- Titan is the largest Moon of Saturn; this natural satellite is of great interest to scientists since it contains chemical compounds that living beings could produce, that is, by extraterrestrials in the form of microbes.
But despite our great scientific interest in this planet, only four space exploration probes have managed to reach this distant world, and only one has managed to land on its surface.
Why haven't we sent more missions to explore Titan? Is it tough to go to Titan?
Titan, the giant of Saturn
The largest satellite of Saturn was discovered on March 25, 1655, by astronomer Christiaan Huygens. At that time, Huygens had no way of determining the size of this natural satellite, but due to its brightness, he estimated that it could be as large as the Moon.
Years later, with more advanced telescopes, the diameter of Titan could be precisely measured, revealing that this satellite was bigger than the Moon and even more bigger than Mercury.
However, until 1979, the only thing that was known about this gigantic satellite was that it was more significant than Mercury and had an intense brightness, but it was not known why.
Pioneer 11 exploration probe flew over Titan and sent the first images of this natural satellite.
Later, the Voyager 1 and Voyager 2 probes would fly by Saturn in 1980 and 1981, respectively. When the Pioner11, Voyager 1, and Voyager 2 spacecraft flew near Titan in the 1980s, they barely captured a few images of this distant world.
The main objective of these exploration probes was to capture data from the gas giant planets. Still, NASA engineers concluded that it would be better to take advantage of the fact that the spacecrafts was already close to those moons to bring them closer and take some images of those distant worlds in more detail.
That act of curiosity to see what was in that distant world would end up being the beginning of something much bigger.
The first spacecraft to fly over Titan was Pioneer 11, taking the first photographs of the satellite, which allowed us to observe a dense, gaseous atmosphere. Thanks to this, the Voyager 1 mission controllers decided that the probe should make a closer approach to this Moon, so it was diverted from its initial trajectory to make a closer flyby of Titan at less than 6,500 km.
Unfortunately, Voyager 1 had no instrument to penetrate Titan's fog, so data could only be obtained from its upper atmosphere.
The mission that revealed the secrets of Titan
The Cassini-Huygens mission was a joint space project of NASA, the European Space Agency (ESA), and the Italian Space Agency (ASI) that aimed to explore the Saturnian system, particularly the planet Saturn and its fascinating moons. This mission represented a milestone in space exploration, providing invaluable information about the composition, atmosphere, and hidden secrets of this distant corner of the solar system.
Why should we return to Titan?
Titan is a very hostile world for life as we know it, especially for humans. Temperatures on Titan are frigid, having an average temperature of -290 degrees Fahrenheit ( -180 degrees Celsius ).
Dragon Mission fly
Although, at present, there is no proposal for a human-crewed mission whose main objective is to study the Titan satellite, there is an uncrewed mission that has that objective.
This is the Dragon space mission Fly. This proposed NASA mission is designed to explore Saturn's enigmatic moon, Titan, fully.

WHAT-IS-GRAVITY/DEQUANTIFYING-GRAVITY-EFFECT/GRAVITY-EFFECT/GRAVITY-SHADOW
Is gravity just the accumulation of physical properties? Gravity is more so an 'effect', than it is an actual thing. So, does this make gravity[effect] just the 'accumulation' of 'physical properties'? And then it entropies (buildup of gravitational effect) as time goes on. Gravity is the "shadow" of physical properties!!!
...................
Gravity has more in common with a shadow, then it does with anything else.
I shouldn't have said "dequantifying"... I think in the quantum realm, the equivalent of a shadow... Is 'gravity'.
Great info, thanks. I find it humorous how the voyager probes are always shown with their parabolic dish pointing in the direction they are going and not at earth where they are coming from.😅
I think Titan is to hostile for a colony, but it´s likely that we will send mining robots there in the future.
Titan is very promising. Everywhere outside of Earth is hostile. If there's nothing Earth-like around you look for size, density, atmosphere, magnetosphere etc. If you're going to be in enclosed habitats regardless of where you go the selling points become the comparable gravity, radiation protection and minerals.
Not to mention not needing a pressurized suit due to comparable atmospheric pressure...I'm surprised at the OPs comment.
Mate it’s cold there
@@nik_hithu We have settlements and research outposts in Antarctica. It's around -70c there. It's not much more of a stretch to handle titans temps.we can do it
@@DaDaDo661I think Titan is just a little bit colder than that (-178c average) but I still agree; I have no doubt we’ll have a colony/base of operations there in two/three centuries.
Yep, compared to the Moon and Mars Titan is much more benign. There are only 2 cons in regards to Titan. Distance and Temperature. But both of those can be overcome. Big pros are the fact the moon has a substantial atmosphere. Which is only 1.4 times denser than Earth, so if we would place habitable domes their, they are not required to be pressurized. Same goes for spacesuits. No need to pressurize them. Another big plus is the atmosphere providing protection against deadly solar and cosmic radiation. On the Moon and on Mars there is no such protection. And the dense atmosphere in combination with the low gravity makes flights very economic and even a human could fly on it's own power. Imagine that, just wearing a spacesuit that insulated you 100%, but isn't pressurized, you put some flaps on your arms and you can fly away. What a delight. And then the chemicals on Titan that makes it memorizing. Imagine how it even looks; a complete 'sea' of liquid methane? Would it be transparent? Would it be viscous? Are there waves? Can you even swim in it (assuming your suit is really 100% insulated). How would a shoreline of a methane sea look like? So fascinating, forget the Moon and Mars, both of those are dead, dusty and boring.
