- On 15 October 1997, NASA's Cassini orbiter embarked on an epic, seven-year voyage to the Saturnian system. Hitching a ride was ESA's Huygens probe, destined for Saturn's largest moon, Titan. The final chapter of the interplanetary trek for Huygens began on 25 December 2004 when it deployed from the orbiter for a 22-day solo cruise toward the haze-shrouded moon. Plunging into Titan’s atmosphere, on 14 January 2005, the probe survived the hazardous 2 hour 27 minute descent to touch down safely on Titan’s frozen surface.
This narrated movie, created with data collected by the Huygens Descent Imager/Spectral Radiometer (DISR), depicts the view from Huygens during the last few hours of this historic journey.
This new version of the movie uses updated DISR data and was released on 14 January 2015 on the occasion of the 10th anniversary of Huygen's landing on Titan.

Science makes me sob in awe and joy sometimes.
Why are people trying to "disprove" this as real footage? It was never meant to be real footage, just an animation based on photos and renderings to show Huygens descent
Where is the real footage?
@@sylvesterdakatt3150 I saw it in black and white, I can’t find it on my computer, if I find it I’ll show it to everyone.
They need to watermark all these new missions and space footage, as its become impossible to tell and i find it kind of annoying that they dont say it up front a lot of the time. Is there real footage, as im super interested
It IS real "footage", made from assembling and stitching the thousands of short-interval and narrow angle images from the probe's cameras through the descent and landing. It is not a 'rendering".
Facts!!! I do wish they said that right away in the beginning though, to let all the slower folk know. I personally saw this a while ago and looked it up. Funny how you find things out when you actually try lol
Wonderful!
Every time I see a picture of a planet or a video, my brain automatically thinks "photoshop. Fake." Because it's so crazy to think that we can see something so far awat, so clearly
This was just animation not the real video but the last picture was actually real you can even see other planets from the telescope clearly
yeah like a video call a mile away, impossible.
@@grovestreet9165 No, it is all real imagery. Why is tat so hard to believe?
@@grovestreet9165this wasn’t an animation, it was a video that was put together by stitching many pictures that the probe took
telescope in space cuz
Soooo google maps has already done titan
Where’s the nearest gas station?
No need for gas stations, there are surface hydrocarbon lakes!
You're looking at the gas station of the solar system, dude!
Looks like Space Engine. 😂
I spotted Waldo on the left.
There you go true science no fiction Beauty..
Wow
Can I use this video for my CZcams video?
Anybody know where (or if) I can find this cover of Beethoven Piano Concerto 5 that Debbie Hu made?
Wa-tur-ice rocks!
I can see my house!
I want to watch the actual footage of the landing and passing through atmpsophere.
You wouldn't want to see pictures passing by like a powerpoint presentation. And i'm pretty sure you'd call it "fake".
This is the actual footage.
i wonder what will happen if someone light a match in that atmosphere?
No oxygen, so nothing.
@@michaelclarke1986 but methane is there..a highly flammable gas
@@ashishbhatt3467 that actually doesn't matter. The chemical reaction to ignite methane requires oxygen.
@@michaelclarke1986 yeah because if it has oxygen it would already have burned
very scientific
😳😮😶 ♥️
I calculated a lot less atmosphere. 26 km/h at 12 km. That is very dense. Nitrogen, helium, oxygen, there are hydrocarbons.
Is any of this photoshopped? 2:25 looks a bit like zooming in on an image.
Original Hyugen didn’t take a video it sent pictures and this is an animation based on those photos that Hyugen sent
@Jan Brady Because that's not the point of this video, the author wanted to approximate what the landing could've looked like. You can find the raw images on the web photojournal from NASA.
@Jan Brady on the side of the screen during its decent was a real picture
Seth Rogen narrating?
check out the astrum channel, some very interesting and informative videos explaining loads of stuff like this..
NASA Use what is called a giant "Long Focal Fresnel Lens" The focal point is so far away all you get is heat and warmth aimed through it from the sun on mars,,,no need for heaters just set up thin pieces of plastic giant "Long Focal Fresnel Lens" folded up in a rocket... I really could care less for getting credit i am a space nut not a narcissist...3b
Is fake, no real video. I'm looking for a real video of the descent, I saw it before, it's black and white made up of real shots, if anyone has a link.
