Starting Day 2 in the DART session. At #LPSC2022, there was so much talk about how cool DART was going to be. At #LPSC2023, there were so many pretty pix/early results of DART giving Dimorphos the old 1-2. Now at #LPSC2024 it’s on to the serious detective work of what DART found.

Just want to say my #LPSC2023 presentation look came together *extremely* well, it's one of the first times I can say that I have been extremely happy with how I'm dressed for public engagement.

It was my pleasure to speak about MARDI sidewalk movies at #LPSC2023 this week. I think they're proving to be a valuable tool for stratigraphic documentation in Gale Crater, and with luck we'll be collecting more in the future.

Rivera-Valentín (@PlanetTreky): On Mercury we're likely looking at pure ice than can be modeled with possible ice+ silicate grains. At Moon, inferred values likely vary from scattering primarily from ice to backscatter from ice + silicate grains + porosity

This week the Lunar and Planetary Science Conference #LPSC2023 is happening near Houston. It's the reason the data release is timed for mid-March, giving #Curiosity team members free rein to talk about the most recent data possible. I searched the abstracts there for the Canaima drill target, and found this one that tells me the mission considers sols 3052 to 3572 to have been spent in the clay-sulfate transition region. (PDF at link) https://www.hou.usra.edu/meetings/lpsc2023/pdf/1662.pdf

Alyssa Rhoden at #LPSC2023: cryovolcanusm on Pluto's moon Charon.

Idea is that freezing ocean cracked Charon ice shell, and then caused cryovolcanic bloops.

So they modeled it up. (Recently published)

They added ammonia. Not sure if ammonia is there or not. But it affects temperature of freezing (makes it lower).

Makng Fractures is easy, but...making eruptions is hard. (10 km thick or thinner for a through fracture.)

Julie Castillo-Rogez at #LPSC2023:

Looking at evolution of Uranian moons. Clathrate hydrates of CO2 don't form because any CO2 goes into carbonates.

Miranda may not have a deep ocean... but maybe it is there? Worth a look!

General pattern:
Differentiation-->Hydrosphere Freezing-->Thermal metamorphism-->Resonance Melting->Freezing to Present time

Conclusion: Relict oceans. Unless tidal heating for Miranda.

Tara Tomlinson et al. Permeability and porosity of ice. At #LPSC2023.

Mushy zones in ice. How to nutrients and salts get formed and connected during ice Freetown?

(Y'all know I'm all into this for #astrobiology. This sets #microhabitats scale in #DeepIce.)

Modeled, and compared with lab grown sea ice.

Henry Dawson presenting on tectonic activity potential of Europa or Enceladus seafloor at #LPSC2023.

(Points from me for mentioning getting trace metals for catalytic enzymes into potential biosphere for #astrobiology, just a passing mention, but got me all happy.)

Can tides fracture sea floor?

Calculation path: Pressure to porosity to cohesion (rock stronger under compression than tension).
...More math.

Answer: Tidal forces not enough.
More optios..see abstract: https://www.hou.usra.edu/meetings/lpsc2023/pdf/2822.pdf

Zhimeng Zhang: #LPSC2023 Juno spacecraft microwave observations of Jupiter satellites.

For Ganymede microwave brightness temperature correlates with optical. (Anticorrelated)

Microwave probes deep. So this tells you that something at depth is driving surface optical stuff.

(Ganymede's beauty is not just skin deep (my interpretation)
