comet facts space documentary
I was a volunteer looking for particle trails in the samples that were returned. I would look through the pictures at lunch for weeks. It was cool to be a part of the citizen scientist project.

You mentioned "a navigation camera"; there were actually two of them (visible in renderings of the spacecraft at 6:31 and the photo at 6:41). Those were dual star tracker cameras, which I helped design and write the software for. An amazingly complex and under-appreciated aspect of the mission. :)
Bless up yourself 👑
Tell us more!
Please tell us about it!
Did u twap a fart in there? 🥺
Let it be known.....I appreciate your work.
Your welcome.
I didn't remember this mission and found this explanation utterly fascinating. This channel is such a joy and has reconnected me with my earlier interests and career in space operations. Thank you!
Alex, while at University, I religiously participated in starduSt at home . Fantastic program. I was too slow to find the particles and so didn't end up on their publications but man was that a cool time.
The planning of those involved in the Stardust project really worked out perfectly and gave us new perspectives
Keep up the good content man! Really enjoy the time and effort you put in all your videos.
Amen to that! It's *SO REFRESHING* to have a channel devoted to actual *FACT* without abhorrent afactual *RHETORIC!*
My family was in Portland several years ago and went to their science museum. They had an exhibit about this mission. I found it so inspirational I bought a t-shirt that says, ‘We are all made of stardust’.
It’s wonderful to think we are not only connected to each other as species on this planet, but as small as we are in the entire universe, we are not alone. We are connected.
I volunteered for this many moons ago and traced several tracks in thin slices of aerogel. Pretty cool project.
This channel is a contribution to the people. Such great content.
Yes, we The People are grateful.
Absolutely!
Yo momma is a great contribution
Indeed, I am one of the people!
It’s not. It’s carefully crafted content, from meticulously selected footage and background music, to precise accentuation and intonation of every single syllable of the narration for maximum psychological auditory impact, so you will click like, subscribe and write this comment, so this ‘creator’ will earn money off of it. The information he presents here is all available on Wikipedia. useless video, good entertainment…
The level of genius that goes into sending out a man made object into the grand void of space and have it do such things like observe other objects and collect samples and then send those samples back to earth is mind blowing. I can't fathom the math and science behind all of that. Humans are truly interesting when you think of how we started out life living in caves and trees.
Thank you for sharing the stories, note that while you discuss glycine in a comet you show purines from a meteorite at 10:34. Though both discoveries were from the same NASA team. Also, the significance of the spacecraft’s final transmission was to verify that the predicted amount of fuel left was accurate-it was.
The sound at 8:31 is like one of the running/chasing sounds from 80s/90s cartoons
wow, i didn't know about this mission. really fascinating.
I love hearing all these details about missions I’ve never heard of. This channel has been a great find for the last 2 years.
S
I am in love with human ingenuity and engineering, the animation of the aerogel sample collector was truly something to behold
why do I get all emotional when a spacecrafts' mission comes to an end? These Brave and Noble explorers forever doomed to wander the cosmos, alone, cold, silent? Sometimes I imagine the view from these craft, how horrifyingly fantastic it must be!
Gonna b one heck of a collection in the future.
I was always the science nerd in school, college was genetics but I’m still fascinated by the content on your channel. Thank you 🙏
I'm glad I stumbled over this channel. It's jam packed with such incredible videos. I honestly don't think you've released a video that hasn't been well put together. I HATE text, have and will probably always be a visual/audio learner and I've learnt such an unbelievable amount of information here on the channel. You're videos have given me insight into things I never knew existed and consequently improve my knowledge on a massive range of different subject. I just wanted to extend my thanks and I hope you guys continue to release amazing content for the years to come. Wishing you all the best in life.
It was actually quite hard for them to scan for the dust particles, even once they'd done loads of imaging. They had a crowdsourced project where people could sign up to hunt for them in the images.
Elaborate? You mean because of the huge amount of particles trapped? Or the size of them
@@HankHill1 Both but mostly the size
Great info on this specific Mission! Had no idea about it but glad I do now! Aerogel is the future! Thanks Alex!
So I learned a lot from this video! Including the actual pronunciation of the comet's name. I'd never heard it out loud before, having only read one or two articles about the Stardust mission. And not knowing any context for the name - well, I assumed it was pronounced the same as the English word "wild"! I also somehow did not know there was aerogel on the sampling tray! It's been a long time since I read those articles, so I can't recall with sure clarity, but maybe they were more focused on the captured samples than the mechanisms of their acquisition.
