Future of InSight’s heat probe dim


Week Four: Ninth Anniversary Fund-Raising Drive for Behind the Black
 

The fourth week of my annual anniversary fund-raising campaign for Behind the Black has begun.


I once again must thank the many readers and listeners who have generously donated this month. Right now there is a chance this will be the best fund-raiser ever, though only if a lot of people donate during the month's last ten days. If you want to help me continue my reporting, you can give a one-time contribution, from $5 to $100, or a regular subscription for as little as $2 per month.


For one time donations via Paypal, click here:

Blocked after drilling down only one foot instead of fifteen, engineers are increasingly worried that they will not be able to get InSight’s heat probe past whatever is blocking to so it can begin getting data of Mars’s inner thermal environment.

They are considering a bunch of options, including using InSight’s robot arm to either give the probe a nudge to help it get past the obstruction, or even use the arm to push the probe.

None of the options are encouraging it seems.

    The Apollo missions showed how difficult drilling in situ can be. I thought from the first I read of this mission, with no roving capabilities, blind drilling is going to need some pure luck. Nasa/JPL really seemed to pitch this part of the mission as a piece of cake…

    Agree. Chances of success must have been 50/50 at best. The amount of rock under the surface must be all encompassing

    So…they seriously thought they could go down 15 feet, without encountering a single glitch? I’d like to see the statistical analysis that was made (or not) of this eventuality. Somebody thought it was a great idea and signed off on it, time for them to become famous.
    What is Plan “B” and Plan “C”?

    How do we know that there isn’t just a solid layer of bedrock under a thin layer of soil?

    To bad they can’t just pull it back up and move it over a foot.

    I agree with all of the above…. The most we have checked out Martian soil is a few centimetres… And there is bedrock poking out everywhere…. I presumed this little mole probe would have rock breaking capabilities….
    Has the probe hit bedrock?
    If a pebble can wreck the mission, someone should be held accountable for such a stupid oversight…

    Mars2020 will have a Ground Penetrating Radar. Perhaps useful before digging around I guess.

    Wayne, that Armageddon link you sent should be daily required viewing for anyone in the USG space biz, Tx!
