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

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.

Lots of activity around noon, and it appears to be LIBS pulsed. That could mean that the laser is quite noisy, but of course it is to be expected since mic and laser are located very close to each other.

@65dBnoise and it's "intentional". From the mic operations section, right above the graph:

"IC+LIBS (Microphone plus SuperCam LIBS) continuous mode, the microphone is turned on to record the LIBS-induced laser burst at 100 kHz. Given that the laser is shot at a frequency 3 Hz, a maximum of 120 shots occur during the recording."

One could say that there is a war going on between alien invaders and natives, involving supreme alien weaponry spewing invisible death rays etc but also strong resistance by huge number of natives. In the end, we know that the natives will prevail.

The above description is absolutely true, depending on the perceived meaning of a few words. Robert Graves, in his novel "Hercules, My Cotraveler" says that this gift of deceiving with words was given by Hermes to his priests. 🙃