I was watching another video about the liquid lakes of methane on titan. One of the things they talked about was whether or not you could swim in it (disregarding temperature). The answer was no. It is liquid but far less dense than water. You couldn't generate enough force with your flailing arms and legs to even stay afloat. You'd sink like a rock in water.
I love the 2023 mentality that we go to titan for hydrocarbons.
By the time we have the capacity to get there, we will be very much beyond our hydrocarbon lifestyles
Great video and information !
We can barely survive on our own poles on earth....
The change of velocity required to get from earth orbit to Saturn is about the same as the change in velocity required to get from Earth's surface to low earth orbit.
this is excellent food for the mind in many subjects...super !
True, too tough to travel to Titan, though testing those theories takes time...
Can you imagine if titan were our moon? It would have been a mini earth.
If Titan were our moon it would have lost its atmosphere, and almost all the water it has, what would be left would be a stony core - probably smaller but otherwise similar to . . . our moon.
@@andrewworth7574 not necessarily there have been simulation videos on this that shows titan would have turned into an earth like planet.
@@SteelRhinoXpress ah, no, Titan at 1 AU from the sun would be too warm to retain volatiles due to its low escape velocity.
@@andrewworth7574 then tell that to the scientific simulations that suggests otherwise.
@SteelRhinoXpress I'm not interested in such fiction.
The physics is straight forward, volatile molecules like H2O, CH4, N2 cannot be retained by bodies with low escape velocities like that of the moon and Titan as close to the Sun as Earth is, even Earth has too low an escape velocity to retain molecular H2 and He over geological time frames.
I don't believe anyone living today will never see humans on Titan. There is just no compelling reason to spend that kind of money and human effort.
if there is not a terrible war happening soon, yes I think we shall be able to go to Titan one day
United States needs to keep the Weapon industry from going bankrupt....so....expect more wars provoked by them
"Space is big, I mean really big."
After the Moon, Titan should be the destination of choice for human expansion in space.
I'm so sad for the educational literacy of space science for generations that will come.
When I was a teenager I learned in highschool that our galaxy is one of trillions adrift in an cosmic aquarium. That this cosmic aquarium with our universe itself is one incarnation of a Universe adrift in a celestial ocean with trillions upon trillions of Universe incarnations. That our universe is created from invisible matter and energy. That the possibility of traveling from one planet to another would one day become possible but to travel from one solar system to another was virtually impossible. Science fiction is wonderful for the growth and imagination of Young minds. But reality based CZcams channel feeds such as this are paramount in understanding that the knowledge of space travel and space science should be taught. But we should provide our children with ways to explore the oceans and seek to improve alternative energy sources so that humanity may live and survive another 100 years
It would make a great gas station, if we still used that form of energy in the future.
Well according to Thanos, the planet doesn't have finite resources
😂😂😂😂
I don't know. Maybe because it's insanely far away???
Send the tardigrades!
If Titan is As big or Bigger than Mercury, then wouldn't that designate Titan more as a Planet than a moon?
Which in turn would mean Titan could be the so-called Illusive Nighth Plaent?
But it orbits Saturn
@@igglye6805 who says that cant happen.
@@TheBlindDyslexic what
I consider Titan as a planet as well. And I consider Mercury more like a moon
By definition planets orbit the sun, moons orbit planets.
Well, for one thing, there are no flights that go to Titan. Nor any ships. No roads lead to Titan.
The only way to get there is by walking for a really really really long time. Also, you need to be wearing very very thick clothes because I heard it gets very cold over there.
Now that I think about it, I am good sitting on my warm couch watching YT and making silly comments. You can try going to Titan, if you want. 😏
I thought the only thing that creates Methane is organic lifeforms ...
bcoz we not yet even mars?
I'd love to venture into the outer solar system in order to get me some delicious, energy-rich hydrocarbons, but does anyone know where I can find the oxygen to burn them with? I'm kinda afraid to use any more of what I've got here; I may need it for other stuff, like breathing.
I do believe that it's possible.
he said once titan planet. titan is a moon not a planet
so there's more life in the universe ahem in the solar system
That's what she said
Pls can you make a video on why space exploration unions can't use non cost efficient methods to tackle space exploration problems with Thier various almost unlimited resources as a union?? Please
What "space exploration unions" are there?
No one has unlimited resources.
It takes more than resources to explore space. It also takes time and scientific knowledge.
Titan was like most planets. Too many mouths, not enough to go around. And when we faced extinction, I offered a solution.
Because it's very far... You're welcome
To make it short and simple, we will never leave earth
Moon landing(s) denier, eh!
i think we will but it will be a long and slow progress taking hundreds of years
And nobody thought man would ever float across the Pacific to Hawaii. Yet that's what happened. Be careful with words like ever & never.
Probably never go much further than the solar system
Mars and the Moon
Did you not see Avatar?
It's not necessary to reach Titan now. We barely made progress on Mars. A 7-year trip to Titan is long. It's going to be quite some time before we can send people there as the time frame is too long. If they arrive there and leave immediately, you're talking about close to 15 years. Ain't nobody got time for that! 😅
I wonder if Dragon Fly is a good use of limited resources?
Answer: LONG distance!!!!!!!!!!!!!
00:20 it's not a planet.
Yes, and...??
7 ads in a 12 min video is RIDICULOUS you’re not that strapped for money. Do better please
They have to go back, otherwise they’ll never find the drunk fish.
Viagra platter at Hooters?
Really dumb question - it's hard because it's so far away!
