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

Curiosity’s new drilling technique declared a success

In order to bypass a failed feed mechanism in the rover’s drill, Curiosity’s engineering team has declared successful the new techniques they have developed for drilling and getting samples.

They had successfully completed a new drill hole two weeks ago, but are only now are satisfied that the new method for depositing samples in the laboratories will work.

This delivery method had already been successfully tested at JPL. But that’s here on Earth; on Mars, the thin, dry atmosphere provides very different conditions for powder falling out of the drill. “On Mars we have to try and estimate visually whether this is working, just by looking at images of how much powder falls out,” said John Michael Moorokian of JPL, the engineer who led development of the new sample delivery method. “We’re talking about as little as half a baby aspirin worth of sample.”

Too little powder, and the laboratories can’t provide accurate analyses. Too much, and it could overfill the instruments, clogging parts or contaminating future measurements. A successful test of the delivery method on May 22 led to even further improvements in the delivery technique.

Part of the challenge is that Curiosity’s drill is now permanently extended. That new configuration no longer gives it access to a special device that sieves and portions drilled samples in precise amounts. That device, called the Collection and Handling for In-Situ Martian Rock Analysis (CHIMRA), played an important role in delivering measured portions of sample to the laboratories inside the rover.

I suspect that they still need to do more tests, and that the new method of shaking off material from the drill itself will not always work. At the same time, it reopens the option of using the drill and getting samples from it, which is a very good thing.

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.
