PRESS RELEASE: https://www.seti.org/press-release/giant-volcano-discovered-mars
Giant Volcano Discovered on Mars

A deeply eroded giant volcano, active from ancient through recent times and with possible remnants of glacier ice near its base, had been hiding near Mars’ equator in plain sight. Its discovery points to an exciting new place to search for life, and a potential destination for future robotic and human exploration.

MartinHajovsky,

@setiinstitute There will be a talk about these Mars volcano findings in eastern Noctis Labyrinthus this afternoon given by Pascal Lee at 4:50 p.m. at . Here is Lee and Sourabh Shubham's abstract: https://www.hou.usra.edu/meetings/lpsc2024/pdf/2745.pdf

I'm excited to announce that my PyHAT software is once again publicly available!

https://code.usgs.gov/astrogeology/pyhat

If you work with spectra or multivariate regression and don't want to reinvent the wheel, check it out. If it doesn't do what you need it to do, let me know and we can add capabilities to make it work for you!

LPSC is happening this week. If you aren't in the planetary science community, it's the largest conference of the year dedicated to planetary science research.

It's now been 5 years since I last attended (2019), skipped peak COVID years obviously, but wish I had attended last year during my postdoc.

Regardless, I'll be following along as best as I can vicariously. I know several friends and colleagues giving talks this week and wish them all the best!

I am not attending , but I am reading through abstracts.

Dong et al. 2024, "Detection of airbursts on Titan with Dragonfly" - https://www.hou.usra.edu/meetings/lpsc2024/pdf/1955.pdf

Knowing the frequency of few-meter impactors at Saturn would be very interesting.

Taylor et al. 2024 discussing "dark comets": Near-Earth asteroids with no observed outgassing but measurable non-gravitational acceleration - https://www.hou.usra.edu/meetings/lpsc2024/pdf/1929.pdf

Consistent with a combination of episodically putting out just a bit of water vapor and spinning up to breakup.

Addendum:

"dark comets" are near-Earth asteroids with no observed outgassing but measurable non-gravitational acceleration that cannot be explained by radiation pressure.

Lunar and Planetary Science Conference abstract submitted! Number 1692.

"Dune Mixing in the Huygens and Dragonfly Landing Sites Region, Titan."

And, of course, the abstract haiku:

Like Earth like Titan,
At beach or in dune terrains,
Sand gets everywhere.

TerraSabaea, to Kurzgesagt

Started work on my abstract for today! I've been slowly mosaicking frames from the MARDI drive videos collected while exploring . Once they're georeferenced, I hope they'll be of major use to scientists working to piece together the environmental transitions taking place on Mars when the Marker Band was deposited! Here's a roughly 4 m x 1 m segment of the drive performed on Sol 3648 (November 10, 2022).
