SEIS Installation 3, the installation of the Wind and Thermal Shield, is posted here (translated by Google in the first)

the thermal performances are very good, and the impact on the temperature variations of the different components of the seismometer is clearly visible. Finally, the reduction of the noise level is absolutely spectacular


They were briefly worried about the skirt being stuck, but it's good.

"At that moment, nothing that moves on Mars will be able to escape the seismometer of the probe InSight "

That sounds awesome.

Hmm. I suppose that means that it'll be able to pick up those seasonal polar cap landslides in the north, then. Hopefully there will be an effort to correlate seismic signals with those events, presumably via MRO before-and-after imagery.

A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

From a scientific point of view, I have to admit that I may have been a little bit over enthusiastic with the last sentence of the WTS news quoted just above !

Given the sensibility of SEIS's seismic sensors, and the noise level we have under the WTS, we are in a good place to detect very small ground displacements. But, it is only true if the seismic energy is able to reach the seismometer ! If the seismic waves are strongly attenuated by something (such as the regolith ?), if SEIS is in a shadow zone of a given quake, or if the source is very far away (epicenter opposite to the landing site, meaning on the other side of the planet, etc.), we will not be able to detect something. That's the problem with having only one seismometer. Of course, planetary geophysicists wanted a seismic/atm networks from the very beginning (see for example the incredible scope of the MESUR project in 1990's), but having InSight with its single seismometer at the surface of Mars was already excruciatingly difficult.

HP3 is on the ground!





I wonder what happened with the positioning of the arm though. The grapple is hanging at an odd angle now.

DLR is happy:

It's a lot closer to SEIS than I was expecting.

Heck yes. Looks scary close to a super sensitive seismometer. But in hindsight, it could never be very far away and I'm sure the dynamics are well understood.

There's a new article on the Insight page though doesn't say much new other than it being deployed ~1 meter from SEIS
