Europa Geology & What it Means for Life on Europa w/Dr. Erin Leonard | GEO GIRL

[@GEOGIRL]

Go check out part 2 all about the mission on @geosociety: kzbin.info/www/bejne/gmmofqKihNSej9Esi=oPvKEh3sZDOoZnvg ! 🎉🚀🛰

[@bkbland1626]

I'm stoked. I only wish we were ahead of where we are, space wise. Exploring new places is what we do, when we're not blowing each other up.

STAR TREK space exploration, with shield and weapons :3

And we spend that money and lose those opportunities on killer war toys so others may live in wealth and luxury.

I'm crossing my fingers that Clipper gets there safe. This mission has a chance to answer questions we've had since Voyager.

[@MrSiwat]

Great stuff Geogirl! Thanks so much for all the hard work making these excellent videos.

[@GEOGIRL]

Thanks so much! So glad you are enjoying them ;) Make sure to check out part 2!

[@mrvan5347]

Idem tito. I completely agree.

[@PepsiMagt]

Great interview dr Phillips

[@Superwelder0]

You have discussed the reach of Earth science and the difficulties of translating that into informational outreach to motivate would-be scientists into the field of Earth science. Increasingly though, I find myself thinking we should just start calling it 'planetary science'. Videos like this one in particular have me convinced we as a species will only grow more and more interested in 'foreign' geology. Missions to other bodies will only become more realistic and capable. One day, I hope I can tell kids we had 'Earth Science' as a class in grade school to illustrate how far we have come because from the future kid's perspective, it's just the study of how planets form/work so they just generalize it as 'planetary science'.

[@thelostone6981]

Just how cool is the Europa Clipper mission??? Ever since I read Arthur C Clarke’s 2010 and 2061, Europa has had an appeal for scientific study and I’m so excited to see what they learn. (Even if that means there’s no life there)

[@OnASeasideMission]

My favourite topic in 'Lunar and Planetary Geology', (intercollegiate study at UCL🇬🇧) which happened to be Q2 in the exam. 😃😃😃😃

[@Firebuck]

Great video -- I'm fascinated by Europa's surface. I've downloaded the map -- thanks for sharing! I think it'll be my wallpaper for a couple months while I absorb some of the details.

[@GEOGIRL]

Yes! Europa map wallpaper is such a great idea :D

[@patrickgriffiths889]

Great work. Not convinced that life is likely on Europa, but definitely worth understanding the geology of the Galilean moons.

[@GEOGIRL]

Absolutely! ;D

[@axelbrass5858]

You are very good at this!

[@GEOGIRL]

Thank you so much ! :D

[@iamsuzerain3987]

Fantastic video GeoGirl. Super excited about the things we'll discover with Europa Clipper as well as the JUICE mission. This was so informative and enjoyable to watch, great job❤👍

[@GEOGIRL]

Thank you so much! :D So glad you enjoyed it, make sure to check out the part 2 over on @geosociety !

[@colinmetzler]

I think this is my favorite video of yours that you have ever posted. So amazing and exciting!

[@rursus8354]

Very good interviewing, very good interviewee!

[@GEOGIRL]

Agreed! Dr. Leonard was incredible to talk to! I hardly had to edit at all because all her answers were so great and interesting :D

[@J.Battles]

On to part 2!

[@GEOGIRL]

Yay! Hope you enjoy, that one is so good! ;D

[@matsciguy-l9h]

Fantastic content, thank you!

Thanks so much! I am so glad you enjoyed it :D Make sure to check out part 2! ;)

[@shadeen3604]

great video Dr geo girl thank you

[@GEOGIRL]

Thanks so much, so glad you enjoyed it :D Make sure to check out part 2! The info about the mission is so exicting ;)

[@JKTCGMV13]

Hell yeah science lady I wanna hear all about Europa

[@nomadicstrength]

Fine! I'll go watch The Europa Report again.

[@trtlphnx]

Love The New, Sleek look: keep it up.

[@elgendystones]

You are so smart , keep going 🌹👏

[@ericneff9908]

Very excited for this mission and very impressed with your interview. Thank you!

[@digitalexpertagency]

You are so smart , keep going

[@nathanaeldownes2848]

Love your channel buddy, rooting for you. Great interview

[@GEOGIRL]

Thanks so much! Glad you enjoyed the video, make sure to check out part 2! ;D

[@Texan190]

Europa is cool. Would love to see us get more info and explore Enceladus around Saturn. Its similar to Europa with liquid water and obviously some subsurface heating going on with the geysers.

[@sirensynapse5603]

👽plenty of life out there

[@suemacias667]

Great interview! So interesting!

[@johnp9988]

That was super interesting thanks for sharing!!!🍻

[@mikefochtman7164]

So... with this tidal-friction heating of the interior, that energy must come from somewhere. Does this mean the orbit is decaying more rapidly than it otherwise would? Any thoughts about how much this shortens its lifetime?

[@chrysanthemum8233]

This is so exciting and I'm absurdly pleased that they're launching it within a few days of my birthday. Totally not in my honor but I'm going to pretend anyway, NASA is throwing another robot into the sky to take pictures of something I've been fascinated by for years.

