AND, they are hiring (1 PhD, 1-2 Post-docs) for next year. 👀 #EPSCDPS2025

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

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

There are ore-grade nickel deposits in Neretva Vallis, near Jezero crater, Mars. #EPSCDPS2025

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.

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

#Relatable

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

3 things ahout Apophis we have to communicate as science community:
1) Apophis will safely pass the Earth
2) Apophis will safely pass the Earth
3) Apophis will safely pass the Earth

Image from the Huygenss lander. It is a hazy, orange/beige tinted landscape and horizon with rounded rocks in the foreground and background.

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.

#EPSCDPS2025

TIL: ESA funding costs the average European €14 per year.

"If you are fun to work with, you are wanted in every field."

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??

~*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...

Oh heck, Paul! I love it. You are always such a creative presenter.

I lived in Oslo for two years and never saw one. To be fair, I like sleeping at night when they tend to happen.

Europa and Ganymede, moons of Jupiter, have auroras! #EPSCDPS2025

Painted Desert, USA "looks just like Mawrth Vallis!" (Mars) - They both have thick beds of clays. #EPSCDPS2025

"Mysterious red blobs" in CaSSIS IRB (false-colour) images are likely impact-shocked anorthosite or other plagioclase-rich rock. #EPSCDPS2025

I didn't know him very well, but I am shook by this news...

I worked with Riccardo while I was at ESA. He was a fantastic scientist.

Titan is the largest moon of Saturn. It's the only other place in the solar system where we know there is liquid stable on the surface. Except instead of water, it's liquid hydrocarbons! #EPSCDPS2025

Today I learned that Titan has "ephemeral islands" i.e. islands or something floating that wasn't there in one (satellite radar) image, then appeared in a subsequent image. That's really cool. #EPSCDPS2025

The ESA-led EnVision mission (Venus satellite) is at risk if NASA withdraws funding for the VenSAR instrument. #EPSC-DPS