Very good content - thank you!
You experienced the "Calliope Effect" or the effect of reading a word and thus not being certain of it's correct pronunciation :)
I too thought of it being the English wild...and from what it discovered...it was💌😁✨
@@ChristophersMum Its almost like the person providing commentary has an accent that makes their w sound like v... 🤔
In German, W’s are pronounced with a V sound
Paul Wild was the Swiss astronomer who discovered the comet, hence the German pronunciation.
This was a good, solid description of the experiment. Well done. I followed it through its entire lifetime, and you covered all of the highlights! From the invention of aerogel, to the successful recovery of the panels of it, to what was found inside, the story is a fascinating one, and one which you did justice. Thank you!
Amazing content!! Why is this the first time I've heard about these missions. Thanks so much for your high-quality videos!
This was SUCH a cool video!! I had no idea about this mission nor images and physical 'items' from the comet that came back to Earth. So cool, man.
I discovered the largest track found on the collector! I still have the print out of my discovery :)
Your videos are so calming to me, I use them to fall in love with the universe and drift away into my dreams! Thank you, keep producing my friend.
Clues for the origin of life by the Stardust. Stardust for the exploration of comets ended up providing clues to something more enigmatic than the comets itself.
I *thought* I knew a thing or three about aerogel.
I cop to it: Mind officially blown. Great informative video!
Already subbed and alerted, but sharing this with similarly-minded aerospace geeks (retired from Boeing, Beech, XCor, Bigelow, et al)
"For Christmas, could Santa help me find the 'Sounds of Space' album that includes that stoccatto crackle of comet dust impacting our brave little toaster?" Thanks!
@@WilliamRWarrenJr , I'll talk to Santa Claus & see what I can find out. he he. v
That Aerogel particle collection apparatus is one of the coolest gizmos of all time!
Love the video! As a whole, this channel is fascinating and I look forward to the next gem 👍🏻 good vibes and good fortune to you and yours!
Simply fascinating, way to go NASA!
Keep up the great content, Astrum.
Thanks for the info. Many of these missions vanish into obscurity and you never hear what came out of the science because that doesn't sell soap.
I had no idea about this mission! Absolutely fascinating. NASA engineers are brilliant. Thank you so much for these beautiful videos.
Awesome I really love this channel and this content
Take care and have a great week 🌍💯
Another great video! Thank you for sharing, Merry Christmas to you and all!
Love this channel. Love the soothing space like background music and definitely his accent and voice. So good!
I agree. Really enjoyed the music in this video ❤️

I was at the Stardust launch and also just outside the clean room at LPI and am thrilled to see this wonderful video related to the mission. THANKS! I am also a Solar System Ambassador with JPL and do presentations and activities to help kids and families learn about the wonderful work NASA/JPL do.
Comets have the ability to super offically terraform a dead planet, based on size. It also may do the oppisit to a living one, the dust remain has many streams of resource, as demo in this vid.
Thanks for making such fascinating science accessible for us lay people!
I remember this event. I am also old enough to remember a Sci-Fi movie called "The Andromeda Strain" where the satellite with samples, collected from a meteor in Andromeda, crashed in the American South West and released a toxic lifeform that crystalized the blood in humans. I am glad THAT didn't happen.
Great presentation!
Best channel on UA-cam hands down
Amazing!!! Brilliant!!!
I really appreciate the time and effort it took you to make this video ❤️
"NASA discovers" and a picture of a Pyramid

7:33 oppertunity missed: you should have said "the surface of the comet was unexpectedly wild". C'mon...
I'm firing my writing staff immediately
@@astrumspace Good. xD
@@sizanogreen9900 Except for the fact Wild is pronounced vilt....
@@Nitro4x4 buuuuh! nobody likes people who spoil the fun with facts.
@@astrumspace , Ha ha. I fire my editor (that'd be me), all the time. Happy Christmas. v
Jelly is just such a satisfying material. Who would've thought it also has uses on a spacecraft ;)
Or jello shots
@@babyoda1973 I like how you think.
it's a thing of beauty is science and Astrum is an artist painting wonderful pictures for us all to see, thank you so much.
9:02 Cool view of the Pleiades star cluster in the return video from the DC 8 observation aircraft.
Fascinating, Thank you Alex!
Universe is mysterious.
Imagine 200 years from today. What possible innovation and world would look like.
