InSight robot arm to help mole dig


Pioneer cover

From the press release: From the moment he is handed a possibility of making the first alien contact, Saunders Maxwell decides he will do it, even if doing so takes him through hell and back.

 
Unfortunately, that is exactly where that journey takes him.

 
The vision that Zimmerman paints of vibrant human colonies on the Moon, Mars, the asteroids, and beyond, indomitably fighting the harsh lifeless environment of space to build new societies, captures perfectly the emerging space race we see today.


He also captures in Pioneer the heart of the human spirit, willing to push forward no matter the odds, no matter the cost. It is that spirit that will make the exploration of the heavens possible, forever, into the never-ending future.

Mole in hole, with robot arm and scoop above

In their effort to solve the issues that have prevented InSight’s mole from penetrating more than fourteen inches into the ground on Mars, engineers now plan to use the scoop on the robot arm to “pin” the mole up against one wall of the hole so that it will have the friction necessary to drill downward.

The image to the right, cropped and reduced to post here, illustrates what they have been doing and what they will do. Previously the hole was much larger, which prevented the mole from moving downward because it needed the friction from the material around it to hold it in place after each hammer action. (Think of pounding a nail into a wooden board: The nail is gripped tightly by the wood around it as it goes down, so that after each hit it goes further in.)

Since June they have been using the arm and scoop to fill in the hole around the mole. Now I think they intend to bring the scoop around to the mole’s left side, as shown in the image, and pin it upright against the right wall of the hole. When it resumes hammer-drilling they hope both the wall and the scoop will provide enough friction for the mole to drill downward.

Readers!
 

Every July, to celebrate the anniversary of the start of Behind the Black in 2010, I hold a month-long fund-raising campaign to make it possible for me to continue my work here for another year.
 

This year's fund-raising drive however is more significant in that it is also the 10th anniversary of this website's founding. It is hard to believe, but I have been doing this for a full decade, during which I have written more than 22,000 posts, of which more than 1,000 were essays and almost 2,600 were evening pauses.
 

This year's fund drive is also more important because of the growing intolerance of free speech and dissent in American culture. Increasingly people who don't like what they read are blatantly acting to blackball sites like mine. I have tried to insulate myself from this tyrannical effort by not depending on Google advertising or cross-posts Facebook or Twitter. Though this prevents them from having a hold on me, it also acts to limit my exposure.
 

Therefore, I hope you will please consider donating to Behind the Black, by giving either a one-time contribution or a regular subscription, as outlined in the tip jar below. Your support will allow me to continue covering science and culture as I have for the past twenty years, independent and free from any outside influence.

    This really illustrates the value of people over robots. A person would just figure how to get the job done mostly by experience and/or intuition. With a gut feeling on a variety of approaches that are tried over the course of minutes rather than months. Of course, getting a fragile, but versatile, human is needed first.
