I saw only one scoop a few hours ago .Hot off the press Someone shared this with me after I posted here: from Twitter after the 1st scoop (roughly translated from French) QUOTE First step of scraping the regolith! Several methods will be tested to form the piles in which the scoop will collect the material that will be deposited on the cable (tether), at specific locations.... Tweet |

The second trench, on sol 803, was made with three passes of the scoop. The first trench used only one.

Hello,
The first dump will be on the thermal shield, the regolithe will slide on the cable. This avoids touching the shield with the shovel, while ensuring it is close enough to the junction with the shield base. we repeated this on Earth, to better visualize the operation https://twitter.com/i/status/1370408682752770052 https://mars.nasa.gov/insight/multimedia/ra...mission=insight The result of this first emptying of the bucket is not perfect but the continuation is expected

Nice! Did the soil dump actually leave a clean mark on the thermal shield?

A pity the same trick won't work on the solar panels...

That's cool to have the interior of Mars constrained, and at almost the same time that the same could be said of Jupiter and Saturn. This decade has been a Golden Age of interior planetary science!
It's interesting that there are two kinds of noise that have become prominent: Wind and severe day-night temperature changes. I'd say that it's a matter of perspective how much those factors are interfering with our study of martian seismology vs. how much those factors are part of martian seismology. We come in with terrestrial bias presuming that certain kinds of systems are largely independent from one another and those systems might be more interrelated somewhere else. I suppose by analogy, when you make a map of Antarctica, you have a decision of whether you want to map the land and ignore the ice or if you want to map the ice because that's "land" there. On Mars, wind and weather get involved in the seismology. I don't think it's too presumptuous to suppose that at the right time and place, a tremble begun with those factors might cause some downslope mass movement that counts as a real mars-quake. |

Nice to see a mission objective completed.

QUOTE (moustifouette @ Mar 18 2021, 12:03 PM) There's something perverse about this remark "Stähler declined an interview request from Nature, saying the team intends to submit the work for publication in a peer-reviewed journal." This is basically reflecting that Science and Nature have an editorial policy that they will not publish (peer-reviewed) papers if the authors have engaged with the media about the results. Presenting at a conference is ok, but not talking to reporters afterwards. Even if the reporters are writing for the news pages of Science/Nature..... Seems like Science/Nature want to have it both ways, get the clicks/ad revenue for news stories, and get the traffic for the papers themselves (and, depending on journal setting, get open access fees for publishing the paper...) |
