h/t to @PaulHammond51 & Mars Guy for referring to the recent "10th International Conference on Mars" in the Cheyava Falls video. Only news or pointer I've seen to it.

The summary papers & posters are a treasure trove of upcoming research or incremental studies since LPSC

Tenth International Conference on Mars - July 22–25, 2024

The Tenth International Conference on Mars is a large, 500–600-person gathering of Mars scientists from a range of disciplines, institutions, and countries.

Using #MarsIngenuityHelicopter as a weather vane 😀 Preliminary analysis of telemetry to estimate wind speed & direction. Surprisingly strong winds detected!

Iteration/compilation of conclusions from earlier papers from this team.

Mangold et al: "Constraints on Jezero Paleolake History from Its Fluvial Input"

"A high variability in fluvial deposits is observed on Jezero delta front and top, which reflect variable fluvial regimes associated to Jezero lake level fluctuations in a closed basin."

A new iteration of analysis of Margin Unit boulders, this time with MastCam (compare to this earlier one with SuperCam https://mastodon.social/@sharponlooker/111870338355722359 ). Boulders "confirmed" to be coming from floods and differ from Séítah.

Here are #crackedRocks Oli and Dusty a few meters west of #Perseverance and all of them just west of Belva Crater.

On the map, the green area is the field-of-view of MCZ at 34mm.

@65dBnoise we have to find a Stan for that Oli 😀

Will be interesting to see this method applied to the Mount Washburn boulders and compare.

65dBnoise Jul 31, 2024

@sharponlooker
Would it apply to at least some of the other #crackedRocks we've seen around?

(didn't read the paper)

V Martín Jul 31, 2024

@65dBnoise it's a coarse categorization method but "simple to apply" (reminds of Tau's principal component analysis processing at UNMSF), more helpful with boulder field views. Nice with an in-situ additional datapoint to confirm those letter-labeled flows identified from orbit.

I suspect Mount Washburn and other such boulder-rich areas in Neretva will show more diversity. The #JezeroBrightRocks will require more sophisticated methods to identify their provenance.

@sharponlooker
You may add this one to those then:

@65dBnoise let's add a #PDSAnalystNotebook to it 😉

65dBnoise Jul 31, 2024

@sharponlooker
I added it.

V Martín Jul 31, 2024

@65dBnoise btw, did u see the Ingenuity paper? https://mastodon.social/@sharponlooker/112874308915904998

65dBnoise Jul 31, 2024

@sharponlooker
I saw your exchange with @PaulHammond51 but had no time and brain bandwidth to read it and the paper carefully. Still short on both.

V Martín Jul 31, 2024

@65dBnoise the good thing with these conference papers is they're brief & concise 😉

65dBnoise Jul 31, 2024

@sharponlooker
Ha, ha! Exactly not what I wanted. I'd like to see raw data and grok for once what kinds of data were collected, at what rate. We still have no idea what those were (are?); all we can do is infer those from brief papers and from scant words from conferences and interviews.

V Martín Jul 31, 2024

@65dBnoise I'm surprised the full telemetry hasn't yet been released even for the earliest flights? That's quite the proprietary period...

65dBnoise Jul 31, 2024

@sharponlooker
I just read through the paper. Interesting, especially the flights to higher altitude; alas, there was no MEDA data for those. Apparently telemetry includes IMU/inclinometer data, but we still don't know the details.
