Other Worlds, Episode 3: Titan

Titan, a moon of Saturn, is the only object in the solar system besides Earth with liquid on its surface, making it relevant for the search for life beyond Earth. But instead of water, methane and ethane make up Titan’s rivers and seas. Join scientists as they explore Titan with NASA’s James Webb Space Telescope and develop the forthcoming Dragonfly mission, which will send an octocopter to this fascinating moon.

Sagan, boyhood hero of mine. There’s never been another like him.

[@RussBayne]

I was 14 when Cosmos began airing on PBS. Every episode was an epiphany. He literally introduced me to the Universe.

[@TG-nd9rj]

I first learned about JWST via SciShow (thanks Green brothers!) when I was 12 years old, and eagerly ate up any updates we got on the project. I was 22 when it launched on Christmas morning and I just wept on my couch watching it take off. I can't imagine how much excitement the team was feeling, having been waiting for that moment for much longer than I did. The first images were breathtaking and it's just gotten better since. Thank you so much for this look into your work!

[@LoveatFirstHike]

Wow, that’s awesome! I was in my early-mid 20s when I discovered Sci Show back around 2011! Time flies. I was eagerly awaiting JWST as well, crazy to think it’s been up there a couple years now

[@Billy-u6m4h]

Your comment doesn't make any sense. Please help me understand. How old are you currently? When was the James Webb space telescope launched? How could you be younger when JWST was launched than when cassini was launched?

[@TG-nd9rj]

​@@Billy-u6m4h My comment has nothing to do with Cassini. You haven't watched through the whole episode. It starts by explaining what we learned with Cassini, and then goes on to explain NASA's plans for exploring further using JWST and a new mission. JWST launched on Christmas Day in 2021, I was 22 years old. I'm now 25.

[@Billy-u6m4h]

@TG-nd9rj thank you for clarifying that for me.

[@brahmburgers]

I'm a science and nature guy (no religion or metaphysics), and this is a great video, thanks. It's great to see the genuine enthusiasm of those involved with those pathfinding projects.

[@JasonFreedman-e9j]

Video Editor: Please (PLEASE) keep the titles on screen longer. Three minutes in and I’ve stopped and rewound at least four times so far to be able to figure out that Titan is 1000 miles wider than the Moon or read a person’s title. Please remember: as a viewer, we’ve never seen that info. Plus, I’m fascinated by all things NASA! Thanks!

I had watched Cassini and Huygens when it happened. It was great. As a kind of successor, for me, Dragonfly is the most interesting and fascinating science mission ever. Wish you all the best 👍🚀

[@Seventh7Art]

Possibly the best moon/planet for colonization in our solar system. No need for air pressurization, nor artificial magnetic field. Mars is closer to us and has more gravity, but good luck with the lack of air pressure and magnetic field.

[@homomorphic]

This video makes it seem that the liquid hydrocarbon lakes are a relatively recent discovery, but I recall reading Imperial Earth by Arthur C Clark in the late 70s and the hydrocarbon lakes were a significant feature of that novel (as were Waymo cars).

[@a.randomjack6661]

Glad this was recommended to me! Titan's my 2nd favorite moon, I'm always happy to learn more. I originally fell in love with Titan years ago, when I read that some chemicals had been detected in its atmosphere that were organic in nature (not knowing what "tholins" were yet).

[@Erik-rp1hi]

I guess they know the wind speeds on Titan are not dangerous for the flying machine. The atmosphere is 1.5 as dense and less gravity can be an issue in strong winds. Maybe screw type anchors on the landing legs are needed?

[@sp00l]

I don't understand why we never went back. There's lakes there... I mean, I know its not liquid water but still.... send more probes!

[@techdefined9420]

I saw the Huygens landing live. I never understood why it took so damn long to launch a new mission to Titan. Dragonfly is taking also far to long. Titan is by far the most interesting planet in the solar system. Huygens found chemical compounds that have not been synthesized on Earth.

[@Silverboarding]

My big question to this scientist is why the rover will land on the moon's ecuator instead of the near to the north pole where we will see a picture of a liquid lake and perhaps rains

[@bengoodwin2141]

We've only been able to look closely in one place so far, and we haven't even checked underground yet, that being mars. Do you really expect us to be able to solve one of the universe's greatest mysteries in less than a century of looking?

16:50 what is it hovering?

[@kaenchuli_Nevla]

It's not hovering! It's 'orbiting', meaning it's falling and moving forward at about the same speed (depending on the 'eccentricity' of the orbit). Also, it's not an actual footage, it's an artist's rendition of the concept.

