🚨 New short article! 🚨 We determined that underground methane, if present at Jezero crater, could be collected by Perseverance drilled cores at certain times/seasons. However, sample tubes would need to be capped faster than is correctly done to preserve pore gases. #Mars bit.ly/4nnLZv3

Does anyone have experience publishing in Icarus "Notes"? The format seems appropriate for what I'm thinking, but I've just never published that type of article before. #PlanetarySci #Mars #Publishing

🚨 New Year, New Article! 🚨 Gas diffusion-adsorption in zeolitic rocks behaves counter-intuitively when partially saturated. This has implications for radionuclide transport monitoring, and possibly even methane transport on Mars. doi.org/10.1016/j.je...

Best surprise on the 1am drive home from airport after #AGU24 was a prime viewing of the Gemini meteor shower!

My first time as a session chair at #AGU24 was a great success! Turns out a lot of people care about subsurface processes on Mars!

It's that very special time of year... #AGU24! For all Martians interested in Mars, sample return, subsurface processes, and exploration missions don't miss our oral and poster sessions tomorrow! The New Mars Underground: Fluids, Volatiles, and the Future of Mars Exploration bit.ly/3VvARzI
