Thanks, Propguy. smile.gif

Quick question re the WTS: How much is it expected to reduce the amount of temperature variation?

I imagine that the soil covered by the WTS will provide some extra heat capacity that will stabilize the temp variation somewhat more than the air temperature

Right, and the anchors on the seismometer will also stab down into the soil a bit to provide better surface bonding for signal detection, which will also help with temperature stabilization.

I suspect that the W is the primary purpose of WTS, not the T. smile.gif

This pdf -https://ttu-ir.tdl.org/ttu-ir/bitstream/handle/2346/59518/ICES-2014-64.pdf


Charts - especially on pages 14 and 15 - show the WTS, combined with a small heater on SEIS itself - makes quite a dramatic different to the temperature swings experiences by SEIS.

I've done a V2 of my workspace model, complete with WebVR scaling - https://sketchfab.com/models/038d4924308f4c...00fe492b1450997 - I think it's to approx the right scale - I used the width of the blue margin in this image - https://photojournal.jpl.nasa.gov/catalog/PIA22874 - as a guide ( as the blue margin represents the radius of the SEIS WTS I believe )

As a result - take these with a pinch of salt - but an orthoimage and a dem with a 50cm grid overlay, attached.

Thanks for that thermal paper, Doug. Dramatic improvement indeed, and I was unaware of the heater. Count me as a WTS fan, emphasis on the T! smile.gif


Re your DEM: The scale is cm for the elevation contours, right? Regardless, hard to ask for a flatter place than that.

The DEM scale is M, so about 15cm across the entire thing. Incredibly flat.

Here is my take on the sol 14 panorama of the landing site. I prepare a version with a filled sky.

The orbital view shows blast effects out to roughly 20 metres or so from Insight. So Phil's circular post showing us at a "bull's eye" location is probably just due to the engines - there's nothing too unusual about the location.
