Megafloods and ice streams create similar landform expressions - did either create Martian outflow channels?

Anna Grau Galofre's team is asking this question. #EPSCDPS2025

Noémie Carlot presented an absolutely stunning map of Eberswalde delta fan, Mars. Look at all those lobes showing channel migration!

The river sediments were more resistant to erosion than the surrounding layers, creating intricate inverted channels. #EPSCDPS2025 #Mars

A greyscale delta on Mars. Colours are used to highlight inverted channels and delta lobes by relative age, blue being the oldest, pink the youngest.

A very succinct summary of Christian's talk today at #EPSCDPS2025 on our work studying the effects of perchlorates on meteoritic organics 👇

The presence of perchlorate alters organic compounds, but does not erase them - laboratory experiments on C12 acids

Friendly reminder that we've landed a spacecraft on Titan!

This photo was taken by the Huygens lander (Image: ESA/NASA).

Dragonfly Science Goals paraphrased fr Barnes et al. 2021:

How far has probiotic chemistry progressed on Titan?
What role do the deserts play in the methane cycle?
What are the transport mechanisms?
Where and how has liquid H2O been in contact with organics?

IS THERE LIFE ON TITAN?

NASA reviews are conducted using Dual Anonymous Peer Review, meaning you don't need to depend on name-recognition when submitting grant proposals.

You may need to be at a US-based institution, though.

Questioner: Have you gone back?
Speaker: We'd love to, but it's very challenging to get there.
Questioner: I've been there.

OK has every scientist even remotely related to astrobiology or paleoclimate been to Axel Heiberg Island??

Elise Harrington @elusieum.bsky.social · Sep 9

~*Axel Heiberg Island mentioned*~ in the Astrobiology session. #EPSCDPS2025

I was there with Mark Fox-Powell, just outside this image.

All that white stuff? Not snow! It's salts!

I'm sadly not there in person this year. I missed the abstract deadline and couldn't justify the trip.

Keep your eye out for new QGIS plugins for Hayabusa data, being developed by Mayumi Ichikawa and team at NTT DATA Corporation, in partnership with JAXA. #EPSCDPS2025

Does Callisto have an undifferentiated ice shell? If so, it might behave like salt tectonics(!) on Earth, or ice tectonics on Ceres. #EPSCDPS2025

There is a salt-rich layer at the base of Europa's ice crust, concentrating in fractures at the ice-ocean interface. #EPSCDPS2025

Check out Dr. Byrne's creative poster at #EPSCDPS2025!

Could Venus have been Earth-Like? As asked in ye old medieval manuscripts...

Paul Byrne @theplanetaryguy.bsky.social · Sep 8

My poster for #epscdps2025 is up!

Come stop by board F43 at tonight's poster session and learn why Venus could have been Earth-like only a few hundred million years ago...
