Next #SETILive: The Hidden Ocean of Ariel
TODAY, 23 October, 11 am PDT / 2 pm EDT

Uranus’s moon Ariel shows fractures that may record the rise and fall of a 100-mile-deep subsurface ocean.

This week on SETI Live, host Beth Johnson talks with Caleb Strom (UND) and Alex Pathoff (PSI) about what the data reveal.

Weird oxygen production from metal nodules at the bottom of the ocean.

Link to summary article: https://www.nature.com/articles/d41586-024-02393-7#:~:text=The%20phenomenon%20was%20discovered%20in,published%20in%20Nature%20Geoscience1.

The authors found oxygen getting produced at the bottom of the ocean. They thought it was from instrument or experimental hiccups...but no, it's real.

So what's going on? And what are the implications for #astrobiology in the deep oceans of the #OceanWorlds ?

It looks like asteroid Bennu might be a remnant of an, "ancient, small, primitive ocean world!"

One of the big questions about the histories of #Pluto and #Triton is if they once had and potentially could now have internal liquid water oceans. The discovery of such #oceanworlds in our solar system have opened up a new field of #astrobiology.

For #OceanWorlds deep oceanic moleculrs, would we expect same chiral throw? If they are just water extracted meteorite material, maybe same.

To try to understand all this, it's key to understand the exact processes and inventories of molecules from primordial bodies: asteroids, comets, etc.

And this is why getting samples like OSIRIS-REX just delivered is so useful. It will be exciting to see what they discover, and cross-compare with Hayabusa analysis. Same, or different?

Exciting!

As part of our Network for #OceanWorlds retreat, we had a lab day where we collected samples off the dock and used the laboratory facilities of the Wrigley Marine Science center.

(Stay tuned, in this thread there will be an important implication for #astrobiology)

Thread on marine lab day.

Here we are lowering a plankton collection net into the water near the dock.

The Network for Ocean Worlds has an excellent YouTube channel with presentations from their lecture series.

(Full disclosure: I was one of the presenters on life in Deep Ice and was also a member the next year of the selection committee.)

I'll be part of the Network for Ocean Worlds retreat next week on Catalina Island. (Hashtag up #NOW_Retreat) I'll be running the problem solving/team building exercise. (And boy, do we have a doozy of an exercise lined up.)

It's a limited attendance workshop, but I'll try to post what tidbits I can.

And an invited guest, T(D? S?) Hilary will make a surprise appearance.

Info on the Network for Ocean Worlds, and how you can join in, is here: https://oceanworlds.space/

Do you want to see some neat images of Europa's surface?

Of course you do.

(Short thread on #OceanWorlds and #Europa)

Here is a neat image taken by the Galileo spacecraft of Europa's surface near 0, 228 W.

You can see ridges all over the landscape. There is a bulge is about 21 km across. The center is kinda-sorta collapsed, and dark stuff has oozed out or filled in the dark patch lower part of the image. the ridges at center of dome got rotated maybe.

But let's zoom in closer....

Scientific American short article on the six moons in our Solar System where we are most likely to find alien life.
#astrobiology

Quick article, cool-o comparison graphics of those places, and short quotes from Chris German (WHOI), Steve Vance (JPL), Alison Murray (DRI), and myself (JPL).

And yes, those moons are all #OceanWorlds.

Cryobot workshop!

First, a big Thank You to everyone who participated in that quick Mastodon poll last evening. That was extremely useful feedback.

This was a small workshop f about 30-40 people. Mostly engineers/technologists. I was one of the few science types.

Big focus on any deep drill mission onto the #OceanWorlds will focus on #Astrobiology.

So where should we go?

Each world has pros and cons (technical challengs)

Lets give a quick run through:

Turns out a compressed gas cart is really handy for moving ice cores.

Kicked out of a downstairs lab freezer, I'm using the freight elevator in the Science building to move to another lab freezer at Jet Propulsion Laboratory.

One of these is a section of firn ice from GISP2.

What am I gonna do with these?
Wait and see......

Here is a 30-minute detailed presentation/short course on the astrobiology of icy microhabitats like we might find when we explore the Ocean Worlds (Europa, Enceladus, Titan, etc.)

This was part of a Keck Institute of Space Studies (KISS) workshop where we gathered some researchers to try to figure out the technical challenges of targeting microhabitats during planetary exploration.

Our @EuropaClipper mission, now in development, will study this world in more detail, telling us if Europa has conditions suitable for life. #OceanWorlds https://t.co/v6ftgYXJC2 https://twitter.com/NASASolarSystem/status/1296556367633952771

If we’re talking about #OceanWorlds, we HAVE to talk about Europa. Jupiter’s moon has a global salty ocean beneath an icy crust. We believe the ocean contains about twice as much water as all of Earth’s oceans. Happy #OceanWorlds Week! https://t.co/Wg3mdx1fW4 https://twitter.com/NASASolarSystem/status/1296461419408494592
