    "A Year of Surprising Science From NASA's InSight Mars Mission"

    https://www.jpl.nasa.gov/news/news.php?feature=7605

    A new understanding of Mars is beginning to emerge, thanks to the first year of NASA's InSight lander mission. Findings described in a set of six papers published today reveal a planet alive with quakes, dust devils and strange magnetic pulses.

    Five of the papers were published in Nature. An additional paper in Nature Geoscience details the InSight spacecraft's landing site, a shallow crater nicknamed "Homestead hollow" in a region called Elysium Planitia.

    InSight is the first mission dedicated to looking deep beneath the Martian surface. Among its science tools are a seismometer for detecting quakes, sensors for gauging wind and air pressure, a magnetometer, and a heat flow probe designed to take the planet's temperature.

    Second, just so you know, it is considered good form around here to include a little more info about a link that just the post/thread title. In this particular example, it might have been better just to link the original Business Insider article and quote some small section from it.

    There's a BBC Science article addressing it. There seems to be a higher incidence of "marsquakes" than anticipated, as detected by InSight's seismometer.

    https://www.bbc.com/news/science-environment-51616830

    Also, the magnetic field at InSight's location is up to 10x stronger than expected from models generated from orbital data:

    Perhaps merge this into the existing InSight thread?

    "NASA's Mole Finally Burrows Its Way Into Mars"

    https://www.popularmechanics.com/spa...le-probe-mars/

    One instrument, though, has had a difficult time breaking through the surface. The lander's temperature-sensing "mole," as it's known, was designed to take thermal readings just below Mars's surface, but it has struggled to stay inserted in the ground. It keeps pushing out.

    The German Aerospace Center (DLR), which is in charge of operating the instrument, has been toiling away at a solution. For months, the DLR team has been pushing down on the thin probe with the back of the lander's scoop. Finally, after spending more than a year of tinkering with the troublesome instrument, DLR has inserted the mole.

    It took 6.02x10^23 attempts.

    Hopefully, it can continue on its own accord. Otherwise, this may be as deep as it gets.

    Mars Insight Lander

    If the mole is committed to that angle then I don’t see how it will reach the planned depth, although it can likely still take readings. Just not as deep.

    Truly, an exercise in patience.

    "'Marsquakes' measured by InSight show effects of sun and wind"

    https://www.marsdaily.com/reports/Mi..._wind_999.html

    Compared with our own planet Earth, Mars might seem like a "dead" planet, but even there, the wind blows and the ground moves. On Earth, we study the ambient seismic noise rippling mainly due to ocean activity to peek underground at the structure of the Earth's interior. Can we do the same on Mars without ocean?

    According to a new study by researchers at Kyushu University's International Institute for Carbon-Neutral Energy Research, we're closer than ever to achieving this goal.

    "NASA engineers checking InSight's weather sensors"

    https://www.spacedaily.com/reports/N...nsors_999.html

    Weather sensors aboard NASA's InSight Mars lander stopped providing data on Sunday, Aug. 16, 2020, a result of an issue affecting the sensor suite's electronics. Engineers at NASA's Jet Propulsion Laboratory in Southern California are working to understand the cause of the issue.

    "Mars lander InSight picks up tiny ground tilt caused by Phobos moon transit"

    https://www.space.com/mars-lander-in...-eclipses.html

    NASA's InSight Mars lander can detect a nearly imperceptible tilt caused by the planet's moon Phobos passing in front of the sun, scientists have realized.

    And the measurements may help scientists pin down a number of eclectic facts about Mars and Phobos, particularly if InSight remains at work beyond its two-year primary mission, which runs out this fall. The new research is just the sort of science that wasn't on InSight's agenda but is an unexpected bonus discovered in the data.

    "It's a completely lucky observation," Simon Stähler, lead author on the new research and a seismologist at ETH Zürich in Switzerland, told Space.com. "It could have been planned before, but we never did. But now we found it."

    I was unclear why it had to be passing in front of the sun to have an effect - surely the imperceptible tilt is there whenever Phobos passes near enough overhead? But they are actually talking about a "tilt"
    imparted by a change in the light - the number of photons hitting the spacecraft (and surface of Mars)! Very interesting article, selvaarchi!

    I'm seeing reports that the lander's weather station isn't working, but I'm not sure about the sources. Anyone got something authoritative?

    "NASA’s Insight Mars lander rescue operation makes progress saving ‘stuck’ probe"

    https://www.teslarati.com/nasa-insig...ission-update/

    The scientists running NASA’s Insight Mars lander found themselves attempting a rescue operation for the mission when one of its instruments became stuck in the red planet’s regolith early last year. After a few assistance maneuvers using a robotic shovel-clad arm in the months since, it appears the team has finally reached a point where there’s light at the end of the dusty tunnel.

    “Another short test has my self-hammering mole making gradual progress. Pressing down on the soil above has helped it dig a little further. We’ll do another of these moves soon,” the lander’s official Twitter page announced recently.

    "NASA InSight's 'Mole' is out of sight"

    https://www.marsdaily.com/reports/NA...sight_999.html

    NASA's InSight lander continues working to get its "mole" - a 16-inch-long (40-centimeter-long) pile driver and heat probe - deep below the surface of Mars. A camera on InSight's arm recently took images of the now partially filled-in "mole hole," showing only the device's science tether protruding from the ground.
