Olympus Mons and Valles Marineris, and North-South dichotomy boundary are seismically active regions on Mars
New analysis of Mars Insights data found apart from Cerberus fossae, seismicity on Mars occurs mostly along or north of the boundary between the southern highlands and northern lowlands. Valles Marineris is seismically more active than previous catalogs of located events imply. Further, there is evidence that two events likely originate from the Olympus Mons region. Tharsis region is found to be more active than initially perceived on the basis of five newly located seismic events near Valles Marineris and Olympus Mons.

Mars has a smaller and denser core, surrounded by a molten silicate mantle
Analysis of Mars Insights data shows Mars has a smaller and denser core, surrounded by a molten silicate mantle.
Sandwiched between Mars's liquid iron alloy core and its solid silicate mantle lies a layer of liquid silicate (magma) about 150 kilometres thick. "Earth doesn't have a completely molten silicate layer like that".
The new observations show that the radius of the Martian core has decreased from the initially determined range of 1,800-1,850 kilometres to somewhere in the range of 1,650- 1,700 kilometres, which is about 50 percent of the radius of Mars. If the Martian core is smaller than previously thought but has the same mass, it follows that its density is greater and that it, therefore, contains fewer light elements. The fact that the Martian core still contains a significant amount of light elements indicates that it must have formed very early, possibly when the Sun was still surrounded by the nebula gas from which light elements could have accumulated in the Martian core.

The largest quake on Mars (4.7 magnitude) has an internal origin and is not the result of an asteroid impact.
During its time on Mars, NASA's InSight (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) mission recorded over 1,300 seismic events, known as “marsquakes.” Of these, a number were identified as coming from meteoroid impact cratering events on the surface.
The largest event identified by InSight, labeled S1222a, bore some similarities to two large impact events recorded earlier in the mission. In order to investigate whether the S1222a event might also have been caused by an impact event, scientists internationally collaborated and undertook a comprehensive search of the region in which the marsquake occurred. They did not identify any fresh craters in the area, implying that the marsquake was likely caused by geological processes.

The end is nigh my friends.
Noticed the team on Twitter just announced that the raw images from today could very well be the last ones we get from the lander. Sad times for sure

I’m getting close to the end here, due to dust gathering on my solar panels, making it hard to generate power. People often ask: don’t I have a way to dust myself off (wiper, blower, etc.)? It’s a fair question, and the short answer is this:

The day is coming when fall silent, ending my nearly four Earth years (over two Mars years) of studying the Red Planet.

I just grabbed the last 3 images, Sols 1219, 1221 & 1223. These cross the boundary of Sol 1222 Mars quake, Sol 1221 was on May 4th. note grapple AND ribbon moving.

I’ve been looking at recent photos and something seems strange. On sol 1211 they seem to have sat the scoop on the deck and bumped a support arm with the grapple! Image credit: NASA/JPL-Caltech

Would the mars helicopter be able to dust off insight's solar panels?
Would the mars helicopter be able to dust off insight's solar panels any more than the winds could? I read about it being pretty dusty and might not be able to power itself through the summer.

Question. When will measurements continue and uploaded to the API
In my previous post, I asked why the Insight Weather API was not updating the weather information, this was because of the winter. The following link was posted in the comments.
https://mars.nasa.gov/news/8858/insight-is-meeting-the-challenge-of-winter-on-dusty-mars
This article states that the measurements will continue when the winter is over.
" Mars will start approaching the Sun again in July 2021, after which the team will begin to resume full science operations."
Does this mean the heaters still require more power they hoped for? Or maybe I missed something in the article.
Thanks in advance for answering my question.
