Since it sounds like TWINS is will be keeping close to real-time sampling (twice/second), it would seem possible to run logic that would trigger upon profiles of any dust devil or other significant pressure events passing over the station so that it could automatically record image sequences in hopes of capturing detailed sequences of such events. The same data could keep the IDC aligned with the prevailing wind vectors and be able to catch them soon as they pass over, presuming dust devils tend to travel with the prevailing winds and don't veer too wildly..

What sort of things do you think they might do with the cameras once all the important instruments are deployed and working? Mosaic of the soil near the lander? A nice time lapse showing a complete Martian sol at maybe one frame a minute?


Nothing, the mission is to listen absolutely quietly for quakes.

Any idea what will be done with the arm? Obviously nothing kinetic, but I was wondering if there was some position it could be placed in to assist in reducing noise from the cables or lander.

Maybe not...

"On InSight, guarded move command capability will enable IDA physical properties experiments enumerated in Golombek et al. (2018) such as indentation, collapse of trench walls, and scraped and excavated dump piles."

"The IDA can be used to generate sand/soil piles of different size and aspect ratios next to the lander (Fig. 12). Those piles could be monitored with the cameras for generating time series of the piles and their immediate surroundings. Ideally the evolution of the shape of the piles may be tracked by taking stereo images at regular intervals or after the wind blows. Depending on the wind activity (as measured by APSS), if a sand pile were to migrate away from the lander, a second pile could be created. Wind data can be collected and combined with the camera images for time lapse monitoring of changes...

The IDA has a scoop that can be used to conduct backhoe-style trenching, scraping, and scooping activities at the landing site...

The material scooped up by the arm during trenching or scraping can also be used to create a pile, which can be observed by the cameras. Multiple scoops and dumping procedures could build up larger piles."

Nice (maybe) smile.gif Thanks Phil, I wonder if they considered dumping some scoops of regolith on the SEIS tether to keep it at more even temperature during the day / night cycles to prevent / reduce thermal expansion? (edited)
Meanwhile the Sol 52 images are down (link)
Some movement of the scoop on the slightly above and what appears to be the far side of the tether pinning mass, but I cant see any contact or movement in the tether. Maybe it was just a dry run? Attached is a simple GIF using 2 ICC frames, other frames were taken later in the day with the ICC and IDC, one IDC has data drop out! Maybe that's the one that could have shown any movement in the shunt on the side of the loop? sad.gif

New images are on the InSight mission server, (sol 53) but I'm not sure what they are showing. There are also Some new images from sols 50 and 52
