Congratulations to the InSight team on a successful landing! We'll discuss the remainder of the mission here.
-------------------- 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.

What about the insulating effect of sand on heat flow? Ideally, wouldn't both the seismometer and the heat probe prefer not to be insulated from the bedrock by something porous and absorbent, like a layer of sand? The instruments may have been designed to see through a certain amount of softer material, but I don't see how it can fail to have some muffling effect.
We may hope that the ease-of-placement benefits of the sandy terrain can outweigh the sensitivity costs. |

wouldn't both the seismometer and the heat probe prefer not to be insulated from the bedrock by something porous and absorbent, like a layer of sand? As I understand it, Seis (seismometer) and Hp3 (heat probe) are optimal in opposite situations, but are both workable in the expected middle ground that insight actually got. The seismometer is designed to be supremely sensitive https://www.seis-insight.eu/en/public-2/sei...trument/summary Seems like that experiment wants no regolith to get best vibration, but they're confident that they can work with regolith. The heat probe is designed to burrow through up to 5 meters of regolith, then (perhaps) hits bedrock. https://www.seis-insight.eu/en/public-2/the...her-instruments That experiment WANTS a deep regolith to get heat flow numbers. |
