Nice job pulling out those details, Phil. I think we can even see the shadow of the SEIS shield to its right now!
The illumination on the shield, the fact that the sky appears to be brighter towards the left of the frame, and the putative shadow all point to illumination from the left, ie from the east. |

And the mole is on the move again on Sol 373 Digging deeper into Mars...

Now how will they prevented what happened last time, once it got too low for the arm to keep pinning?

A tweet posted to the Insight Twitter account today states: "The @NASAInSight seismometer has discovered a strange, continuous signal at 2.4 Hz, apparently not related to the lander or weather activity, but excited by a lot of #MarsQuake. This puzzling resonance acts as a natural seismic amplifier!"

Does anyone know if there are any preliminary results from the RISE experiment?

a quick recap of InSight's first scientific results on today's Nature
‘Marsquakes’ reveal red planet’s hidden geology I think I read somewhere that the first papers were going to be published this week in Science (or Nature) but I'm not sure |

“…but that they expected InSight’s landing place to have cohesionless soils because that’s what other Martian landing sites have been like.
InSight seems to have been unlucky enough to land in a place where the soil is compacted into a harder material called a duricrust,…” What would have happened if they had landed at VL or VL2 landing sites, with high soil cohesion ?

Last hammer session of the year on sol 380
Animated IDC GIF: indicates a slowing of progress as the session progressed, then a minuscule bounce? before a little more downward progress? Hopefully a few more images in the pipeline

Almost as if it is running into something hard.

QUOTE (ddeerrff @ Dec 23 2019, 11:37 AM) Almost as if it is running into something hard. The team mentioned a hard duricrust layer, I'm not sure if they know how thick that layer is, but progress of the mole slowed at this depth last time. Fingers crossed it's almost through that harder layer... |
