Back in the day, Carl Sagan used a planetary probe (can't remember which one) to try to "discover" life on earth during a gravity assist flyby. Just to see if it would be possible with the instruments of the spacecraft only. I remember the cover of Nature, "Is There Life on Earth?" It wasn't obvious or easy.
28:22 Yes, but not because of the solvent. Because the biochemistry on earth is based on proteins, which are amphilic, they have just as many polar as apolar patches on their surface. The reason is that they have to interact with other proteins too in the proper orientation, facilitated by the hydrophobic patches. They would fold differently in liquid methane, but they would still be as solvable as in water.
That's the first time I've heard a claim that we've found an abiotic explanation of the Viking 1976 results. I'm still perplexed as to why the multiple landers since then haven't tried to repeat or expand that experiment.
Thank you Dr. Cable. Great presentation. I learned a thing or three. What an amazing time to exist. Hope we find evidence of life before my expiration date.
If that is Enceladus behind her on the thumb nail, isn't it upside down? My dream is to tour around the orbit of Enceladus. It's the most beautiful thing I have ever seen in space.
@@JK-dv3qe I know what you mean, but there is a standard point of view of the solar system based on earth's north pole, so using that as a guide, Enceladus, if that is what it is pictured, appears to be upside down. Or all the promo pictures of the moon were shown upside down originally.
A lot of interesting things was told. Thank you. If there, on Titan, are lake and rivers exist why we didn't have for now an boat or more submarine with sensors, spectrum analysis of all kind ( gas, liquid, minerals, mass). If I understand, at the Titan dark a lot, it's opportunity for using lasers to connect our science boat with orbital device on a high speed. In that case all materials & liquids under the egg shell may be analysed on the surface, as far all material goes through vulcanos and other holes. How to dig down the ice at Titan ? It's the question.
Many Titan missions that include balloons, submarine, buoy, airplanes have been proposed! But NASA hasn't funded them until now with Dragonfly mission to fly a quadcopter drone in the dunes of Titans equator! It has a seismometer to detect earthquakes and potential sloshing of the subsurface ocean. I would love to see an explorer near the seas but Dragonfly is great enough
Were not from this planet, the gravity is to high, I get chair sores, and Elon Musk says the gravity is barely right so that rockets 🚀 can leave this world 🌎, if you had a choice then maybe chickens can fly
We need more like her!
I just Love her enthusiasm..... She got me all excited of the not just how but when.
Great talk by a great lecturer, as usual!
18:25 to 18:35 ''I don't know what it is in fahrenheit I'm a scientist'' 😂

A highly informative and exciting look at the possibilities of life within our solar system.
This was the best among the ones i have watched in Von karman lecture series 😍
What a lovely presentation. Absolutely absorbing... 👏👏
Soo passionate and enthusiastic. Luv it.

🎯Perfect Talk, I love perfect Talk.
Bravo!😷👍
Marc-André Brunet You said that perfectly! 👏👏👏😊😉
I love it , Thanks for the accuracy in describing the conditions around the moons, and the experiences of biology

We need to explore ways to clean our own oceans of plastics, a truly worthwhile endeavor, before OUR world dies.
Worthy of a Nobel, to be sure
Really enjoyed this. Thank you.

Great question!
My guess is money. These things cost almost $1B to make, and they make sacrifices as to which instruments go on landers.

Thanks for subtitles! 🙏 Btw amazing talk
Very important research, studying the unknown unknowns. Same with clipper, don't want to have any accidents there.
FYI: The English subtitles are very, very out of sync. The auto-generated one is working fine, though.
36:50 is the most useful bit of this hour...
43:50
18:55 was interesting aswell. The talk should be titled: NASA and hair.
Great talk. Hurry up with the results already!!! ;-)
What strange and alien creatures live in those dark watery depths on Europa!...🥺....🐉🐡🦈
Jupiter's satellite Europa Ocean worlds agree wtih. It makes more sense to look for life in icy places like Europa, Enceladus instead of Mars.
These mini planets have water and heat sources. There's no way there isn't life. I can't wait to see what it looks like.
The entire lecture is based on Data.Eventually that data is enough to create life on other worlds.

There's NO WAY that there isn't life on Enceladus and Europa...no way!
What about the stuff we don't know we don't know?
They must have alot of compassion as they could have destroyed us by now.
We already know that ET life exists, it’s here on Earth. Unfortunately it’s the most classified subject in the US government.
Is it that orange guy???