There are no videos recorded by Huygens's camera. This is a computer simulation of how Huygens could have landed on Titan. Also the video contains real images by Huygens stitched together. Hope you understand.
there is a real image
They say titan has liquid methane oceans.THE ONE VIDEO WE GET HAS NONE OF THAT WE JUST SEE ROCKS!! WHAT THE FUCK
it's cause it didnt land in or near the oceans.
@@hubbletrubble7875 yeah but why
Bro it’s the second largest moon in the solar system. That’s like landing in the middle of Australia and going “hey I thought this planet was 71% water!”
@@markanthony4546 are u telling me you'd rather see more rocks than a liquid Ocean on another planet why waste billions of dollars to see the same old shit,they go on and on and the liquid Oceans on titans and the H2O polar caps on mars and you're gonna sit here and tell me your satisfied with seeing rocks
@@andreburruss11 I don’t think you understand that when landing on an alien planet, you can’t be picky about your opinions. Also how TF was a probe meant to land in an ocean? That adds way more complications.
This is a computer game lol
this cant be real. there is no depth. clearly the images are blurred out when its closest to the surface.
This is reconstructed data. It is not the same as a picture taken from your camera. The video was made using a series of pictures taken at intervals much larger than the 1/24 seconds your camera does. It's similar to how Google Maps' Street View is reconstructed. Ever seen your street on Google Maps? Is that not real too?
Of course it's not real. It is an animation on a screen
First of all, Please explain why there are blurry patches with absolutely no detail at all. Does no one see that? Not only that but there is an impossibly sharp boundary between the clear and blurry part which suggests a computer image of some kind. It's just so pointless I don't see it as proof an hoax since no one would be that careless in making some hoax.
The probe did not record a wide-angle video in the visible spectrum, but it did record a series of still images at different heights of slightly different locations. I assume that for this video these images were carefully aligned to match a CG animation of the descent for visualization purposes. I think it's more honest to keep the blurry patches instead of making up details for the places no camera was pointed at.
I found some information on the camera equipment here: sci.esa.int/cassini-huygens/31193-instruments/?fbodylongid=734
I also recommend looking at the Twitter profiles of @SpaceGeck and @_TheSeaning. They do this kind of compositing masterfully and regularly.
So, why can NASA rarely provide actual footage instead of a rendering of what they claim to do?
@@peacealien37 Because video processing power requires transmission tech that would add a lot of complexity and weight to the mission. Also keep in mind the mission began in 1997, not 2017. Space is massive, and shit takes time.
The probe had a narrow-angle, monochrome camera that pointed in a fixed direction relative to the probe as it fell and rotated. The idea was that the probe's rotation would effectively scan the region around it, but the rotation turned out to be much faster than predicted and in the opposite direction, which produced somewhat jumbled results. The image quality is not great because of the heavy compression required for the limited bandwidth back to the Cassini probe, which relayed the signal. Also, about half of the images were lost to a communication error. So what we have here is a reconstruction based on piecing together the individual images that were available. The imagery is real, but it's been assembled into a CGI simulation of the descent. The colors are also a reconstruction based on other sensor data.
orion37 Titan gets 0.1% of the light Earth gets, so you can't exactly take a normal 'video'
the earth and the moon isnt that nearby. sadly i think this video is a fake ;/
@@williamony7080 No, that really is imagery from the probe's camera of the Earth and moon passing over the disc of the sun. Not sure what the guy means by "nearby" - it is a telescopic view obviously.
looks fake AF
It's some images made into a animation of sorts, it's not a video.
Haha, fake. It is simulation again.
It's a simulation based on real images, are you stupid or what.
Noo i know its a computer simulation but its made by stitching real images toghether.
Too fake. Heavily suggests that real footage doesn't exist.
It's picture's.
Bruh how dumb are you lol
Idiot - read the description - its constructed animation made from the series of still images the probe made while descending, They even tell you that!