[@GEOGIRL]

Yay! A birthday launch, how exciting :D Happy birthday!

[@meesalikeu]

oh this is rad - very interesting - i have the europa clipper launch noted to watch (this thursday oct 10) - thx doc geo 🎉

[@meesalikeu]

also, because europa’s surface cycles so much maybe we can spot a few space whale fossils sticking out. 🙀

[@GEOGIRL]

I think the launch was slightly delayed since I filmed this video, I think now it is the 12th, but I will check and make sure and then pin a comment to let you all know! ;)

[@violentinstincts]

by "WE" we mean NASA, and by "just a few days" we mean 6 years.

[@Musabre]

I find B=being able to temper your impatience, and have a healthy respect for astrological distances is somewhat neccessary not to go completely mad as an astrophysics fan 😆. It's gonna be worse than waiting for Dune Messiah, or GTA6 lol.

[@toweypat]

Is it possible Europa was warmer at some point in its past?

[@GEOGIRL]

Absolutely! Very little is known about its geologic history since its formation (even the timing of its formation is still debated), so yes, especially if it has undergone changes to its orbit in the past (like Earth and other planets do). But by investigating Europa's geology (and that of the other major moons of Jupiter) we will start to unravel that history of their formation and evolution over time :)

[@LiamRedmill]

Going off your questions and the awnser's,(10xthe gravity of Enceladus)has this gravity been assessed through relative mass/weight and distance or from spectroscopy scans from earth and space.does the moon have an molten iron or silicon core that is churning like earth or is it possible it's high gravity is relative to a mini sun or black hole at the centre of this and all bodie's in the solar system,and not magnetic churning of metal's,and how is the current theorie's and alternative's proved or provable.great production,so happy that you have become such a successful science communicator.sorry for the difficult question's,wish you all the best in your work,thankyou

[@the_eternal_student]

How would you even find out about that subsurface stuff?

[@charlesjmouse]

Very nice! I'm curious - at the time of this comment this video has three down-votes - not bad for KZbin. As it's utterly beyond me, would the three people who down-voted this video like to explain why?

[@Musabre]

Boy i really need some better channels for getting the heads-up on the latest space missions. I feel like i only ever learn that some awesome mission exists when it's already happened xD

[@anothersquid]

Doesn't the Earth's surface rotate somewhat independently of the core due to the layer of liquid iron? Does that cause any weirdness on Earth?

[@mikefochtman7164]

Well, we do have a magnetic field from the rotating core. This shields us from 'solar wind' to a great extent. We've found this is not universal in all the planets.

[@anothersquid]

@@mikefochtman7164 I knew that, but I'd often wondered how coupled the mantle and crust is to the core given the ocean of liquid iron. When it came up about the ice floating on the water ocean, it struck me that such a situation would be similar but with possibly increased effects since water is (I think) less viscous than liquid iron. My background is physics, but I only studied the minimum geology (hard to avoid - university on west coast, so there's lots of geology :) )

[@barryfennell9723]

Even though Europa is far from the Living Goldy Locks Zone of the Sun, Jupiter creates geologic activity with its crushing weight that could potentially have life on Europa similar to Earth's deep oceanic life. If Europa was vacant then trying to seed life there especially as the sun expands.

[@harrygoldhagen2732]

Great interview! Wouldn't it be cool if those colored bands were caused by bacteria, they way they are at some of the hot springs in Yellowstone?!!

[@LiamRedmill]

With the long held prospect of life or dark oxygen,,,what are the precaution's taken to protect this pristine world from microbe's/virus's/diatoms from our world?

[@GEOGIRL]

Well Europa Clipper is only going to do a flyby, so it is not going to land on or contaminate the surface. But that is a great and very important question you have asked! I think it is something that future missions to these moons, especially landers, will heavily consider. (Thankfully, though, hardly any Earth life would be able to withstand the trip to the outer solar system- it is much longer and more treacherous than just going to Mars, for example). ;)

[@LiamRedmill]

@@GEOGIRL thankyou so much for your prompt response,I feel silly now,but also have more complex questions,,,like will spectroscopy play a part in the mission,and has spectroscopy ascertained the moon's makeup,,,ie churning iron core magnetosphere/gravity(10xthat of Enceladus),,,and can spectroscopy be done from earth or do you get a better elemental/mineralogically picture with instruments the closer you are(or the more the moon is "not aligned with Jupiter/the sun).maybe these are questions you could research/ask the expert's in the future ,thankyou so much

[@RommelSanico]

🤗🙏♥️🌷😃

[@PatelShirishbhai-y5x]

I love you bae

[@StevieAF]

They should definitely look under the ice, but I doubt they'll find anything. Life began in ponds.😉

[@thelostone6981]

Or deep sea volcano vents or petri dishes. We may never learn of how life started on earth 4 billion years ago, but taking a peek on Europa may add to our understanding abiogenesis and I’m excited to see what the scientific community finds there.

[@LiamRedmill]

And hydrothermal vent's and possibly around dark oxygen batteries
