Readers!
 

My annual February birthday month fund-raising campaign for Behind the Black is now over. It was the best February campaign ever, and the second best of all of my month-long fund-raising campaigns.

 

There were too many people who contributed to thank you all personally. If I did so I would not have time for the next day or so to actually do any further posts, and I suspect my supporters would prefer me posting on space and culture over getting individual thank you notes.

 

Let this public thank suffice. I say this often, but I must tell you all that you cannot imagine how much your support means to me. I’ve spent my life fighting a culture hostile to my perspective, a hostility that has often served to squelch my success. Your donations have now allowed me to bypass that hostility to reach a large audience.

 

Even though the February campaign is over, if you still wish to donate or subscribe you still can do so. Regular readers can support Behind The Black with a contribution via paypal:

If Paypal doesn't work for you, you can support Behind The Black directly by sending your donation by check, payable to Robert Zimmerman, to

Engineers develop new technique to resume drill use on Curiosity

Engineers have successfully tested a new drill procedure on a duplicate rover on Earth that bypasses the problem in Curiosity’s drill.

The problem with the drill has been its feed mechanism, which pushes the drill bit downward as it drills its hole. The tests with the duplicate rover on Earth have instead had the drill bit fully extended and used the robot arm itself to push downward. It worked, but the problem on Mars is holding the drill bit perfectly straight and not slipping sideways. They are now doing a test with Curiosity to address this.

Curiosity touched its drill to the ground Oct. 17 for the first time in 10 months. It pressed the drill bit downward, and then applied smaller sideways forces while taking measurements with a force sensor. “This is the first time we’ve ever placed the drill bit directly on a Martian rock without stabilizers,” said JPL’s Douglas Klein, chief engineer for the mission’s return-to-drilling development. “The test is to gain better understanding of how the force/torque sensor on the arm provides information about side forces.”

This sensor gives the arm a sense of touch about how hard it is pressing down or sideways. Avoiding too much side force in drilling into a rock and extracting the bit from the rock is crucial to avoid having the bit get stuck in the rock.

Stay tuned for a Mars rover update, coming shortly!

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.