Think this way and you will discover something greater ❣️❣️😍
Thank you for your hard work.
amazing insights. keep on! :)
Top grade presentation and all new info for me. Much appreciated, friend.
I was happy to support you by signing up to Magellan TV, but tbh it's a bit disappointing. Glad I had a discount!
Fascinating. And also interesting.
Thank you for your service!
he knows how to make engrossing content. he makes this look so effortless. he’s always on point. even videos I’m not interested in, I wind up being interested in. he always takes you where you want him to take you. and the classic words “I’m Alex McColgan…” should go down in history with the same reverence of those from casablanca and the gettysburg address. thank you sir(s) (and ma’ams - whoever contributes).
that said, this only thirteen minute video had an inordinate amount of ads. constant. I hope perhaps my UA-cam was just glitching out. because it was really over the top. imagine the most ads you’ve ever had, and at least half of those being unskippable, then multiply that three or four and that’s roughly what I was fed during this. but I’ll reserve judgment and give the benefit of the doubt unless I see it again. really made it almost unwatchable. Still, thanks!
I really enjoyed this one, Alex. The Stardust mission seems so long ago now. Just before Stardust, NASA's Genesis mission was to collect solar wind particles. That collector array used a variety of complex wafers made of gold, silicon, sapphire, etc. But the sample return capsule crashed in Utah in 2004 because of an accelerator installed backwards.
I worked BOTH Stardust and Genesis. I was in charge of integrating the Stardust Sample Return capsule Avionics Box (the one with the accelerometer in it).
I even found a flaw in the Genesis Avionics box that SHOULD have led them to find that the accel was in backwards but they missed that opportunity.
FYI - Stardust launched FIRST and got back LAST
Your channel has helped me to keep me busy in 2021 thanks
thanks for yet an amazing production!
I remember when the video was titled "Why they put aerogel on stardust."
That thumbnail remembered me of an unstoppable darkness...
Woa the topic itself tells something ❤❤
Very interesting Alex! TFS, GB :)
What a great documentary. The animation of the aerogel collector was a highlight, as it made it easy to imagine Stardust out there, doing the good peoples work i.e. increasing our knowledge and understanding of this awe inspiring universe. Who'd have thought a wager between colleagues in the 1930's would result in us now having samples from a comet? Wonderful stuff.
Thamks Alex, absolutely fascinating. Best of the season to you.
Another great video, as always
I don't see why I need Magellan TV, when I can watch your videos instead :-)
Couldn't find anything similar planned with a quick search, but it'd be cool if one day we sent out another stardust collector to a comet we know is extrasolar. I bet we'd learn something cool for sure.
Stardust retrieved SOME "extra-solar" particles during the mission.
During Cruise they exposed the BACKSIDE of the grid to a known flux of interstellar particles.
I never heard if they found any or not,
Hey Alex!! Will you make your future videos in 4k? BTW love your videos from India
Your understanding of the limits of the audience is very very impressive. Not being patronised guarantees return views. Thank you Astrum.
I'm so middle aged my first thought was: Imagine putting that stuff in your wall cavities, you'd save a fortune!
Amino acids on a comet ! Interesting. Consider this: A seed does not look like what it produces; an acorn does not resemble an oak tree, nor does an egg resemble a chicken, nor does a sperm cell resemble a human. Could it be that comets ARE the seed of life?
Brilliant scientists and engineers at NASA.
Incredible stuff, great video.
I recall a mission that captured cometary particles, then on re-entry its parachute didn't deploy and it crashed somewhere out there. They still managed to recover some particles, but not as many as were captured. But you say "everything worked" for Stardust. So what am I thinking of then?
Genesis sample return failed to open its parachutes.
@@whfrazier Thank you.
@@whfrazier Yes thank you. I had the exact same memory as Eben King. Thought I was going crazy.
I remember the news reports saying it crashed.
I remember following this probe way back in the day. I seem to recall that it was also one of the first probes to use an ion thruster as well
Good Video mate, you explained everything very well.
What a pro at stretching out your video with vaguely related information related to the title.. I was able to get to answer I need in two minutes with a google search. Hope the money is worth it.
And this is why Omaumua was so interesting; it was the first confirmed visitor of out of the solar system.
Such great content to watch. Really enjoyed binging our current progress up in space!
Another video that contains alot of very useful information 👈
Waiting for more videos 🤩
I remember in primary school learning about this craft and it's aerogel catching device.
