Some press from JPL about the findings from the RISE instrument:
https://www.jpl.nasa.gov/news/nasa-insight-...spinning-faster Good to hear about quality data from this idea, which was something they wanted to do with MER, had ever one of the two stopped moving while power positive. IIRC. |

Late on Sol 1222 of its total 1440, Insight detected its largest quake during the hours it happened to be listening.
It is now presumed to be tectonic, as no evidence of an impact was detected from orbiters. https://agupubs.onlinelibrary.wiley.com/doi...29/2023GL103619 https://www.ox.ac.uk/news/2023-10-17-new-st...ever-mars-quake QUOTE The S1222a marsquake detected by InSight on 4 May 2022 was the largest of the mission, at M4.7. Given its resemblance to two other large seismic events (S1000a and S1094b), which were associated with the formation of fresh craters, we undertook a search for a fresh crater associated with S1222a.

I'd love to see a final visualization like this one:

And on Planetary Radio it sounded like by 1222 the instrument might have been off during noisy parts of the day, so final sols might cut out midday, when they never heard much. |

Impact rate higher as measured than theorized:

A number of media articles on this paper today:
https://www.pnas.org/doi/10.1073/pnas.2409983121 QUOTE 10 km of crust with porosity of 0.1 to 0.2 translates to 1 to 2 km of water—more than the water volumes proposed to have filled hypothesized ancient Martian oceans (2). Thus, Mars’ crust need not have lost most of its water via atmospheric escape. Liquid water in the pores of the mid-crust also requires high enough permeability and warm enough temperatures in the shallow crust to permit exchange between the surface and greater depths. While available data are best explained by a water-saturated mid-crust, our results highlight the value of geophysical measurements and better constraints on the mineralogy and composition of Mars’ crust. The root of the author quotes in media appears to be this UC Berkeley release: https://news.berkeley.edu/2024/08/12/scient...oo-deep-to-tap/ |
