have painted an extraordinary portrait of Saturn, my favorite planet of the Solar System, outside of Earth. Not just because of it's beauty, but also because if it wasn't for Saturn's gravitational effect on Jupiter 4 billion years ago, there probably would not be 4 rocky planets, including Earth, orbiting the Sun. Instead they would probably be rogue planets ejected from their orbits to roam in cold, dark interstellar space and the Solar System would have a hot Jupiter. It makes me shiver to think about it.

My lovely Cassini! I look at the photos it has sent from Saturn system again and again every day. Thankful to the team that built it. Also to you for the videos. And Alex, When i first subscribed to your channel, you just had 100k followers or so. Look how big it is now! Spreading science through the dump of UKposts. Love from Turkey!

Yet another truly astonishing video. Thank you! ❤

This is the best space video I have ever seen. I knew none of this. I had gotten bored with channels that focused on space because It was all the same stuff I already knew or had seen. But I couldn't take my eyes off the screen. I just kept imagining I was sitting on a small moon rotating around Saturn's rings like you said. The pictures of the propagating waves in the rings blew my mind

I said WOW out loud like 20 times during this video. Absolutely amazing. Thanks for sharing!

This is my favorite video of the year! So interesting! You really took me on a journey to Saturn 😊🪐🪐🪐🪐🪐

NASA really was like “some of you may die, but that is a risk I am willing to make.”

Amazing! I've heard the stories before but to have it all summed and explained through your eyes was very beautiful!

Many, many goosebumps and tears here. Astonishing! Congrats for the video!

Tremendously fascinating video, thank you for sharing all of the beauty

You're such a fantastic story teller. I can't believe I got weepy as you described Cassini's final moments...

Brilliant video. Very informative and I'm grateful to hear a nice, clear commentary, spoken with enthusiasm and wonder at what was being described. Thank you.

Fab! A great summary of the mission! One thing that struck me was the rapidity of Saturn's spinning. Imagine a planet that big rotating every 10 & 1/2 hours. 5 hours day, 5 hours night.That's churning around incredibly fast!

Do not fear, Astrum is here! Love your videos as usual, Alex. Great job

The Cassini-Huygens Project represents the absolute best in our collective endeavor to understand.....the universe....everything. This US taxpayer tips his hat to NASA, ESA, and any other agency with a hand in this, Well done, ladies and gentlemen. Well done!

I love astronomy and after watching this extremely well-done video, I feel more educated about Saturn than I have ever been before. Just fabulous. I have shared it. Thank you so much!

you all do an awesome job. this is one of the best cosmic channels on you tube

These images are why we need poets and writers. I do not have words to properly convey the awe and grandeur I feel

Giovanni Cassini would be in awe if he saw this.

Many thanks for the outstanding and unique video materials as well as bright and understandable audio explanations. Accept my huge respect.

Thank you for this great summary of the Cassini mission. Here in YT, i also watched two videos posted by NASA with the technical details of the mission. Obviously the focus of the videos is on the Cassini probe itself and the people who managed it, but they are worth to watch if you have time to spare. Thank you Mr. McColgan once more. Greetings, Anthony

nothing short of incredible

Why did watching this make me so emotional rofl I'm so embarrassed

All I can say is WOW! What an amazing video you've made. Thank you and keep it up!

Wow! Thank You for an exceedingly detail comprehensive summary of Cassani mission and data dissemination and photographic renderings, quite awesome worthy of a study in some classroom. God Bless you my friend, Ken

Woke up to see a new Astrum video, best morning so far

Maybe we won't get another free ride out that far in the next 600 years, but I can't believe that we're not gonna come up with some other way to get out there before then. I seriously doubt these are the final close-up images we will see of Saturn. I love your work by the way!

Great Job 👍 Thank you for this. Superlative and sublime.

Thank you for this deep dive into Saturn. As much as Saturn seems (to me at least) a chaotic place, its beauty is unmistakable. My line of work provides a word you touched on - that we are fortunate to be here at a time to see and explore Saturn and its receeding rings. Indeed, we are. The word we know as "blessed" translates to the word "happy." How appropriate. Engineering and art have their own beauty and testify to that fact to those who are blessed (happy) to behold them. I, personally, marvel at the vastness and variety of creation. So much to study, so much to explore, and so much to enjoy.

Wait.....the Rings are a spiral groove!!!!! It a massive Vinyl Record, I wonder if it has data encoded on it, or maybe a kick ass banger of a music track. A bit like the gold disc we stuck onto Voyager :D

It's absolutely mind boggling the mathematics and ingenuity involved to slingshot a satellite from planet to planet.

most excellent, brilliant, insightful and extremely educational video, Alex. many kudos

I love how much depth went into this video, i love the Cassini spacecraft because it was launched the same year i was born in (i was a couple of months old) and when Cassini was sent to it's heavenly grave among Saturn's atmosphere i was 20 in 2017, and it was my best year i had. I always loved Saturn as my favourite planet, its just a mysterious and beautiful planet, so thanks to the people who built Cassini, the people who launch and to the people who received the data and of course to Cassini spacecraft that did a fantastic job for 13 years, collecting the data of Saturn and all of its system. Thanks You 😊😊😊😊

Video suggestion/idea. What would happen to the earth if it became tidally locked to the sun? And what time of the year would you pick for the earth to become tidally locked to the sun if you could in hopes of giving humanity the best chance at survival? Personally I would pick the longest day for the southern hemisphere with the Pacific Ocean facing the sun. Water would have a better chance of moving heat around the planet and we would get to uncover the land beneath Antarctica. You'd also have multiple large land masses ( Asia and Australia on the east and the Americas for the west ) that would remain on the edge of day/night which would end being where all of us would live.

