    InSight has successfully placed its seismometer on Mars, and the lander has also placed a dust cover on it. It has also placed a sort of hammer drill on it, a "mole". This is to burrow down underneath the soil, to get an idea of the heat flow from Mars's interior. But...

    InSight Lander's Drill Got Stuck on a Rock During Its First Dig Into Mars
    NASA InSight on Twitter: "Giving my robotic mole a rest for a bit, as it seems to have come up against one or more rocks. While my team works on how best to overcome this obstacle, I’ve got some eclipse science ahead as Mars’ moon Phobos passes in front of the Sun this week: https://t.co/weuioEkrpG"

    NASA hatches plan to solve Mars InSight mole mystery - CNET noting DLR - Blogs - All blog posts - The InSight mission logbook:
    Logbook entry: 22 March 2019

    The Anomaly Response Team today has approved of our way forward. Accordingly, the next steps for HP3 will be:

    Command a TEM-A thermal conductivity measurement today to be executed over the weekend. The measurement takes 24 hours. On Monday, command the diagnostic hammering and image taking I was describing in my previous post to be executed in the afternoon of the next sol on Mars with data being downlinked coming Wednesday. We may then have to take some time to evaluate the data.

    Stay tuned and keep your fingers crossed!

    A lot of stuff on trying to get the "mole" back into action, starting by removing its cover. The mole made a hole about twice its diameter, something surprising to the lander's operators. They are thinking of getting the lander to shovel dirt into that hole, to give the mole's sides more friction.

    Here's an article on Mars Methane that may be of interest;


    ''On Mars, methane production appears to be seasonal in nature, fluctuating from about 0.24 parts per billion (ppb) in the northern hemisphere during winter to about 0.65 ppb during the summer.

    At the same time, extended plumes have been detected which shows that it is also periodically released from discrete regions. On two occasions, the Curiosity rover happened to be in the vicinity of plumes; in December of 2014 and again back in June.''