Wow that's some nice air gel I wished I had a bunch of it as well of an insulator is it is I could insulate my house with it and you can even make a furnace with it to insulate the inside and that stardust I think a lot of that stardust that they collected was from inside our solar system that it had picked up as it is flying through our system
Yess I've been looking for info on the probe star dust
This is going to be interesting.
It was and great narration.
Thank you.
We had a probe visit a comet and then shoot samples back to earth? Samples ingeniously collected with aerogel? I never knew of this one.... thank you
Wow star dust mission was years ago.glad they are still studying the materials
Amazing...Thanks for the Mind Boggling information...Expecting more !!!
Another great video, fantastic! Thanks for sharing!👍🏻😎
mr,Wow!so super viddeo-work!)
D2 players really just got a heart attack from your thumbnail, gg!
Beautiful story and video. Star dust. Amazing
I am amazed how we have learned how to send things from space safely back to earth. Yay, science!
When speaking of amino acids, DNA nucleotides are shown in the animation instead. Just clarifying that distinction for viewers.
I helped build, test, and Launch Stardust. I have a piece of the aerogel from the Engineering Development Grid that was installed in the spacecraft through environmental test.
It even has a 'carrot track' in it from the testing at the hypervelocity vacuum test range.
I also built, launched, and operated Deep Impact.
It was the mission that was to punch a hole in Comet Tempel-1 and get a picture of the impact crater.
That mission failed to get the picture but STARDUST came along a couple of years later and got the picture FOR US!
YAY!
Thank you for your brilliance on this project. It must have kept you excited each day while working on it.
@@lindarocco9974 - I have also helped build and launch, Mars Global Surveyor, Stardust, Genesis, Deep Impact, Kepler Space Telescope, NOAA-20, and just a few weeks ago the IXPE X-ray telescope.
@@stuartgray5877 Thank you Stuart for your amazing contributions to science. You obviously studied for many years, and gained incredible experience in your field. What is your field of expertise, Optics? I'm sure you could blow my mind with a tale or two from your daily work life, no matter where you located.
@@lindarocco9974 - " What is your field of expertise, Optics?"
My degree is in Electrical Engineering, but my job has always been an Aerospace Test Engineer. So I write the procedures to assemble and test the spacecraft from inception to Launch. So the hands-on TEs tend to know more than many of the engineers that helped build it about how it behaves.
So they often use me to assist for a while after launch to get everything working.
I do currently work for one of the most advanced Optics companies in the world. The same one that fixed the Hubble, built the Kepler space Telescope, and most of the hard part of JWST.
@Astrum I'm no scientist, but when I read the title of this video I got excited. I got excited because I thought it was going to be about our star (The Sun) emissions of dust. I know that the Sun has a dust shell which it periodically blows off through SME's, super flares and mini-novas. So my mind was going in that direction, hoping that they have found 'life' in our Suns dust. I know there are huge quantities of space dust being observed by astronomers everywhere for quite some time. So my mind was hoping that this space dust was a form of early life that was intelligent, organized, and perhaps a blueprint of simple life that has been dispersed everywhere. I was fascinated to learn this was actually about the Stardust Mission. This was an excellent video. Thank you.
When my class visited the Science Center we did a simulation on flying a probe with aerogel through a comet trail and we got to see aerogel in person. It's hard to believe it's real. Very fascinating
Why that thumbnail's object have the exact same shape as one of them dam black pyramids from destiny 2
When you say that something in space is going X kph, what is that relative to? The sun?
I agree. I doubt the particles were going 23km/hr relative to the aerogel. I dont think any material could slow something down from that speed to zero in that short of a distance. Those speeds are probably relative to the sun, which the spacecraft was also doing. It's like documentaries during the apollo era when they talk about the difficulties of docking two spacecraft "at 17,000mph!" Well yeah relative to the earth they were that fast but relative to each other they might as well have been stationary. Not that these aren't amazing achievements, the reporting is just misleading.
@@peterw1534 He never said it was going 23km/hr relative to the aerogel. When a speed is given that's just how fast it's moving through space and it's not comparing it to any other object. He didn't give a speed for the spacecraft but the video showed the spacecraft approaching the comet but moving in the same general direction but it's hard to tell how it's speed compared to the comet. Since they weren't trying to match speeds they had to have a way to capture the dust moving at a different speed.
@@mikeyoung9810 That's the point. All videos imply omg it's going sooo fast how are they able to do this?! Turns out its relative