Best and most interesting video ever.

I keep watching this documentary, this must have been the 4th or 5th. Never ceases to amaze me. Thank mr Alex!

Absolutely fantastic presentation. Your talent for story telling is awesome. Thanks for sharing.

Pan is my favorite looking moon. It looks like a ravioli. Teehee 😋 👄

I'm fascinated with Saturn, especially the big octagon

What a great compilation, so beautiful ❤ thank you!

Such spectacular imagery of saturn and its moons, and this video does an amazing job of showcasing the stunning images that cassini-huygens took. I've long thought of Saturn's colours as being uninteresting compared to Uranus and Neptune, and only its rings and moons were of any interest to me, but this video completely changed my mind, Saturn is a spectacularly beautiful planet with so much intrigue and mystery.

a 20 year old satellite, after travelling through open space for 7 billion km not being serviced or repaired a single time, no updates to its software or hardware - was able to send high resolution images 7 light years back to earth (it somehow also knew what to take pictures of and how to adjust it's aperature and zoom) while it was burning up through an atmosphere made of acid? but my phone dies in 4 hours and 2 inches of concrete is enough to completely cut off all reception. adorable.

Ah yes, gayseus atmosphere. gayseus hydrogen.

Thanks for another great video, look forward to many more!

I was a senior in highschool when this mission launched. And after it arrived at Saturn, I was so excited to see the images. I love when a NASA mission goes well beyond the original plans.

A rotating magnetic system may possibly find a way to act as either a generator or a motor. It can rotate more slowly (as it is not necessarily a solid) and generate a larger magnetic field, or vice versa. Physics 101. It is unlikely we have sufficient evidence to identify the unknown factor/factors*. The only mystery is our understanding. You are not alone. With you, bro. We do not understand either. 😎 * I have a feeling, but do not know, that this may share some similarity with the 3-body problem. Props for the beautiful images. Saturn is a Physics demonstrator.

Ever? Really? That’s clickbait but here I am.

this is the best video about the cassini mission I've ever seen. thank you

Watching the amazingly beautiful images of Saturn captured by cassini and then realising that this spacecraft launched waaaay back in 1997, gets my mind blown each time when i think of it. At that time i didn't even know the term "Astronomy".

Can you imagine if this title was about Uranus?

When the death of a confused space probe brings tears to your eyes

It frustrates me and leaves me in awe the thought of space in a literal sense, just an unimaginable amount of bodies of rock and gas floating around in an equally unimaginable and seemingly endless "space" going through phases of whatever physics are at play and we as humans most likely will never learn it all or even see things we haven't seen or could even fathom. We are a speck, basically nothing in the vastness of this space, a tiny fraction of time where we exist in it... The things we can't see or will ever see in person, the knowledge and understanding we will miss out on, the beauty and horrors we will not be able to witness to appreciate. Even simple things such as what would it feel like to be standing on the surface of another celestial body, how much colder or hotter is it than Earth? What would we see gazing up at space from the ground of another planet? Would the different atmospheric conditions make it appear different than how it does from Earth? What would it smell like if it was possible to smell in such environments? How would your weight feel? How far would you be able to see? Do things sound different? And of course, if there is life..how far along has it come? Is it visible to the eye, is it plant life? How old is it? Do physics just work in ways we have never seen before on other planets? Feels so unfair to have such an immense expanse around us just to not be able to experience even a decent fraction of it.

How extraordinary that even after all these data are gathered in that we still have so many questions regarding this wonderful world. Thank you.

We should have one probe like this orbiting every planet in the solar system

Oooo. long video, exciting! Thanks!

Thanks for this incredible video. It must have taken an amazing amount of research and time to stitch together.

Great stuff. That bit about the lagging ripples at 21:00... so beautiful.

BIG THANKS to Cassini and all her crew! Awesome work :)

The only problem I have with this channel is the click bait video titles.

Counting ripples in the rings! We just love counting rings don't we? Can't seem to help ourselves from coming up with some new way to do it. 🧐🧐 It is so amazing how much we already know about Saturn. Thank you so much for a movie of Cassini's plunge!!

Something I really appreciate about this video is that the Computer Generated Images are labeled as such. Unfortunately many media sites do not make this distinction and end up being very misleading with their information. Thank you for your integrity.

It's a bummer that they had to destroy this plucky little spacecraft. This thing has to be in the conversation of pound-for-pound spacecraft champions. Thanks for putting such a comprehensive video together about this *cough* stellar *cough* *cough* machine. I'll just slide out the side door now. Cheers!

Damn loads of porn bots in this comment section

This is for sure the best episode I've seen.

Another beautiful narration, Alex!

I remember watching its final plunge live (NASA livestream). Very sad moment.

So 5000 deaths from cancer is an acceptable risk for NASA! Isn't 0 deaths more acceptable? What a very nice organisation!

The narrator's voice makes me love this channel especially his tone so delightful and charming.

Amazing video Astrum - the soundtrack was really empowering

I just love the photos of the probe giving close ups of Saturn inside its ring system❤❤❤❤❤

This is one of the most underated Space video i've seen Thank you very much

Always fascinating to watch your vids....

Fascinating!

Right on. Thanks for sharing.

Incredible video. Well done!

Wow, so well produced. Wonder-filled!

Thank you for the video!