[@NunoPereira.]

Will Dragonfly also be equipped to find life in the liquid part of Titan?

[@RussTillling]

Not sure, but it’s a quadcopter so possibly. It could dip its toes in shallow parts of the methane lakes and sample the liquid. There’s a video on Europa where the rover has a probe on the end of a cable which is going to heat its way through miles of ice and then swim or crawl on the underside of the ice!

[@DougieJohnson-l5w]

[@JasonFoster-z9i]

[@markw5509]

Help me understand why they can’t make more than ONE Dragonfly Drone / Rover? Why not send 3? Have backups in case one doesn’t work! Billions spent and it’s all wasted if the one rover doesn’t make it or crashes.

[@markjgaletti57]

You’re probably correct cheaper to build two or three than just one, but The launch weight Cost$ Out weigh common sense

[@zounds010]

There are a few factors that limit how many you can send there. 1. Rocket payload: Launching Dragonfly to Saturn already requires a Falcon Heavy. it takes a lot of energy to move a payload from Earth to Saturn (you're moving away from the sun, against its gravitational field). So you could build 3 smaller aircraft instead of Dragonfly (150 kg each instead of 450 kg). That means the science instruments have to be either divided over the 3 craft, or you have to spend more money making them smaller so you can put a full set of instruments on each aircraft. 2. Power: Dragon is powered by a radioisotope thermoelectric generator. This costs on the order of $100 million on its own, and each aircraft needs one. So again either you split the RTG into 3, so you get 3 smaller ones that limit the available power to the aircraft, and reduce mission lifetime, or you have to buy 3 RTGs instead of one. Production of the Pu-238 needed for these RTGs is so limited that adding two RTGs would delay the mission by a decade.

​@@NASAWebbTelescopewe may be moving to titan to take up residence if Congress doesnt stop the racket with Zelensky , the stock market and forcing the electric vehichle thing to happen *yes its good underground , however world war 3 isnt an ethical way to get there . I would love to work for NASA myself , highest score in state of Alabama concepts of numbers Stanford Achievement Test for one year , I moved to Florida alone on a bus with nothing due to a carwreck caused by a drunk driver running 99.9mph crossing a double yellow into my lane hitting me head on , justice wasnt served so i figured "I better get out of here because no one can afford this a 2nd time" long story but i can do so many things with computers and robotics its rediculous , quality parts and financial aspect is where im stumped but I would also like to work with Darpa if it will stop making machines meant to kill . We need machines meant to build and run efficienctly (i have high scores on a video game named battle of the immortals Poseidon server from perfect world and many others for this reason ,see i can record what i do on computer then schedule the recordings to stack , its a primative way to "bot" but for unique quests ) Im always looking for something more the video game itself just gave enough ways for me to do what i concepted id like for the bots to be "real" though & i can build them with a small budget but want i cant do is do it all alone . So but back to the subject at hand JamesWebb telescope is the best machine mankind has built so far . BE careful colorizing anything because every beacon streaming from stars in infered light are full of actual planets & I can prove this as i alone have discovered planets no one has seen before me : something i did with imaging from one JamesWebb infered picture ; I'd like to help you to.

P.s. so you know i mean what i say "transmission is everything ,gear or frequency" & "budgeting watts per daily solar revolution or fuel source is key" & "overcompensation of any forthcoming obsticals is crucial" downtime is an enemy to any accomplished project. - lastly I did not go to college I took internet development and computer engineering on my own time in the 90s however Ethics and Physics would have been my majors . From the heart ~we are all God's people long live the human race *God made space for us to explore so who are we to say no?*

One last thing to show i was paying attention but using my own resources to know things : " on the date year 2017 september 6th~7th the Earth experienced 2000x normal but "higher" radiation levels : for example .4 is the highest normal predate and on those specific dates the radiation reached approximately 945.`~980.` levels & I later found that what i perceived was right : Nasa confirmed a CME- X 9~10 factor (I linked the 2+2 together so to speak)

Methane actually has no smell to it. Gas from humans and animals has bacteria in it which gives it that smell. Pure methane is odorless!!

[@davidcadieu9238]

Yeah man but since it has about the gravity of Earth's moon, but a thicker atmosphere than the earth, if you could put on enough insulation and an oxygen mask, you could strap wings to your arms and flap your way through the air over lakes of liquid methane. That's pretty awesome, any potential smells aside.
