@@SMGJohn I think he knew that, but also like, what's really the difference, we got moons around these gas giants bigger than Mercury, or Pluto and one of those two is still considered a planet. It's bigger than some planets, and it's got a thick atmosphere, the only difference is, that it's orbiting a gas giant instead of out on its own. It's still like full world with a weather and seasonal cycle and all the fun and interesting stuff.
One concern I have is that the “rotors” are the outer most horizontal surfaces. It seems a that some sort of wire frame, regardless of how light may prevent the rotors from accidental contact with something that could damage or destroy them.

They should send two, in case one fails. Waiting so many years just to witness a catastrophe would be stupid. They should have done the same with that Europa mission.
The thing NASA has in abundance is time. It would be silly to send two at once and have them both fail for similar reasons. If one fails they can learn from it. Less at stake with Voyager missions as they weren’t landing anywhere.
Awesome video as usual, just one small mistake: Huygens only landed on Titan in 2005. It was launched in 1997 yes but it only landed on the foggy moon at the end of the mission, and survived for about 54 minutes!

Would have been better to make the copter buoyant so it could float on Titans ocean. Add a line to do some 'fishing.' On Earth, the vast majority of life forms are in the ocean. Possible that may be the case on Titan also.
Good point. Even some sort of floating punt with an AI controlled sail and rudder landing on one of the oceans? Probes dropped into the methane seas could gather a huge amount of data. It could have a small drone attached to the top of it for aerial missions. I'm sure a mission like this is already being planned. What a great time to be alive!
An RTG should have an abundance of power and life. I would no be surprised that once it's main mission is complete that they send it to the methane lakes and then on to the pole.
Big Leap? We are still using the same chemical rockets that we used in the 1960! That's more than 60 years ago and you call this a bit leap. Come on!!!!!
Something that never fails to amaze and befuddle me is the sheer variety of environments found throughout the moons and planets of our solar system. You’d think, logically, that they’d all be pretty similar, as they all formed from the same materials, but they are far from it. I wonder what causes these crazy variations?

I hope they take into consideration the possibility that when it lands the skids might get frozen to the surface. I hope they provide some heating for the landing skids.
@@ReddwarfIV Martian atmosphere is denser than Triton's. You would not feel a difference between the vacuum and Triton's atmosphere. And, it's 1/70,000th the pressure of Earth. You forgot to put a zero at the end of the number.
Titan isn't going anywhere but, at my present age, I'll be dead before Dragonfly gets there - bummer - Titan is mega-intriguing. I would like to see photos of the river valleys where they empty into the methane seas, and I know that's for a future mission ... so speed things the hell up!
We should have included a drone submersible carried by the aerocopter as part of this mission. If there is life there, it is most likely in Titans seas. Huge missed opportunity. 😢
It explains in the clip that it is not operating anywhere near the methane seas. Those are up near it's north pole where they say it is very hard to land. Though I'm sure they are working on a mission to there where a treasure trove of data awaits.
Can't they just land south and fly towards the pole? Is this a range issue? Can it be part of an extended mission if it lasts years longer than expected, as many NASA missions do? Or is it still too far out of it's range?
I’ll be 90 years old when it lands. Been following space exploration and development since the late fifties. Seen it all. Now waited over 50 years for the next manned moon landing. I’m a patient guy. Hopefully when I reach 100 in 2040 we’ll be able to see asteroid miners drinking in “SpaceX City” saloons on their six-monthly breaks.
1:45 - Excellent video! I love Titan (from the far😊). This moon is the only body in the Solar System that has a "stable body of liquid" on it. I am not sure whether we can talk of a hydrolic cycle when we know that the water there is harder than granite.
There are some problems with the numbers: 13:05 Dragonfly will spend 3 Earth years or 764 Titan days... 13:22 Dragonfly will lift off once per Titan day which is 16 Earth days... If 1 Titan day is 16 Earth days, than 764 Titan days are 12224 Earth days which is more, than 33 Earth years, not just 3 so at least one of the numbers is totally wrong.
Thanks for this. Very interesting. But you sort of glossed over the communications link. Will that little flying rover be able to communicate back to Earth entirely by itself? You didn't mention an orbital vehicle.
I wish that they could send more than one of these helicopters over there at a time. I wish that they could deploy 20 of them to go in 20 different directions all at the same time.
Divert more material from around Saturn to build up Titans mass. Use it's wind to produce electricity. Float clear spheres with fins and dynamos, they tumble to produce more light there.
Well, he didn't exactly *_explain_* it at all. While the following also does not explain it exactly, it may cast more light on the subject. The melting point of methane is 91.15K - this temperature may be slightly different on Titan, due to somewhat higher atmospheric pressure. The surface temperature on Titan is fairly constant at about 94K, or about 3K or 4K higher than the melting temperature of methane. This means that, when there is methane precipitation, it may fall as snow or rain, but once on the surface, it will be liquid. HTH...
NASA needs to start sending massive swarms of drones for all the planets and moon and do so much more why do they only send one in one area I understand that technology is expensive but they need to start sending millions of swarms on every single planet and moon swarms.
This is amazing! Now I can totally understand the costs of a mission like this, but I can't help but feel as a redundancy for such a high risk mission, that a second dragonfly (separate but parallel mission) should be sent to another area of interest where a landing is possible. Much like the 2 Viking landers sent to Mars many decades ago. If this single lander fails it would be a shame to achieve nothing for all that cost. But of course cost from the very beginning is the issue.
Sending down a nuclear rotor drone where it rains gasoline. I’m mean, what could go wrong? I hope they pull this off. What fabulous images will flood our simple human minds.
